G61MPVT Gas Furnace
The G61MPVT gas furnace is equipped with a two−stage,
variable speed integrated control. This control ensures
compatibility with a thermostat which provides humidity
control. Each G61MPVT is shipped ready for installation
in the upflow, downflow, horizontal left air discharge or
horizontal right air discharge 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 ap-
plications with bottom return air. The bottom panel must
also be removed and discarded in all downflow or horizon-
tal 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.
All G61MPVT models can be installed as a Direct Vent
gas central furnace. G61MPVT−070, −090 and −110 mod-
els can be installed as a Non−Direct Vent gas central fur-
nace.
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.
