19. 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 contractor, the most
important routine service 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 furnace is
factory equipped with a semi-permanent type
filter. If the filter is damaged, replace with filters
of the same size and type. (See Appendix A,
Table A-3).
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 contractor.
Annual Service By Contractor
THE COMBUSTION CHAMBER (FIREPOT)
IS FRAGILE. USE CARE WHEN
INSPECTING AND CLEANING THIS AREA.
The heat exchanger, and flue pipe on
rear
breach units, should be inspected periodically
and cleaned if necessary.
If cleaning is
necessary,
SHUT OFF POWER TO THE
FURNACE
and remove the burner. Using a stiff
brush with a wire handle, brush off scale and
soot from inside the drum and flue pipe.
The
Flue Connector shall be removed to inspect and
clean the flue pipe area. To clean the radiator,
remove the round covers on the two pipes
located on the front panel between the front
panel and the flue pipe. Remove the covers
carefully to avoid tearing the gaskets. 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 industrial a vacuum cleaner.
Before replacing the clean-out covers, inspect
the gaskets. If the gaskets are broken, remove
the remnants and replace with new gaskets.
Replace the cleanout covers and screws.
The blower motor is factory sealed and requires
no routine lubrication.
Inspect the blower fan. Clean if necessary.
Oil Burner Maintenance: Inspect and clean the
oil burner. Be sure to remove any
dust
accumulation in the air band, air shutter, and
blower wheel. The oil burner nozzle and oil filter
should be replaced on an annual basis. The
burner motor is factory sealed and requires no
routine lubrication.
The venting system should be cleaned
and
inspected for signs of deterioration. Replace
pitted or perforated vent pipe and fittings. The
barometric damper 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
functionality. The fan control should be checked
to ensure that the "fan off" function continues to
stop the blower fan at a suitable temperature,
usually between 90°F to 100°F.
