NOTE
: Before you start, TURN OFF all electrical
power to unit and turn thermostat to OFF.
Filters
A filter is supplied with the furnace. It is NECESSARY
THAT ALL FURNACES BE EQUIPPED WITH A
FILTER.
If a different type of filter is used, it must be an equiva-
lent high airflow capacity.
Keeping Filters Clean
As a homeowner, this is your most important responsi-
bility. A dirty filter reduces the efficiency of your sys-
tem, causes erratic performance of controls, and could
result in damage to the motor or heat exchanger.
1. Inspect filters at regular intervals depending upon dirt
conditions. For new homes, check filters every week
for 4 consecutive weeks. In all cases, inspect your
filters at least every 3 to 4 weeks when the system is
in constant operation. Replace or clean filter at least
at the beginning of each season (heating & cooling)
and thereafter as needed.
2. If the permanent filter supplied with the unit be-
comes dirty, it can be cleaned with cold water and
soap.
Be sure that the filter is thoroughly dry before installing
back into the furnace.
Lubricating Motors
Direct drive motor and blower assemblies are factory
lubricated and normally do not require oiling. If oiling
is required, lubrication of the blower motor is to be per-
formed only by a qualified service technician.
Here is A Handy Checklist
If your furnace fails to operate properly, first check the
following. It may save you the cost of a service call:
1. Is your room thermostat set correctly? On heating/
cooling systems, the thermostat should be set to
HEAT or COOL mode and the fan set to AUTO or
ON (continuous fan operation).
2. Are the electrical power and oil supplies both on?
3. Are the filters clean?
4. Is the ignition control on the burner operational
(not in lockout)? The red button on top of the
control must be depressed for 3 sec in order to reset
the control.
If the answer to these questions is YES and the furnace
still does not operate properly, call your authorized
dealer for service.
WARNING
Never operate unit without a filter or with fil-
ter access door removed. Failure to adhere
to this warning could lead to a hazardous
condition which could lead to equipment
damage and bodily harm.
