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 left. In this case, use the stan-
dard flue and combustion air piping connections
ALTERNATE ELECTRICAL AND GAS LINE
CONNECTIONS
The 80% & 90% furnaces have provisions allowing for elec-
trical and gas line connections through either side panel. In
horizontal applications the connections can be made either
through the "top" or "bottom" of the furnace.
DRAIN PAN (90% FURNACES ONLY)
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 (90% FURNACES ONLY)
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.

Propane Gas and/or High Altitude Installations
WARNING
Possible death, personal injury or property damage may
occur if the correct conversion kits are not installed.
The appropriate kits must be applied to insure safe and
proper furnace operation. All conversions must be per-
formed 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-
pensate for the natural reduction in the density of both the
gas fuel and the combustion air at higher altitude.
Refer to the Accessories Charts in this manual or product
Specification Sheet for a tabular listing of appropriate
manufacturer's kits for propane gas and/or high altitude in-
stallations. The indicated kits must be used to insure safe
and proper furnace operation. All conversions must be per-
formed by a qualified installer, or service agency.
Vent/Flue Pipe and Combustion Air Pipe (90%
Furnaces Only)
WARNING
Failure to follow these instructions can result in bodily
injury or death. Carefully read and follow all instruc-
tions given in this section.
WARNING
Upon completion of the furnace installation, carefully
inspect the entire flue system both inside and outside
the furnace to assure it is properly sealed. Leaks in the
flue system can result in serious personal injury or
death due to exposure to flue products, including car-
bon 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.
Do not use commercially available "no hub connectors"
other than those shipped with this product.
