GARAGE, WORKSPACE AND OUTBUILDING HEATERS
HOT DAWG™ POWER-EXHAUSTED, GAS-FIRED UNIT HEATER (MODEL HD)• Quiet operation allows your space to be warm
without the distraction of a loud machine runningin the background
• Unit can easily be rotated to allow for convenientright or left side control placement**
• Fuel type: Natural or propane gas
• Low-profile, lightweight design easily installs1” from ceiling with only two angle brackets*
• Casing construction made of heavy gauge metal
• Full 10-year warranty on heat exchanger
HOT DAWG™ H2O LOW PROFILE HOT WATER UNIT HEATER (MODEL HHD)• Low-profile design with flexible mounting options (parallel, perpendicular or recessed
between joists) allows for horizontal or vertical air delivery
• No external moving parts - twin centrifugal blowers keep all moving parts inside the cabinet
• Side panel air inlet opening have factory installed finger guards
• Constructed of heavy gauge steel for long lasting durability
• Includes two mounting brackets with vibration isolators to reduce noise and vibration
• Internal coil can handle water pressures up to 150 PSI and temperatures up to 200°F

• Permanently-lubricated motor formaintenance-free dependability
• Single- or two-stage controls available
• Direct spark ignition for reliable andconsistent ignition
• 100% shut-off with continuous retry to allowfor safe ignition in the event the unit doesn’tlight on the first try
• Factory installed finger proof fan guards
• Blower models (HDB) available
HOT DAWG™ SEPARATED COMBUSTION GAS-FIRED UNIT HEATER (MODEL HDS)Experience the same great features as the HD, with these added benefits:
• Blower models (HDB) available
• Draws fresh air from outside, ensuringdust, dirt or fumes do not affect durabilityor performance
• Factory assembled, certified separatedcombustion. No add-ons needed allow foran easier and quicker installation providinggreater durability and reduced maintenance
* Sizing data for sample only. Consult a qualified installer for the actual requirements for your building.

Ratings shown are for elevations up to 2,000 ft. For elevations above 2,000 feet, ratings should be reduced at the rate of 4% for each 1,000 feet above sea level. (In Canada see rating plate) Reduction of rating requires use of a high altitude kit.
Data taken at 55°F air temperature rise. At 65°F ambient and unit fired at full-rated input. Mounting height as measured from bottom of unit, and without deflector hoods.
