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 di-
rectly to the outdoors or spaces open to the outdoors such as
attics or crawl spaces.
I NSTALLATION P OSITIONS
This furnace may be installed in an upright position or hori-
zontal 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 require-
ments and number of required ductwork connections. Refer
to “Recommended Installation Positions” figure for appropri-
ate installation positions, ductwork connections, and resulting
airflow arrangements.

WARNING
CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each
appliance connected to the venting system being placed
into operation could result in carbon monoxide poisoning or
death.
The following steps shall be followed for each appliance
connected to the venting system being placed into
operation, while all other appliances connected to the
venting system are not in operation:
1) Seal any unused openings in the venting system.
2) Inspect the venting system for proper size and horizontal
pitch, as required in the National Fuel Gas Code, ANSI
Z223.1/NFPA 54 or the Natural Gas and Propane
Installation Code, CSA B149.1 and these instructions.
Determine that there is no blockage or restriction,
leakage, corrosion and other deficiencies which could
cause an unsafe condition.
3) As far as practical, close all building doors and windows
and all doors between the space in which the
appliance(s) connected to the venting system are located
and other spaces of the building.
4) Close fireplace dampers.
5) Turn on clothes dryers and any appliance not connected
to the venting system. Turn on any exhaust fans, such as
range hoods and bathroom exhausts, so they are
operating at maximum speed. Do not operate a summer
exhaust fan.
6) Follow the lighting instructions. Place the appliance being
inspected into operation. Adjust the thermostat so
appliance is operating continuously.
7) Test for spillage from draft hood equipped appliances at
the draft hood relief opening after 5 minutes of main
burner operation. Use the flame of a match or candle.
8) If improper venting is observed during any of the above
tests, the venting system must be corrected in
accordance with the National Fuel Gas Code, ANSI
Z223.1/NFPA 54 and/or Natural Gas and Propane
Installation Code, CSA B149.1.
9) After it has been determined that each appliance
connected to the venting system properly vents when
tested as outlined above, return doors, windows, exhaust
fans, fireplace dampers and any other gas-fired burning
appliance to their previous conditions of use.
