Todays homes are tightly constructed to seal them rom dra ts that are uncom ortable and wasteenergy. Contemporary li estyles demand abundant hot water supplies or radiant heating, largeamounts o domestic hot water, pools, Jacuzzis, towel warmers and or snow melting applicationsto minimize the hazards o winter. And with todays rising energy costs, consumers are consideringhigh e ciency condensing boilers, especially those that meet the ederal Energy Star requirements.To meet these greater per ormance demands, new high e ciency condensing boilers have been

developed to deal with variable operating temperatures and fow rates, requent cold starts and quick response between space heating demands and demands or domestic hot water. This is where theBimini ts the bill.New technologies in materials and control systemsEmploying the latest cast aluminum metallurgy andadvanced burner control technologies, CROWNs BiminiSeries is more e cient than conventional boilers, and achievese ciencies up to 95.4% A.F.U.E.Once morning warm-up is complete, heating demand during therest o the day may only call or a small percentage o thetotal boiler output. Typically, boilers operate at one ring rate,and turn on and o to provide the desired amount o heat.The Bimini utilizes a microprocessor control system tomonitor heating needs and to automatically adjust the

ring rate to minimize the amount o uel consumed.Regulating the boiler to partial loads requires a burner witha high turndown capability. The Biminis modulating controlsystem tracks the demand or space heat and domestic hot

water, and senses the supply water temperature and outdoortemperature to precisely adjust heat output.

Pre-mix burner The Bimini is equipped with a pre-mix, stainless steel burnersystem which meters the precise amount o uel and air tooptimize combustion at any ring rate. An important bene tis that the resulting combustion process is clean burning and

very quiet. Aluminum heat exchangersBimini eatures low-mass, cast aluminum heat exchangers superiorcorrosion resistancean important attribute or

condensing boilers. Aluminum can be cast intointricate designs that improve heat trans er e ciency.Flow paths on both the combustion side and the waterside are engineered to optimize e ciency.

Why a condensing boiler Condensing design is necessary in a very high e ciencyboiler. When the boiler is operating at maximum

e iciency the exhaust temperatures become so low that water vapor in the exhaust condenses. The boiler mustbe designed to drain away this liquid.

Sealed combustion with multiple venting optionsBiminis sealed combustion design isolates the combustionprocess in your boiler rom the air in your home. Thissaves energy dollars by using combustion air rom outside,rather than room air youve already paid to heat. Verticalor horizontal venting is available to accommodate variousinstallations.

Bimini is ef cient in many waysBimini uses less foor space than other similarly sizedboilers, and the smaller sizes can be hung on the wall.Bimini is lighter in weight than conventional boilers.The Bimini is designed or easy installation. Water andgas piping are conveniently located, and electricalcomponents are prewired. A terminal strip is provided

or quick and easy eld wiring.Domestic Hot Water Priority Bimini is designed to partner with the Mega-StorIndirect Water Heater to provide domestic hot watere ciently.

Withtodays highenergy costs, owners

o commercial properties want boilers that provideoptimum com ort at the lowestcost. So, they are choosing the BiminiCommercial with thermal e ciency ratingsup to 93.1%.

Maximum e ciency is achieved by modulating the boilersoperation to meet the changing heat requirements over thecourse o the day. To handle large acilities, multiple Biminiboilers can be installed.

The Bimini is ruggedly built to provide years o service. It usesthe latest o microprocessor controls or e ciency and sa ety.

Vent length can reach up to 100 eet. For the BWC300,concentric polypropylene venting is available which means onlya single terminal outside or a cleaner look.

The Bimini can be installed on non-carpeted combustible sur aces,and is approved or installation in a closet.

For ease o installation, it is actory assembled, pre-wired and packaged.
