FLUE DISCHARGE
Visually inspect the discharge outlet periodically to ensure soot and dirt
buildup is not excessive. If necessary, clean the discharge outlet to
maintain adequate combustion air discharge.
The manufacturer recommends that the furnace system is inspected
once a year by a qualified service technician.
CLEANING FLUE PASSAGES AND HEATING ELE-
MENTS
With proper combustion adjustment, the heat exchanger of a gas-fired
furnace seldom requires cleaning. If the heat exchanger becomes
sooted, cleaning must be performed by a qualified service agency.
REGISTERS
Supply air and return air registers must be open when the unit is in
operation. Make sure that furniture does not block airflow in or out of the
registers.
TROUBLESHOOTING
Before calling a service technician, do the following:
1. Check the thermostat to ensure it is set to the HEAT or COOL posi-
tion.
2. Check the thermostat for lint and dust, for example.
3. Check fuses or circuit breakers.
4. Check filters for excessive dust accumulation and/or restriction.

ENERGY EFFICIENCY
The following are some tips for increasing the energy efficiency of your
unit:
• Do not heat or cool unused areas. Reduce supply and return air-
flow to a minimum in areas that are not living spaces, for exam-
ple, storage rooms, garages, and basements.
• Do not adjust your thermostat unnecessarily. Increasing or
decreasing the temperature setting on your thermostat does not
make your system heat or cool any faster. Set your thermostat to
a comfortable setting and only adjust it when required.
• Do not restrict air circulation. If the placement of items such as
furniture or rugs interferes with air vents, your system has to work
harder to reach selected temperatures. This requires more
energy, resulting in higher costs.
• Do not heat or cool your home when you are away. If you are
going to be away from home for a period, for example, a day or
more, adjust your thermostat accordingly. Be aware that it takes
the system some time to reach selected temperatures on your
return home. This does not occur immediately.
• Do not locate lamps or other heat producing appliances such as
radios, television sets, and heaters near your thermostat. The
heat from these items gives your thermostat false information
about room temperature.
• Select a comfortable thermostat setting, but remember that
selecting a moderate temperature saves energy.
• Turn on your kitchen exhaust fan when cooking and turn on your
bathroom exhaust fan when showering. Make sure your clothes
dryer is properly vented. Otherwise, excess heat and humidity
can be created, causing your AC system to run for longer.
• Set your thermostat a few degrees lower than normal several
hours before entertaining a large group of people in a relatively
small area. People give off a considerable amount of heat and
moisture in a closed area.
• Keep drapes and venetian blinds closed when practical, because
they provide insulation against heat loss or heat gain.
• Contact a qualified service technician to repair or make adjust-
ments to your system. They are trained to perform this service.
