2. Inspect the venting system for proper size and horizon-
tal pitch, as required by the National Fuel Gas Code,
ANSI Z223.1 or the Natural Gas and Propane Installa-
tion Code, CSA B149.1-05 and these instructions. De-
termine that there is no blockage or restriction, leak-
age, corrosion and other deficiencies which could cause
an unsafe condition.
3. As far as practical, close all building doors and win-
dows and all doors between the space in which the
appliance(s) connected to the venting system are lo-
cated 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 op-
eration. 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 accor-
dance with the National Fuel Gas Code ANSI Z223.1/
NFPA 54 and/or National Gas and Propane Installation
Code CSA B149.1-05.
9. After it has been determined that each appliance con-
nected 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.
If resizing is required on any portion of the venting system, use
the appropriate table in Appendix G in the latest edition of the
National Fuel Gas Code ANSI Z223.1 and/or CSA B149.1-05
Installation Codes.

HERMOSTAT
OCATION
The thermostat should be placed approximately five feet from the
floor on a vibration-free, inside wall in an area having good air
circulation. Do not install the thermostat where it may be influ-
enced by any of the following:
•
Drafts, or dead spots behind doors, in corners, or under
cabinets.
•
Hot or cold air from registers.
•
Radiant heat from the sun.
•
Light fixtures or other appliances.
•
Radiant heat from a fireplace.
•
Concealed hot or cold water pipes, or chimneys.
•
Unconditioned areas behind the thermostat, such as
an outside wall.
Consult the instructions packaged with the thermostat for
mounting instructions and further precautions.

INTO
THE
FURNACE
Improved construction and additional insulation in buildings have
reduced heat loss by reducing air infiltration and escape around
doors and windows. These changes have helped in reducing
heating/cooling costs but have created a problem supplying com-
bustion and ventilation air for gas fired and other fuel burning
appliances. Appliances that pull air out of the house (clothes
dryers, exhaust fans, fireplaces, etc.) increase the problem by
starving appliances for air.
House depressurization can cause back drafting or improper com-
bustion of gas-fired appliances, thereby exposing building occu-
pants to gas combustion products that could include carbon mon-
oxide.
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 Installation Codes or appli-
cable 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.

NSTALLATION
OSITIONS
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 connec-
tions. Refer to "Recommended Installation Positions" figure for
appropriate installation positions, ductwork connections, and re-
sulting airflow arrangements.
