: Be sure that the home 

owner knows where the burner reset 
switch is located, and is aware that the 
reset switch is not to be activated more 
than once without a thorough look for the 
cause of the problem, (lack of fuel, etc.). 
Be sure that the homeowner knows 
when to quit trying to start the furnace 
during these conditions and who to call 
for emergency service. 

Other than remembering to arrange for 
the annual professional servicing of the 
furnace by the service or installation con-
tractor, the most important routine ser-
vice performed by the homeowner is to 
maintain the air filter or filters. A dirty 
filter can cause the furnace to over-heat, 
fail to maintain indoor temperature during 
cold weather, increase fuel consumption 
and cause component failure. 

The furnace filter(s) should be inspected, 
cleaned or replaced monthly. The fur-
nace is factory equipped with a semi-
permanent type filter. If the filter is dam-
aged, replace with filters of the same 
size and type.  

During the routine service, inspect the 
general condition of the furnace watching 
for signs of oil leaks in the vicinity of the 
oil burner, soot forming on any external 
part of the furnace, soot forming around 
the joints in the vent pipe, etc. If any of 
these conditions are present, please 
advice your service or installation con-
tractor. 

. 

The heat exchanger should be inspected 
periodically and cleaned if necessary. if 
cleaning is necessary, SHUT OFF 
POWER TO THE FURNACE

 and re-

move the burner. Using a stiff brush with 
a wire handle, brush off scale and soot 
from inside the drum and flue pipe. To 
clean the heat exchanger radiator, re-
move the covers on the front or inner 
front panel, and then loosen the brass 
nuts on the radiator clean-out yoke as-
sembly. Do not remove the brass nuts. 
The yoke assembly, once loosened, may 
be removed to gain access to the heat 
exchanger outer radiator.  

A wire brush can be used to loosen dirt 
and debris on the inside surfaces of the 
radiator. Clean out all accumulated dirt, 
soot and debris with a wire handled 
brush and an industrial vacuum cleaner. 
Replace the clean-out yoke assemblies 
and clean-out covers. 

Most circulating fan motors are perma-
nently lubricated by the motor manufac-
turer. These motors will have no oil 
ports. If the blower motor does contain 
oil ports, under normal operating condi-
tions it will not require oiling for the first 
two years. Oil sparingly; a few drops in 
each oil port with SAE 20 non-detergent 
oil. Oiling is most easily done with a 
"tele-spout" oiler. This oiler has a long 
flexible plastic spout. DO NOT OVER-
LUBRICATE. Excess oil may result in 
premature electric motor failure. 

Inspect the blower fan. Clean it if neces-
sary. 

Oil Burner Maintenance: Follow the in-
structions of the oil burner manufacturer. 
(See oil burner manufacturer's instruc-
tions supplied with furnace). The oil 
burner nozzle should be replaced annu-
ally. We recommend that the oil filter be 
changed on an annual basis. 

The venting system should be cleaned 
and inspected for signs of deterioration. 
Replace pitted or perforated vent pipe 
and fittings. The barometric draft regula-
tor should open and close freely. 

All electrical connections should be 
checked to ensure tight connections. 
Safety controls such as the high limit 
controls should be tested for functional-
ity. The fan control functions should be 
checked to ensure that all fan speeds 
are operating properly.

 

Open all supply and return air registers 
and grilles. 

Open all valves in oil pipes. 

Turn on electric power supply. 

Set the thermostat above room tempera-
ture to call for heat. The burner will start. 
NOTE: If the furnace has been off for an 
extended period of time, it may be nec-
essary to press the RESET button on the 
primary combustion control relay, (once 
only). If pressing the reset button does 
not start the furnace, refer to Appendix 
C, Troubleshooting. 

 

After the furnace warms sufficiently, the 
circulation fan will start. 

The furnace will continue to run until the 
thermostat call for heat is satisfied. 

Set the thermostat below room tempera-
ture. The oil burner will stop. 

The air circulation blower will continue to 
run until the furnace has cooled suffi-
ciently. 

Set the thermostat to the lowest possible 
setting. Set the manual switch (if in-
stalled) in the Electrical Power Supply 
Line to "OFF". 

: If the furnace is to be shut down 

for an extended period of time, close the 
oil supply valve to the oil burner.
