High Efficiency Propeller
Fan Gas Unit Heaters
Model GHND/GHPD
Trane high efficiency propeller fan
gas unit heaters can achieve annual
fuel savings of 20 to 25 percent or
more over conventional gravity-
vented heaters. Features include a
factory installed flue vent fan and
sealed flue collector that control
combustion and excess air during the
on-cycle. Heated air no longer
escapes through the draft diverted
opening during the off cycle. Energy-
saving intermittent pilot ignition
reduces gas losses. The pilot only
operates when required. Horizontal
power venting allows for side wall
venting, smaller openings and single-
walled vent pipe. These high
efficiency gas fan unit heaters carry a
ten-year non-prorated warranty on
the heat exchanger, flue collector and
burners.

High Efficiency Centrifugal
Fan Gas Unit Heaters
Model GBND/GBPD
The Trane high efficiency centrifugal
fan gas unit heater incorporates the
same features as the high efficiency
propeller unit heater. An
exceptionally balanced centrifugal
blower assembly results in quieter
operation. The high efficiency
centrifugal fan is also well-suited for
high static applications where
ductwork is required. Duct discharge
flanges may be ordered in lieu of
horizontal louvers to accommodate
ductwork. Trane’s high efficiency
centrifugal fan gas unit heater
carries a ten-year non-prorated
warranty on the heat exchanger, flue
collector and burners.
