GAS-FIRED, BLOWER MODELS
MODEL HDB
MODEL BDP
Blower unit heaters are designed for both heating and ventilating. All Modine gas-fired unit
heater types can be equipped with blowers, including our Hot Dawg
®
low-profile residential
garage heaters and the Effinity
93
®
. In fact, the Effinity
93
®
is the only high efficiency gas-fired
unit heater in North America with this option available.
These units can be used in a variety of ways:
• Ducting air in from adjacent spaces for ventilation.
• Protecting units from corrosive spaces by mounting them remotely and ducting in warm air.
• Where quietness is important, blower fans are lower-noise and can be ducted, unlike
propeller units.
• Deflector hoods can be used in areas with higher mounting heights.

j 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 ratings requires use of a high altitude kit.
k 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.
l Data taken at 65°F ambient and unit fired at full-rated input. Mounting height as measured from bottom of unit, and without deflector hoods.
