Thermostat Operation (when you have heating only)
The thermostat is the only control you’ll need to set, as the
furnace is completely automatic. Just set the temperature
to the desired comfort level.
Thermostat Operation (when you have heating and
cooling)
There are two switches located on the thermostat. One
switch controls the heating and cooling functions. The other
switch is for “FAN” operation, either continuous or automatic.
On the thermostat is the temperature range for the heating
temperature and the cooling temperature desired.
To put the system into operation, push the switch to either
“HEAT” or “COOL” position.
After you have chosen the type of operation you desire,
move the thermostat dial or lever to select the temperature
you would like the system to maintain.
Fan Operation
You may wish to increase your comfort by setting your
system for continuous air circulation of the indoor air. The
fan switch on the thermostat permits you to do this (see
Figure 1).
With the switch in the “ON” position the fan will operate
continuously. “AUTO” position gives fan operation only when
the unit is in either heating or cooling.
Maintenance Of Your Furnace
There are routine maintenance steps you should take to
keep your unit operating efciently. This will assure longer
life, lower operating costs, and fewer service calls. The
steps given in this publication are easy to follow and are
not time consuming. Certain service and maintenance
procedures require the skill of a trained service person who
has specialized tools and training for their use. Please call
your dealer for service. Personal injury can result if you are
not qualied to do this work.
Cleaning/Replacing the Filter
It is very important to clean or replace the air lter regularly.
A dirty air lter can sharply increase the operational costs
of your unit...in some cases it can double the cost. The air
lter should be inspected at least every 6 weeks and
cleaned or replaced as required.

What to do if your unit is not heating properly
If your unit is operating but fails to provide complete comfort,
check the following before calling for service:
1. Be sure the thermostat setting is correct.

Do not block supply registers or return grilles with
furniture or rugs.
And if you also have cooling...
4. Keep surface of the outdoor coil free from dirt, lint, paper,
or leaves.
5. Check and clean indoor coil if necessary. (This check
should be made at the start of each cooling season by
your service technician.)

1. Be sure the main switch that supplies power to the unit
is in the “ON” position.
2. Replace any burned-out fuses or reset circuit breakers.

Temperature Control
There are many types and styles of thermostats. Yours may
look different from the one pictured in Figure 1, depending
on the type of thermostat and whether cooling was installed
with the system. However, almost all thermostats perform
the same basic functions described in the following section.
Always turn off the power to your furnace before
removing the doors or lters. Failure to turn the power
off could result in property damage, personal injury, or
death.
