Failure to replace any heat exchanger gaskets with new
gaskets when any heat exchanger plates or covers are re-
moved could lead to heat exchanger leakage, sooting, and/or
a hazardous condition capable of causing bodily harm.

This furnace should never be operated without an air filter.
Disposable filters should be replaced at least once a year. If
equipped to provide cooling, filters should be replaced a minimum
of twice a year. Permanent filters should be cleaned at least twice
a year.

ALWAYS KEEP MAIN OIL VALVE TURNED OFF IF
BURNER IS SHUT DOWN FOR AN EXTENDED PERIOD OF
TIME.

Step 2—Oil Burner

Contact your service technician for service.

Lubricate burner motor with SAE 10 oil. Once each year, pour 2
teaspoons of oil slowly into each oil cup.

To maintain proper performance, oil burner nozzle must be
replaced once a year.

The procedure for nozzle installation and/or replacement is out-
lined in oil burner instruction manual which came with furnace.
For ease of maintenance, the oiling procedure for burner motor, as
outlined in burner manual, should be performed at this time.

After replacement of nozzle, burner should be adjusted in accor-
dance with Combustion Check section of this instruction.

Step 3—Heat Exchanger and Flue Pipe

Ordinarily, it is not necessary to clean heat exchanger or flue pipe
every year, but it is necessary to have your service technician
check unit before each heating season to determine whether
cleaning or replacement of parts is required.

CLEANING SECONDARY HEAT EXCHANGER TUBES AND
FLUE PIPE ONLY

If cleaning of only the secondary heat exchanger tubes and flue
pipe is necessary, the following steps should be performed:

1. Turn off all oil and electrical supplies upstream of furnace.

If furnace has been in operation, some surfaces may be hot.
Allow time for unit to cool down.

2. Disconnect flue pipe.

3. For access to cleanout ports, remove blower door and filter.

The 2 cleanout ports are located in blower compartment. They
protrude through the partition and are located on the left and
right of flue pipe. (See Fig. 2.)

4. Unscrew wing clamp nuts and remove cleanout port covers.

This allows access to tubes. (See Fig. 2.)

5. Clean secondary tubes and flue pipe with a stiff brush and

vacuum cleaner.

6. Before reinstalling cleanout port covers, the gasket on each

cover MUST be replaced. Use cleanout port gasket kit Part
No. 20196201.

7. Reinstall covers and tighten in place making sure that covers

are properly seated over ports and gasket has sealed opening.
(See Fig. 3.)

Failure to replace cleanout port cover gaskets, failure to
properly seat covers over ports, and/or failure to securely
tighten wing nuts could lead to flue gas leakage. This could
lead to furnace damage, oil fumes, sooting, and severe bodily
harm.

8. Reconnect flue pipe.

9. Reinstall filter and blower door.

10. Turn on power to unit and readjust burner for proper opera-

tion. Inspect cleanout ports and flue connection to make sure
there are no leaks.

CLEANING BOTH PRIMARY AND SECONDARY HEAT EX-
CHANGERS

If a more thorough cleaning is required (both primary and
secondary heat exchanger sections), the following steps should be
performed:

1. Turn off all oil and electrical supplies upstream of furnace.

If furnace has been in operation, some surfaces may be hot.
Allow time for unit to cool down.

2. Remove blower door.
