MAINTENANCE

LUBRICATION

No lubrication is required for either the burner or the
blower motor.  Both are permanently lubricated.

INSPECT AIR FILTER

Washable air filters are supplied with each furnace.
Washable filters should not be replaced with disposable
type.  Clean filters before each heating season begins.
It is recommended that filters also be cleaned at least
twice during the heating season.

Be sure the new filters are set securely in the filter rack
so there can be no leakage around them.  (See
instructions on inside of blower compartment door.)

FINAL INSPECTION AND TEST

Final inspection and test of an installation shall be
made to determine that the work has been done in full
accordance with regulations and according to the
highest standards for safety, performance and
appearance.  Such an inspection and test should
indicate the following as a minimum:

1. Determine that all parts of the oil storage and

circulating system, including tank, piping and
burner, are free from oil leaks.  Be sure that no oil
discharges from the nozzle when burner is not
operating.

2. Be sure that the suction line and pump have been

entirely vented of air so that the burner has
instantaneous oil shutoff at the nozzle and so that
the pump operates without an air noise.

3. Check the flame adjustment to determine that the

flame is clear, quiet, free of odor and oil nozzle is
of proper size for the furnace.

4. Test operation of burner by operating the

thermostat.  First, set the thermostat above room
temperature.  Burner should start.  Second, set
thermostat below room temperature.  Burner will
stop.

5. Check operation of burner primary control in

accordance with manufacturer’s instructions
included with the control.  Following is the method
we recommend in checking the safety switch in
this primary control.

A. Flame Failure  –  Simulate by shutting off oil

supply manual valve while burner is on.
Within 9 seconds the control will shut the
burner down and flash a diagnostic code of
1/2 second on / 1/2 second off.  Ignition and
motor stop and oil valve closes

B. Ignition Failure  –  Test by closing oil supply

while burner is off.  Run through starting
procedure.  The primary control will attempt
three trials for ignition.  After three attempts,
the control will lockout.

C. Power Failure  –  Turn off power supply

while burner is on.  When burner goes out,
restore power and burner will restart.

D. If operation is not as described, check wiring

and installation first.  If trouble appears to be
in the control circuit, replace the flame
detector.  If trouble still persists, refer to
“Common Causes of Trouble” section on
page 26.

SERVICE HINTS

Preventive maintenance is the best way to avoid
unnecessary expense, inconvenience, and retain
operating efficiency of your furnace.  It is advisable to
have your heating system and burner inspected at
periodic intervals by a qualified serviceman.  If trouble
develops, follow these simple checks before calling the
serviceman.

1. Make sure there is oil in tank and valve is open.

2. Make sure thermostat is set above room

temperature.

3. Make sure electrical supply to furnace is on and

fuses are not blown or circuit breakers tripped.

4. Reset safety switch of burner primary control.

         CAUTION

Reset three (3) times only.  More than three
resets can cause excessive oil to be pumped
into combustion chamber which could result in
explosion upon ignition.

5. Press thermal protector button of burner motor.

6. Make sure air filters are in place and are clean.

7. Make sure all air openings in furnace, all

ventilation and combustion air openings, all return
air grilles, and all warm air registers are
unobstructed and open.
