90% Furnace Recommended Installation Positions
NOTE: Alternate "vertical" piping connections can not be
used when an upflow 90% furnace is installed with supply
air discharging to the right or when a counterflow furnace is
installed with supply discharging to the left. In this case,
use the standard flue and combustion air piping connec-
tions
Alternate Electrical and Gas Line Connections
Furnaces have provisions allowing for electrical and gas line
connections through either side panel. In horizontal applica-
tions the connections can be made either through the "top"
or "bottom" of the furnace.
Drain Pan
A drain pan must be provided if the furnace is installed above
a conditioned area. The drain pan must cover the entire area
under the furnace (and air conditioning coil if applicable).
Freeze Protection
If the drain trap and drain line will be exposed to tempera-
tures near or below freezing, adequate measures must be
taken to prevent condensate from freezing. NOTE: The use
of insulation and/or heat tape is recommended. Failure to
provide proper condensate drainage can result in property
damage.

MUST BE APPLIED TO INSURE SAFE AND PROPER FURNACE OPERATION.
CONVERSIONS MUST BE PERFORMED BY A QUALIFIED INSTALLER OR SERVICE
AGENCY.
This furnace is shipped from the factory configured for natu-
ral gas at standard altitude. Propane gas installations re-
quire an orifice change to compensate for the energy con-
tent difference between natural and propane gas.
High altitude installations may require both a pressure switch
and an orifice change. These changes are necessary to com-

PON COMPLETION OF THE FURNACE INSTALLATION, CAREFULLY INSPECT THE
ENTIRE FLUE SYSTEM BOTH INSIDE AND OUTSIDE THE FURNACE TO ASSURE IT
IS PROPERLY SEALED.
PERSONAL INJURY OR DEATH DUE TO EXPOSURE TO FLUE PRODUCTS,
INCLUDING CARBON MONOXIDE.
A condensing gas furnace achieves its high level of efficiency
by extracting almost all of the heat from the products of
combustion and cooling them to the point where condensa-
tion takes place. Because of the relatively low flue gas tem-
perature and water condensation requirements, PVC pipe
is used as venting material.
This furnace must not be connected to Type B, BW, or L
vent or vent connector, and must not be vented into any
portion of a factory built or masonry chimney except when
used as a pathway for PVC as described later in this sec-
tion. Never common vent this appliance with another appli-
ance or use a vent which is used by a solid fuel appliance.
It is the responsibility of the installer to follow the manufac-
turers' recommendations and to verify that all vent/flue pip-
ing and connectors are compatible with furnace flue prod-
ucts. Additionally, it is the responsibility of the installer to
