The BoilerMate 2000 shown schemat ically ab ove is designed to provide improved space

heat ing and m ains pressure hot w ater when coupled to any remotely sited condensingor non condensing boiler - as long as they comply with the recommendations

contained in the rest of t his manual.

A report b y the Cranfi eld Institute o f Techno logy found tha t this system g ives a

potential for energy sa vings of up to 15%.

Because of the efficiency of the appliance improved SAP ratings can be achieved.

Further deta ils a re ava ilab le from t he Gledhill Technical Depa rtment .

The principle of a BoilerMate 2000 is to separat e th e hea t g enerator e.g. a bo ilerfrom heat emitters (radiators) by a thermal store, which evens out the fluctuating

dema nds for heating a nd hot wa ter. Thus, by storing energy produced when t hedema nd is low a nd d ischarging it whe n the demand is high (i.e. during property

wa rm up or wh en hot w ater is drawn o ff), a sma ller boiler can poten tially be used.

An important fea ture of this concept is that hot w ater can be supplied d irectly from

the ma ins at conventional flow rates without t he need for temperature and pressure

relief safet y valves or expansion vessels. This is achieved by pa ssing the ma inswa ter through a plate hea t exchanger. The outlet temperature of the domestic

hot water is maintained by a printed circuit board, which controls the speed of

the pump circulating the primary w ater from the store through t he plate hea t

exchanger.

To co mply w ith th e Benchma rk Guidance Note for Water Treatmen t in hea ting andhot w ater systems th e installer should check the ha rdness levels of the wa ter supply

and if necessary fit an in-line scale inhibitor/reducer to provide protect ion to t he

who le of the domestic wa ter system.

Description

1.1 INTRODUCTION

If scale should ever become a problem the plateheat exchanger is easily isolated and quickly

replaced with a service exchange unit which

can be ob ta ined at a nominal cost from Gledhill.

For further deta ils see Section 1 Hot and Cold

Wat er System page 10.

The pcb also incorporates the facility to operate

the heat ing pump for a few seconds every few

days when the heating is not being used, to

reduce the likelihood of the pumps sticking

as well as providing a boiler pump overrun

facility.

Any automa tic boiler designed to operate on an

820C flow and a 710C return up to a maximum

of 35kWcan be linked to a ny suitable mod el of

BoilerMate 2000 and the d eciding factor is the

space heating and the hot w ater requirementsof a dw elling . See Section 1.2 Technica l Data for

further det ails.

The BoilerMat e 2000 is availab le w ith t he

option of ‘Switch’ which will provide a 9kWelectrical emergency b ackup in case of fa ilure

of the m ain heat source. See section 1.3 System

1.3 SYSTEM DETAILS

Hot and Cold Water System

General

A schematic layout of the hot and cold water services in a typical small dwelling is

show n below . BoilerMate 2000 will operate at mains pressures as low a s 1 bar and a s

high as 5 ba r although th e recommended rang e is 2-3 ba r. If the manifolds (availab le as

an optional extra) are being used the inlet pressure to the ma nifold must be a minimum

of 2 ba r. It is also importa nt to check tha t all othe r eq uipment and comp onent s in

the hot and cold wa ter system a re capable of accepting t he mains pressure availab leto the property. If the mains pressure can rise ab ove 5 bar or the ma ximum wo rking

pressure of a ny item of eq uipment or component to be fi tted in the system a pressure

limiting (reducing) valve set to 3 ba r will be required.

If you encounter a situation where the w ater pressure is adeq uate b ut flow rates are

poor please co nta ct our technical helpline for det ails of an e ffective solution.

Note: Each BoilerMate 2000 is fitt ed w ith a strainer and fl ow regulato r on the cold

mains supply connection. If the supply pressure is less than 2 bar or if the ma nifolds

(available as an optional extra) are being used or if all taps are provided with flow

regulators the fl ow regulator on the cold inlet should be removed.

No check valve or similar device should be fitted on the cold water supply branch

to the BoilerMate 2000.

To com ply with the Benchmark Guidance Note for Water Treat ment in Heating an d

Hot Water Systems t he insta ller should check the ha rdness level of the w ater supply

and if necessary fit an in-line scale inhibitor/reducer to provide protect ion to t hewh ole of the do mestic wa ter system. See Append ix C for a copy of the relevant pa rt

of the Benchm ark Guidance Note.

1.0 DESIGN

When specifying th is app lian ce we w ould

recommend that for hardness levels above

200ppm (mg/l) a hard w at er appliance is used.

For ha rdness levels above 250ppm (mg/l) we

would recommend that some form of in-line

scale inhibitor/reducer is recommended by oneof t he Water Treatmen t compa nies listed in the

Benchmark Guidan ce Note (see Appen dix C).”

The hot wa ter flow rate from the BoilerMate

2000 is directly related to the adequacy of the

cold water supply to the dw elling. This must

be capa ble of providing for those services,which could be required to be supplied

simultaneously, and this maximum demand

should be calculated using procedures defin ed

in BS 6700.

If a wat er meter is fi tt ed in the service pipe,

it should ha ve a nominal rating t o mat ch the

maximum hot and cold water peak demands

calculat ed in acco rdance with BS 6700. This

could b e up to 80ltr/min in some p ropert ies.

1.3 SYSTEM DETAILS

Hot and Cold Water System

Pipe Sizing / Materials

To a chieve even distribut ion of t he a vailab le supply of hot and cold w at er, it is

important in any mains pressure system, that the piping in a dwelling should be

sized in accordance with BS 6700. This is part icularly importa nt in a large property

with more than one ba throom.

However, the following rule of thumb guide lines should be adequate for most

smaller property types a s long as w ater pressures are within the recommended

range of 2-3 bar.

1. A 15mm copp er or equivalent exte rnal service may b e sufficient for a

small 1bathroom dwelling (depending upon the flow rate available), butthe minimum recommended size for new dwellings is 22mm (25mm MDPE).

2. The internal cold feed from the main incoming stop ta p to the BoilerMat eshould be run in 22mm pipe. The cold ma in and h ot d raw-off should also

be run in 22mm as far as the branch to t he ba th ta p.

3. The fi nal branches to t he hand ba sins and sinks should be in 10mm and t o

the ba ths an d show ers in 15mm. (1 metre minimum)4. We would recommend that best results for a balanced system are achieved

by fitting appropriate flow regulators to each hot and cold outlet. This isparticularly relevant where the water pressures are above the recommendedwater pressure range of 2-3 bar. Details of suitable flow regulators areprovided in Appendix A.

Note: If manifolds (available as an optional extra) are being used suitable flowregulators are automatically provided in the manifold and do not need to beprovided at each outlet - See Appendix B for further details.

All the recommendations with regard to pipework systems in this manual are

generally ba sed on t he use of BS/EN Stand ard copp er pipew ork and fit tings.

However, we a re happy tha t plastic pipework systems can b e used in place of copper

internally as long as the chosen system is recommended for use on domestic hot

and cold water systems by the manufacturer and is installed fully in accordance

with their recommendations.

This is particularly important in relat ion to use of push fi t con nections w hen using

the opt ional flexible ho se kits - see 2.2 Insta llat ion, Pipework connections.

It is also essential tha t if a n a lternat ive pipew ork material/system is chosen the

manufacturer confirms tha t the design criteria of the new system is at least eq uivalentto t he use of BS/EN Stand ard cop per pipework and fi tt ings.

Taps/Shower Fittings

Aerated taps are recommended to prevent splashing.

Any type of shower mixing valve can be used as long as both the hot and coldsupplies are mains fed. However, all mains pressure systems are subject todynamic changes particularly when other hot and cold taps/showers are openedand closed, which will cause changes in the water temperature at mixed wateroutlets such as showers. For this reason and because these are now no moreexpensive than a manual shower we strongly recommend the use of thermostaticshowers with this appliance.The shower head provided must also be suitable for mains pressure supplies.

However, if it is proposed to use a ‘whole b ody’ or similar show er with a numbe r ofhigh fl ow /pressure out lets please discuss with the Gledhill technical dep artment.

1.0 DESIGN

The ho t w ater supply to a show er-mixing va lve

should be fed w herever pract ical directly from

the BoilerMate 2000 or be the fi rst draw-off

point o n the h ot circuit. The cold supp ly

to a showe r-mixing valve should w herever

practical be fed d irectly from the rising ma insvia an independ ent branch. The show er must

incorporate or be fitted with the necessary

check valves to provide back-syphonage

protect ion in acco rdance w ith the Wat er

Regulations.

The supply of ho t a nd cold ma ins wa ter directly

to a bidet is permitted provided tha t it is of theover-rim flush ing t ype a nd tha t a type ‘A’ air

gap is incorporated.

Hot and Cold Water System.

If the leng th of the hot wa ter draw off pipework

is excessive an d t he d elivery time w ill be mo re

than 60 seconds b efore hot wa ter is available

at t he tap, you may w ish to consider using t race

heating to the hot wa ter pipework such as theRaychem HWATsystem. Plea se consult Gledhill

Technical Depa rtment for further d eta ils.

It is important that the cold water pipework

is ad eq uate ly separated /protected from a ny

heating/hot wa ter pipework to ensure th atthe wa ter remains cold and of drinking wa ter

quality.

Heating System

General

A schematic layout of the heating system in a

typical small dw elling is shown opposite.

The flow an d return from t he b oiler must

always run directly to the BoilerMate 2000

and the flow should rise continuously to

facilitat e venting . The hea ting circuit is ta ken

from the BoilerMate 2000 and is piped in theconventional manner.

The BoilerMat e 2000 is on ly suitable for an

open vented system.

The F &E cistern can b e fi tted remotely up t o

10m above the base of the BoilerMate 2000

i.e. the maximum static pressure in the store

must no t exceed 1 bar.

If any rad iators are located ab ove the levelof the BoilerMate 2000 the system should

be designed so that gravity circulation does

not occur when the hea ting pump is not

running. To be certa in of preventing t his it is

recommended tha t a check valve, or valves, are

fitt ed on t he vertical flow pipes.

The water level in the F & E cistern should beat least 250mm above the highest point onthe system including the radiators and mustbe high enough to provide the minimumhead required by the boiler being used.

1.3 SYSTEM DETAILS

The bo iler ma nufact urer’s instructions with

regard to minimum head must always be

follow ed . This is pa rticularly impo rta nt insituations where the headroom is restricted

(e.g. in a fla t).

Range rated boilers can be used but should

always be set at the highest ou tp ut . The

Pipe Sizing/Materials

The primary pipew ork connect ing the bo iler and t he thermal store should be sizedto achieve a maximum of 8°C rise across the boiler or the maximum temperature

rise specified by t he b oiler man ufacturer, wh ichever is smaller, but in any instance it

should not be less than 22mm copper tube.

Note: There should b e no va lves in the pipework connect ing the b oiler to the

BoilerMate 2000.

The h eat ing circuit o perates on the normal primary boiler temp eratures i.e. 82°C

flow and 71°C return. Therefore any traditional hot w ater rad iators or convecto rs

can be used with this system and no special over-sizing of the heat emitters isnecessary.

All the recommendations with regard to pipework systems in this manual are

generally ba sed o n the use of BS/EN Stand ard cop per pipework and fi tting s.

However, we are happy that plastic pipework systems can be used in place ofcopper internally as long a s the chosen system is recommended for use on domestic

heat ing syste ms b y t he ma nufacturer and is installed fully in accordance with

their recommendations. We a lways recommend the use of barrier pipe for these

systems.

Heating System

Method of connecting two BoilerMates to one heat source.

If the primary flow and return pipework continuously rises from the boiler to the

BoilerMate the recommended method for connecting two BoilerMates to one hea t

source is to fi t th e BoilerMates as normal but to provide a single check valve on the

branch immediately afte r each primary pump.

The hea ting and hot wa ter from each appliance must serve separate zones/bathroomswithin the property.

The electrical supplies from ea ch app liance to t he boiler will need tw inning so th at

the bo iler will operat e on a ca ll from either/bo th a ppliances.

Both primary pumps and the primary pipework sizes should be checked to e nsurethat t hey are adeq uate for the system that ha s been installed.

If the primary pipework dips or the boiler is located above the BoilerMatea single F & E cistern with a cold feed and open vent piped to the cisternshould be used.

This arrangement is not suitable for BoilerMate appliances fitted with Switch.

If it is proposed to use t his arrang ement please a dvise Gledhill at the time of o rder,

Gledhill will then supply a suitable vent a ssembly for fitting on th e safet y/open vent

connection and a blank for the cold feed connection of each BoilerMate 2000, in

lieu of the F &E cistern no rmally provided .

If the boiler is a long way from the BoilerMate the resistance should be checked

to ensure the pumps cannot produce a negative pressure in the BoilerMateappliance.

The sing le F &E cistern w ill need to b e provided, (by t he installer) an d b e suitablefor the size of the t ota l system insta lled.

‘Switch’

The BoilerMat e 2000 ca n be o rdered w iththe option of ‘Switch’ which provides a 9kW

electrical emergency back up in the case of

failure of the main hea t source i.e. ga s bo iler.

This must NOT be used to provide hotwater only in summer if the main system isworking correctly.

If Switch is ordered the electrical supply willneed to take account of the increased load.

Full details of the requirements are provided

in Section 2.1 Site Requirements and 2.2

Installation.

Otherwise the design requirements are thesame as the sta ndard a ppliance.

Switch can operate on ‘hot w ater’ or ‘hot w ater

and heat ing’ mode s. In the former only hot

wa ter pump and electric heating element are

energized. In the latter the heating systempump is also energ ized. This mea ns tha t

the heating will be on permanently unless

manually switched b ack to t he ‘hot wa ter’ only

position.

I t a l so means that wherever Swi tch i sbeing used the normal domestic hot water

tem perature controls are over-ridden. Initially

depend ent on the flow rate/store temperature

hot water can be delivered at the tap at

temp eratures as hig h as 75°C. A wa rning

notice to this effect is provided in the frontof the appliance.

However, once the initial store t emperature ha s

been reduced the Switch element thermostat

will reduce the temperature at the tap to no

more than 65°C. Full det ails of how to operatethe system are provided on a label fixed to the

front of th e appliance.

Primary Water System Treatment

Althoug h the BoilerMate 2000 has no special

wa ter treatment requirements, the radiators

and other parts of the circuit will benefit

from the application of a scale and corrosion

inhibitor such as Sentinel X100 or a Protectorsuch as Fernox MB1.

When de termining t he q uant ity of inhibitor

required, be sure to allow for the increased

volume of wa ter in the primary circuit due to

the the rmal sto re - see section 1.2 Techn icalDat a for volumes.

In most ca ses the q uantities shown o pposite

will be suitab le for a t ypical 3/4 bed property.

POWERFLUSHING/CLEANING OF THE HEATINGSYSTEM

If it is proposed to ‘powerflush’ the heat ingsystem we would recommend that the

BoilerMate appliance is isolated from the

hea ting system being cleaned. Failure to dothis could seriously damage the appliance.

When carrying o ut the wo rk alwa ys comply

fully with the manufacturers instructions for

the pow erflushing equipment being used.

If in a ny d oubt p lease consult our Technical

Helpline.

Open the incoming stop valve and fi ll the d omestic mains cold a nd ho t w ater

systems.

Fill the w hole of the primary heat ing system with po tab le wat er through the

feed and expansion cistern.

Check the water level in the feed and expansion cistern and adjust the ballvalve

if necessary.

Check the whole of t he primary heating and domestic hot a nd cold d istribution

systems for leaks.

It is essential that all systems function properly for optimum performance.

To a chieve this, the primary system should b e comm issioned in a ccordance with

good practice and generally in accordance with the requirements of BS 6798,

BS 5449 and BS 7593.

Full details of the requirements are given in PAS 33:1999 under Section 10

Commissioning.

When using e ither cleansing or corrosion

inhibi tor chemical , the manufac turers

instructions must be followed .

Cleansing the Primary System

When determining the quantity of cleanserrequired, be sure to allow for the increasedvolume of water in the primary circuit dueto the thermal store.

In most ca ses the q uantities shown o pposite

• If the boiler is range rated, then ad just it to the maximumheat input.

• Check the boiler thermostat is set to maximum.

• Set t he b oiler pump speed so t hat the temperature difference across the

boiler is about 8°C - when the space heating is off. NOTE: For op timum

performance when using a condensing boiler such as the Keston C25 set

the boiler pump in the BoilerMate to give about 15ºC temperature rise across

the bo iler.

• Set the heating system pump speed so tha t the temperat ure difference across

the flow and return is not greater than 11°C.• Check the DHWplate heat exchang er pump is set to maximum.

• Check tha t there is no overflow w hen the who le of the system is fully up

to temperature.

• Check tha t the Y type strainer on the incoming mains cold water inlet to the

app liance is clean.

Note: If the appliance is operating a t mains cold w ater pressures below 1½ bar the

flow regulato r fitted on the outlet to t he Y type strainer can b e removed if required

to improve performance.

Because the A.C.B is able to adjust to suit thewa ter temperatures delivered by the bo iler the

thermostat should always be set a t maximumduring comm issioning.

However, the boiler thermostat setting can be

reduced in summer, in the normal way, if theappliance is being used for hot w ater only.

The temp erature sett ings esta blished during

commissioning can be checked using push

button switches sw1 and sw2 on the PCB as

described in section 3.3 Fault Finding.

The cloc k/prog ramm er provide d o n th e

appliance controls the heating system only

and should be set to suit the householdersrequirements using the instructions show n

on the separate leaflet and the label on thefront of the appliance. If the appliance is fitted

with Switch (see figure on pa ge 25) the b oiler

should be switched off and Switch operated

to ensure it is working co rrectly.

• When the selector knob is not in normal

position, the PCB, room thermostat and

the time clock are electrically isolated .

• When th e select or knob is in HW on ly

position the plate heat exchanger pump

will run cont inuously a t full speed.

• When the selecto r knob is in the HWand

HTG position, the p late h ea t excha ng er

pump and the heating pump will run

continuously.

This product is covered by the ‘Benchmark’scheme and a separate commissioning/service log book is included with thisproduct. This must be completed duringcommissioning and left with the productto meet the Warranty conditions offeredby Gledhill.

On completion:-

1. Do ensure that the electrical connection(e.g. mains supply, room thermostat) to

the uni t i s correct and t ight before

2. Do ensure that the funct ioning and

control of the system is explained to theoccupant.

These Instructions should b e placed along with

the component manufacturers instructions in thepocket provided on t he rear of t he front p ane l.

The front pa nel should then be refitt ed.

2.3 COMMISSIONING

2.0 INSTALLATION

Note: The con trols within the A.C.B will not allow t he hea ting system to funct ion

until the sto re temperature has reach ed 60°C. Therefore althoug h the LED bar 1

‘HT’ will light when hea ting is switched on, the heat ing pump (Green LED -3) will notswitch on if the store tempe rature is less tha n 60°C. Time will need to be allowed for

this to ha ppen d uring initial commissioning. This will vary depend ing on the bo iler

size and the model of the BoilerMate 2000 being used.

2. Once a temperature of 60°C has been reached on th e thermal store, switch on

space hea ting clock/programm er and room thermosta t.

3.4 FAULT FINDING

Despite everyones best efforts some problems could occur and lead to complaints

from the househ older.

Complaints can b e g rouped into the following three main cat ego ries:-

1. The syste m is noisy

2. Hot w ater service is unsatisfacto ry

3. Space heat ing is unsat isfactory

The fo llowing che cks should b e ca rried out by the installer before calling themanufacturer.

1. Causes of a ‘Noisy’ System

Noisy pump op eration

Check the level of w at er in the F &E cistern - ad just a nd ven t t he pump /system

if necessary.Check the pump speed set ting o f the b oiler pump - reduce if necessary but ensure

tha t the t emperature rise across the boiler does not exceed 8°C.

Check the pump speed sett ing of the hea ting pump - reduce if necessary but ensure

a temperature d ifference across the fl ow and return d oes not exceed 11°C.

Check a nd a djust if necessary the heating system bypass valve.

Check tha t t he radiators are correctly balanced.

Noisy boiler operation

Check the flow rate through the boiler at full ga s rate by mea suring the t emperature

rise across the bo iler. If the tempe rature rise is greate r than 8° C, then increase

the pump speed.

Check the level of w ater in the F &E cistern an d t he w orking hea d on the bo iler.

Check and vent the system if necessary.

Noise w hen hot wa ter tap is opened

If the plate hea t exchanger pump is noisy when t he hot wa ter tap is opened, then

check the level of wa ter in the F &E cistern and vent the pump if necessary.Water hamm er - loose pipew ork and/or ta p w ashers.

2. Causes of ‘Unsatisfactory Hot Water Service’

Check that the BoilerMate is full of water i.e. level of water in the F &E cistern is

correct w hen system is cold.

Check bo iler thermosta t - this should be set a t ma ximum.

Check tha t the boiler flow temperature is adeq uate w hen it stops fi ring. Boilers

should provide a flow temperature of 82 ± 3°C but temperatures as low as 76°C will

allow the BoilerMate 2000 to provide a sa tisfacto ry performance.

Check tha t the store is charging to a t least 75°C.

Check that the hot water plate heat exchanger pump stops and starts when thehot w ater tap is opened a nd closed.

Check tha t the plate heat exchang er pump is set at maximum speed.

Check that t he space heating and hot w ater load is not g reater than the b oiler output

and tha t the BoilerMate 2000 model is suita ble for the type o f dwelling.

If all the above checks are satisfactory then it is possible that the performance of

the hea t exchang er is impa ired by sca le. In this case the ho t water flow rate w ill benoticeably less than the cold w ater flow rate. Replace with a factory exchange unit

and re-check hot w ater performance.

3. Causes of ‘Unsatisfactory Space Heating’

Check the boiler thermostat - this should beset at maximum.

Check tha t t he bo iler flow temperature b efore

it is switched off by its ow n internal thermosta t

or the store sensor is ad eq uate - it should not

be less tha n 80°C.

Check the operation and the sett ings of

the heat ing programmer and the room

thermostat.

Check that the heating system pump is

circulating the w ater to the radiat or circuit.

If some rooms a re not being hea ted properly,then b alance the system/check the op eration

of the thermosta tic rad iator valves (if fit ted ).

Overflow from Feed and Expansion Cistern

Check tha t the controlled level of wa ter in thecistern is no high er tha n necessa ry. Adjust

if required.

The ACB can be used to est ab lish/chec k

the operating and set temperatures of the

appliance as well as identify faults on anyof the 3 sensors. This is done b y operat ing

switches SW1 and SW2 as show n op posite and

read ing th e LED display. (See pag e 27)

Store T1, PHE T2, an d DHW T3 ind ica te thecurrent value being read by the store, PHEan d DHWsen sors respect ively. The loca tion

of the sensors is shown in the d iagram shown

oppo site/below.

T1 ON and T1 OFF show the sto re temperature

set points which are automatically reset oneach boiler cycle to match the temperature

produced by the bo iler.

T1 ON show s the t emperature at wh ich the

store will call for heat , i.e signal the boiler to fi re.

T2 OFF shows the t emperature at wh ich thestore will be satisfied, i.e signal the boiler to

switch off.

POWERFLUSHING/CLEANING OF THE HEATINGSYSTEM

If it is proposed to ‘powerflush’ the heating

system we would recommend that the

BoilerMate appliance is isolated from the

hea ting system being cleaned. Failure to do

this could seriously damage the appliance.

When ca rrying o ut the w ork always comp ly

fully with the manufacturers instructions forthe pow erflushing equipment being used.

If in a ny doub t p lease consult our Technical

The pressure loss throug h a flow regulat or

at the designated flow rate is about 1.8 bar.

Therefore for the fl ow regulato r to cont rol theflow rate at pre-set level, the inlet pressure must

be g reate r than 1.8 ba r. If the inlet pressure

is lower, the flow rate will be correspondingly

less than the pre-set va lues.

The ma ximum eq uivalent pipe leng ths fromthe ma nifold to the te rminal fi tting s can be

2 Inhibitor (Corrosion & scale protectionof primary heating circuit)

G U I D A N C E N O T E S

3 Scale protect ion

(Domestic hot water service)

On filling the heating system and before the boiler is fired up, it is important to ensure the

system water is treated with a suitable corrosion inhibitor, in accordance with the boiler

manufacturer’s instructions.

Since the concentration of inhibitor present in a system can become diluted, for a number of

different reasons, the system should be checked annually and re-treated as required, or after

every full or partial drain-down. A water treatment manufacturer’s test kit

may be used to check the correct concentration of inhibitor in the system.

Where recommended by a boiler manufacturer, a ‘physical corrosion

protection device’ may be fitted in the primary pipework in accordance

with the boiler manufacturer’s instructions.

The Benchmark log book should be completed indicating the date and

details of any of the above products added and a permanent label

should be fixed to the system in a prominent location.

Where a combi boiler and/or a hot water storage vessel is installed in areas where the mains

water can exceed 200ppm Total Hardness (as defined by BS 7593: 1993 Table 2) a scale

reduction device should be installed, in accordance with the boiler manufacturer’s instructions.

The levels of water hardness may be measured using a water hardness test kit.

BUILDING REGULATIONS

Completion of the BENCHMARK log book requires that the ‘competent person’ undertaking the

installation and commissioning provide information relating to Cleaning, Inhibitor and Scale Protection.

This will demonstrate that the work complies with the requirements of the appropriate Building

Regulations.
