IMPORTANT: 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.
MAINTENANCE AND SERVICE
A:Routine Maintenance By Home Owner
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.
B: Annual Service By Contractor
THE Combustion chamber (firepot) IS FRAGILE. use care when inspecting and cleaning this area.
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.
OPERATING INSTRUCTIONS
Before Lighting
Open all supply and return air registers and grilles.
Open all valves in oil pipes.
Turn on electric power supply.
To Light Unit
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.
To Shut Down Unit
Set the thermostat to the lowest possible setting. Set the manual switch (if in- stalled) in the Electrical Power Supply Line to "OFF".
NOTE: If the furnace is to be shut down for an extended period of time, close the oil supply valve to the oil burner.
DO NOT ATTEMPT TO START THE BURNER WHEN EXCESS OIL HAS ACCUMULATED, WHEN THE FUR- NACE IS FULL OF VAPOUR, OR WHEN THE COMBUSTION CHAMBER IS VERY HOT. NEVER BURN GAR- BAGE OR PAPER IN THE FURNACE, AND NEVER LEAVE PAPER OR RAGS AROUND THE UNIT.
