NOTE: Improperly sized vents can cause the formation of
condensate, combustion gas leakage and spillage, and an
inoperable furnace.
This unit is not a household appliance. It is a complex
self-contained system that requires professional maintenance
and repair. That’s why attempts at do it yourself repairs on an
in-warranty unit may void the remainder of your warranty. Other
than performing the simple maintenance recommended in this
manual, you should not attempt to make any adjustments to
your system.
NOTE: The blower motor bearings are factory lubricated and
under normal operating conditions usually do not require
servicing. Your local servicer can advise you if oiling is required.
Your dealer should be able to take care of any questions or
problems you may have.
Keep your unit looking like new for years.
Clean the enamel finish of your unit with ordinary soap and water.
For stubborn grease spots, use a household detergent. Lacquer
thinner or other synthetic solvents may damage the finish.
Just set the temperature you want.
Set temperatures by using the indicators on the thermostat*
control. After that, your comfort control center (thermostat) will
maintain a constant indoor temperature, regardless of changes
in outdoor temperatures. Read your thermostat manual for
directions on setting the temperatures.
Save energy with an electronic programmable thermostat.
With an electronic programmable thermostat* energy savings is
easy. Just program the thermostat for the temperatures you are
most comfortable with and it will automatically change settings
up to four times a day. Special weekend and vacation schedules
are also easily programmed for comfort and savings. Read your
thermostat manual for programming instructions. If you want
the optimum balance between comfort and the cost of running
your system, we recommend keeping the temperature settings
at 68°F for heating and 78°F for cooling.
Save energy by letting the thermostat do its job. Once you
set the thermostat, keep subsequent adjustments to a minimum.
Adjust it only when a new program is needed.
*Optional accessory
Whenever your house is to be vacant, arrange to have
someone inspect your house for proper temperature. This
is very important in below freezing weather. If for any reason
your unit should fail to operate, damage could result, such
as frozen water pipes.
