Clean the Burner:
4Loosen the 2 hex head screws and remove
the air intake cover (A) and clear any debris
from the air intake and air damper.
4Disassemble the burner to allow access to
the fan impeller.
4Check the condition of the gaskets between
these parts and replace if necessary.
4Note the position of the air damper adjustment
and check the air damper moves freely.
4Clean both sides of the fan impeller and
remove any debris from the burner housing.
4Check that the impeller rotates freely.
4Reassemble the components.
4Remove the combustion head (B) and
thoroughly clean any deposits.
IMPORTANT: Before removing or fitting a
nozzle (C), loosen screw (D) and move
the electrodes (E) forward.
After refitting check that the electrode
gaps are correct, as shown opposite.
4Remove the nozzle (C).
4Check the nozzle holder is clear of any debris
and clean if necessary.
4Fit a new oil atomising nozzle (C).
DO NOT dismantle the nozzle and DO NOT
clean the nozzle tip.
4Check the electrodes (E) and reset if
necessary as shown opposite.
NOTE: The 12/18 model has a brass air
deflection washer and locating circlip behind
the nozzle. These must be in place for the
correct operation of the burner.
4 Refit the combustion head (B). Check that
the nozzle (C) is central in the combustion
head (B) and the head settings are as
shown. Ensure that the photocell is lined up
with the sight hole.
4 Withdraw the photocell (G) from its housing
and wipe clean.
4 Remove the oil pump internal filter, clean in
kerosene and reassemble.
The internal filter is accessed by removing
screws (H) and the oil pump cover ( J ).
4Replace the standard flexible oil line/s at
every annual service to prevent the
possibility of leakage due to ageing.
4Reassemble the burner components.
4Check the O-ring seal located around the
combustion head and replace if necessary.
This seal must be in good condition, seal
failure will cause flue gases to escape into
the room.
