Recommended Installation Positions
NOTE: Alternate “vertical” piping connections can not be used
when an upflow furnace is installed with supply air discharging to
the right, or when a counterflow furnace is installed with supply air
discharging to the left. In either case, use the standard flue and
combustion air piping connections.
ALTERNATE E LECTRICAL AND G AS L INE CONNECTIONS
This furnace has provisions allowing for electrical and gas line con-
nections through either side panel. In horizontal applications the
connections can be made either through the “top” or “bottom” of
the furnace.
DRAIN P AN
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
Refer to Horizontal Applications and Conditions - Drain Trap and

This furnace is shipped from the factory configured for natural gas
up to 10,000 ft. altitude. Propane conversions require the proper
LP kit to compensate for the energy content difference be-
tween natural and propane gas.
LP kits include a manifold assembly, including an LP gas
valve, orifices and LP burners.

WARNING
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 condensation takes place.
Because of the relatively low flue gas temperature and water con-
densation 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 fac-
tory built or masonry chimney except when used as a pathway for
PVC as described later in this section. Never common vent this
appliance with another appliance 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.
