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
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 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 combustion 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
combustion of gas-fired appliances, thereby exposing build-
ing occupants to gas combustion products that could include
carbon monoxide.
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 require-
ments for the appliances.
Most homes will require outside air be supplied to the fur-
nace 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.
