G43UF Gas Furnace
The G43UF Category IV gas furnace is shipped ready for
installation in the upflow position. The furnace is shipped
with the bottom panel in place. The bottom panel must be
removed if the unit is to be installed in upflow applications
with bottom return air.
The G43UF can be installed as either a Direct Vent or a
Non−Direct Vent gas central furnace.
The furnace is equipped for installation in natural gas ap-
plications. A conversion kit (ordered separately) is re-
quired for use in propane/LP gas applications.
NOTE − In Direct Vent installations, combustion air is taken
from outdoors and flue gases are discharged outdoors. In
Non−Direct Vent installations, combustion air is taken from
indoors and flue gases are discharged outdoors. See figure
2 for applications involving roof termination.

DANGER
Danger of explosion.
There are circumstances in which odorant used with
LP/propane gas can lose its scent. In case of a leak,
LP/propane gas will settle close to the floor and may
be difficult to smell. An LP/propane leak detector
should be installed in all LP applications.
Check equipment for shipping damage. If you find any
damage, immediately contact the last carrier.
The following items may also be ordered separately:
1 − Thermostat
1 − Propane/LP changeover kit
