Installations must adhere to the clearances to combus-
tible materials to which this furnace has been design
certified. The minimum clearance information for this
furnace is provided on the unit's clearance label. These
clearances must be permanently maintained. Clearances
must also accommodate an installation's gas, electrical,
and drain trap and drain line connections.
NOTE: In addition to the required clearances to combus-

Existing Furnace Removal

NOTE: When an existing furnace is removed from a
venting system serving other appliances, the venting
system may be too large to properly vent the remaining
attached appliances.
The following vent testing procedure is reproduced from
the American National Standard/National Standard of
Canada for Gas-Fired Central Furnaces ANSI Z21.4, CSA-
2.3 latest edition Section 1.23.1.
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 sys-
tem are not in operation:
1. Seal any unused openings in the venting system;
2. Inspect the venting system for proper size and hor-
izontal 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 instruc-
tions. Determine that there is no blockage or restric-
tion, leakage, 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
located and other spaces of the building.
4. Close fireplace dampers.
5. Turn on clothes dryers and any appliance not connect-
ed 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
If resizing is required on any portion of the venting sys-
tem, use the appropriate table in Appendix G in the latest
edition of the National Fuel Gas Code ANSI Z223.1 and/or
CSA B149.1-15 Installation Codes.

Thermostat Location

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 influenced 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.
Combustion & Ventilation Air Requirements
T
O AVOID PROPERTY DAMAGE
SUFFICIENT FRESH AIR FOR PROPER COMBUSTION AND VENTILATION OF
FLUE GASES MUST BE SUPPLIED
SUPPLIED INTO THE FURNACE AREA
Improved construction and additional insulation in build-
ings 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 combustion and ventilation
air for gas fired and other fuel burning appliances. Ap-
pliances that pull air out of the house (clothes dryers,
exhaust fans, fireplaces, etc.) increase the problem by
starving appliances of air.
