Step 5: Remove the front panel.
Step 6: Clean the inside of the heater.
Before starting to clean the heater, ensure
that the interior is cool enough to touch.
Wipe all dust off the outside of the housing
with a clean, non-fluffy, damp cloth or
another suitable cleaning aid. Do not forget
to clean the outside of the heat chamber
and the heat exchanger.
Step 7: Re-attach the front panel.
Step 8: Insert the heater plug into the socket.
Step 9: Switch the heater ON.
Step10: Re-programme the heater
(clock and set-back timer).
Attention: If the heater overheats after the completion
of a recovery procedure, contact your dealer and do
not switch the heater on until the problem has been
resolved.
13. Cleaning the filter (monthly)
The filter of the fuel pump must be cleaned each
month and at the end of the heating season.
a) Open the flap on the right of the heater.
b) Close the cut-off valve on the fuel pipe.
c) Place the fuel collecting gutter under the float
house in order to prevent fuel spills. Collect the fuel
in a container.
d) Unscrew the plate covering the filter.
e) Remove the filter and clean it carefully with
compressed air.
f) Replace the filter and screw the covering plate back
into position.
g) Wipe away the spilled fuel.
h) Open the cut-off valve in the fuel pipe. Ensure that
there are no fuel leaks.
Note: At the end of the heating season, remove any
fuel remaining in the float house by unscrewing the
drain plug.
14. Before consulting an expert
The following situations do not indicate defects.
While switching the heater on or off
White smoke can be seen when the heater is switched
on for the first time.
Machine oil or dust on the burner chamber or heat
exchanger is burning.
The flames flicker for several minutes after the heater
has been ignited.
The ignition rod continues to function when the heater
is cold, even several minutes after ignition. This may
cause the flames to be a little larger.
The heater makes intermittent creaking sounds when
warming up or cooling down.
Expansion and shrinkage of metal parts may cause a
slight creaking sound.
Circulation of air in the room does not start immediate-
ly when the heater is lit.
To prevent unpleasant cold draughts, the ventilator
only switches on when the heater has become warm.
A loud clicking sound can be heard during the first use
or when the fuel runs out.
There is air in the fuel pump. This should be gone with-
in approximately 1 minute.
If the clicking sound in the fuel pump does not stop
after approximately 1 minute, push the red ‘reset’ but-
ton on the float chamber (do not hold it in). Also check
whether all the fuel valves are open, the fuel filters are
clean and whether there is sufficient fuel.
Note: The fuel pump may make a slight ticking sound
during normal operation. This does not indicate a prob-
lem.
While the heater is in operation
A part of the burner pot and/or heat exchanger
becomes red in colour during operation.
This is normal and does not indicate a problem.
