If this furnace is to be installed in the same space with
other gas appliances, such as a water heater, ensure there
is an adequate supply of combustion and ventilation air
for the other appliances. Refer to the latest edition of the
National Fuel Gas Code NFPA 54/ANSI Z223.1 or CAN/
CSA B149.1-15 Installation Codes or applicable provisions
of the local building codes for determining the combustion
air requirements for the appliances.
Most homes will require outside air be supplied to the furnace
area by means of ventilation grilles or ducts connecting
directly to the outdoors or spaces open to the outdoors such
as attics or crawl spaces.

Recommended Installation Positions
This furnace may be installed in an upright position or
horizontal on either the left or right side panel. Do not
install this furnace on its back. For upright upflow furnaces,
return air ductwork may be attached to the side panel(s)
and/or basepan. For horizontal upflow furnaces, return
air ductwork must be attached to the basepan. For both
upright or horizontal counterflow furnaces, return ductwork
must be attached to the basepan (top end of the blower
compartment). NOTE: Ductwork must never be attached to
the back of the furnace. Contact your distributor for proper
airflow requirements and number of required ductwork
connections. Refer to “Recommended Installation Positions”
figure for appropriate installation positions, ductwork
connections, and resulting airflow arrangements.
HORIZONTAL APPLICATIONS &
CONSIDERATIONS
When installing a furnace horizontally, additional
consideration must be given to the following:
Furnace Suspension
If suspending the furnace from rafters or joists, use 3/8”
threaded rod and 2”x2”x1/8” angle iron as shown in the
following diagram.

The length of rod will depend on the application and the
clearances necessary.
If the furnace is installed in a crawl space it must be
suspended from the floor joist or supported by a concrete
pad. Never install the furnace on the ground or allow it to be
exposed to water.
Front Cover Pressure Switch Tube Location
When a furnace is installed horizontally with left side down,
the front cover pressure switch tube must be re-located to
the lower port of the collector box cover.
1. Remove tube from front cover pressure switch and
collector box cover.
2. Remove rubber plug from bottom collector box port
and install on top collector box port.
