FURNACE USER MAINTENANCE

Every time the filters are changed the following items should be visually
inspected:

• Check roof jack assembly for blockage or leakage.

• Check all components to be sure they are in good condition and

that there are no obvious signs of deterioration.

• Check the evaporator coil drain lines to make sure there are no

cracks or leaks.

• Check for dirt or lint on any surfaces or on components. Do not try

to clean any of the surfaces or components. Cleaning of the fur-
nace and its components must be done by a qualified service pro-
fessional.

If, during the inspection of your furnace, you find any of the following
conditions:

• Excessive amounts of dust and lint on components.

• Damaged or deteriorated components or surfaces.

• Leaks or blockage in the vent pipe passages.

• Water on any surface inside or outside of the furnace.

Do not operate the furnace, and call a certified dealer / servicing con-
tractor to check and / or clean your furnace, or for more information if
you have questions about the operation of your furnace.

If all components appear to be in good operating condition, replace the
front panels. Follow the operating instructions to place the furnace in
operation.

Air Filters

Dirty filters greatly restrict the flow of air and may cause damage to the
moving parts of the furnace. If the filters become clogged the heat
exchangers and blower motor could overheat resulting in a potentially
dangerous situation.

The filters should be checked every 3 months (DO NOT USE PLEATED
FILTER in this furnace). On new construction, check the filters every
week for the first four weeks and every three weeks after that, espe-
cially if the indoor fan is running continuously. When replacing the fil-
ter(s) you must use filters that are the same size and type as those in
the furnace (2 - 16 x 20 x1).

Removing Filters

Internally Mounted Air Filters

The air filter is in a rack that is attached to the door of the furnace.
To remove the filter you must do the following:

1. Before proceeding, be sure the area is well ventilated. Follow

instruction “To turn off the appliance”. Check all metal parts and sur-
faces to be sure they have cooled to room temperature before you
begin.

2. Remove the filter door.

3. Remove the air filter by sliding it down the track. The air filter will

slide out of the rack.

4. Replace throw away filter(s) with the same size new filter(s). Throw

away filter(s) may be replaced with cleanable filter(s) at this time.
Cleanable filter(s) may be cleaned as described in the manufacturer
instructions or as described in these instructions.

To replace the filter after cleaning you must do the following:

1. Slide filter into place. If the filter has been cleaned, make sure it is

dry before re-installing it.

2. Replace the door or cover panel.

3. Make sure the door snaps into the retaining clips.

4. Follow the Operating Instructions to place the furnace back in oper-

ation.

 WARNING

Should overheating occur, or the gas valve fail to shut off, turn the
external manual gas valve in the gas supply line to the furnace to the
“off” position and let the furnace cool off before shutting off the electri-
cal power supply. Refer to Figure 5.

 WARNING

Before proceeding, be sure the area is well ventilated. Turn the ther-
mostat OFF. If the blower is running, wait until it stops automatically.
Turn OFF the gas and electrical power supplies to the furnace. Check
all metal parts and surfaces to be sure they have cooled to room tem-
perature before you begin.
