Separated Combustion Propeller
Fan Gas Unit Heaters
Model GAND/GAPD
The Trane separated combustion
propeller fan gas unit heaters can
yield higher seasonal efficiencies. A
power venting system draws in a
controlled amount of outdoor air for
combustion and exhausts flue
products from the building. The
burners, pilot and flue system are
totally enclosed within the unit,
effectively isolating the entire
combustion process from the dust,
humidity and chemicals in the
heater’s surrounding environment.
