G61MP Gas Furnace
The G61MP category IV gas furnace is shipped ready for
installation in the upflow, downflow, horizontal left air dis-
charge or horizontal right air discharge position. The fur-
nace is shipped with the bottom panel in place. The bot-
tom panel must be removed if the unit is to be installed in
upflow applications with bottom return air. The bottom
panel must also be removed and discarded in all downflow
or horizontal applications.
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.
The G61MP can be installed as either a Direct Vent or a
Non−Direct Vent gas central furnace.
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.
