0" MIN. CLEARANCE
With standard furnace discharge outlet, do not install closer
than 4 inches to intersecting wall.
Choose a location for the thermostat (optional) about 5
feet above the floor on an inside wall. The thermostat wire
supplied with your furnace is 20 feet long, which should be
enough to run up through the attic so the thermostat can
be a maximum of 16 feet from the furnace measured in a
straight line, or approximately 12 feet from the furnace if the
wire is run under the floor. The thermostat should be sensing
average room temperature, avoid the following:
HOT SPOTS:
Concealed pipes or ducts
Fireplaces
Registers
TV sets
Radios
Lamps
Direct sunlight
Kitchen
After picking a location that meets the requirements,
check the walls, attic and roof to make sure there are no
obstructions such as pipes, electric wiring, etc., which could
interfere with the installation of the furnace or vent pipe. If
required, move them or pick a new location.

WARNING: Danger of property damage, bodily
injury or loss of life. Do not install furnace in any area
where oxygen is in use.
Combustion & Ventilation Air
WARNING: Danger of property damage, bodily
injury or loss of life. The furnace and any other fuel-
burning appliances must be provided with enough fresh
air for proper combustion and ventilation of flue gases.
Most homes will require that outside air be supplied into
the heated area.
The high cost of energy for home heating has brought
about new materials and methods used to construct or
remodel most current homes. The improved construction
and additional insulation has reduced the heat loss and
made these homes much tighter around windows and
doors so that infiltrated air is minimal. This creates a
problem to supply combustion and ventilation air for
gas-fired or other fuel burning appliances. Any use of
appliances that pull air out of the house (clothes dryers,
exhaust fans, fireplaces, etc.) increases this problem and
appliances could be starving for air.
In addition, these energy measures mean that your home will
retain more water vapor or a higher relative humidity.
