CAUTION
!
The ability to properly perform maintenance on
this equipment requires certain mechanical skills
and tools. If you are at all uncertain, contact your
dealer for qualified maintenance and service.
The operation and care of your unit is simple and easy. By fol-
lowing these operating and maintenance procedures, you can
expect to receive better, longer, and more reliable service from
your new appliance.
HERE ARE A FEW DO'S AND DO NOT'S
• DO become familiar with the instructions.
• DO use filters. Check them periodically and make sure that
they are clean.
• DO check to see that your home has adequate insulation,
weatherstripping, caulking, and storm windows. Eliminating in-
filtration of outside air and drafts can save up to 40% of your
fuel bill.
• DO NOT waste fuel by setting your thermostat too high. En-
ergy conservation experts recommend daytime thermostat set-
ting of 68 ° F, with a lower setting at night.
• DO NOT turn off the furnace when you expect to be away
for more than a day. Instead, lower the thermostat setting by a
few degrees. You can then restore normal comfort level quickly
and save fuel too.
• DO NOT block registers with furniture.
• DO NOT put a lamp, TV, or radio too near your thermostat.
This will cause it to give a false reading.
Here's How Your Heating System Works
The furnace operates automatically. It is controlled by a ther-
mostat which you set at the temperature most comfortable to
you. When the inside temperature drops below this setting,
your thermostat will turn on the heating system.
When the thermostat calls for heat, power from the transformer
energizes the fan control board. The fan control energizes the
ignition control. The ignition control will light the burner au-
tomatically.
The electronic fan control will automatically turn on the
blower after 30 sec. Fan on control is not adjustable. The air
moved over the heat exchanger by the blower is warmed and
passes through the ducts to the room registers.
When the thermostat is satisfied, the circuit is de-energized and
the primary control shuts off the burner. The blower continues
to run until the selectable fan off time period has expired.
The heat sensing switch performs as the furnace high temper-
ature limit switch. If the furnace overheats for any reason, the
limit switch opens, breaking the circuit to the burner. The
blower motor will be energized and as the unit cools the limit
switch will close. This will relight the burner but unless the
overheating condition is corrected, the furnace will continue to
cycle on limit.
This unit is equipped with an interrupted ignition electronic
control. If the main burner does not ignite within 30 sec from
the call for heat, the control will go into lockout. The red button
on top of the control must be depressed for 3 sec in order to
reset the control. The control CANNOT be reset from the room
thermostat.
