Gas Furnace
The A95UH1D / A93UH1D / 95G1UHD / 92G1UHD
Category IV gas furnace is shipped ready for installation
in the upflow or horizontal 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 horizontal or upflow
applications with bottom return air.
The A95UH1D / A93UH1D / 95G1UHD / 92G1UHD can be
installed as either a Direct Vent or a Non-Direct Vent gas
central furnace. When the unit is installed as a Direct Vent
furnace, it is considered a sealed combustion system.
The furnace is equipped for installation in natural gas
applications. A conversion kit (ordered separately) is
required 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 and Figure 3 for applications involving roof
termination.

Safety Information
Improper installation, adjustment, alteration, service
or maintenance can cause property damage, personal
injury or loss of life. Installation and service must be
performed by a licensed professional installer (or
equivalent), service agency or the gas supplier.
WARNING

CAUTION
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.
