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 with each appliance
connected to the venting system placed in operation, while any
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 by the National Fuel Gas Code, ANSI Z223.1 or
the Natural Gas and Propane Installation Code,
CSA B149.1-15 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 shall operate at
maximum speed. Do not operate a summer exhaust fan.
6. Follow the lighting instructions. Place the appliance being
inspected in operation. Adjust thermostat so appliance shall
operate continuously.
7. Test for spillage from draft hood 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 National
Gas and Propane Installation Code CSA B149.1-15.
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 burning appliance to their previous
conditions of use.
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.
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.
