ENGLISH
When the pilot goes out – but the
gas supply is ok:
This is the trouble-shooting procedure for the
thermocouple, (fig. 4)
• Check the copper wire of the thermocouple for cracks
or damage.
• Check the gasket at the valve by loosening the nut that
holds the copper wire. Look for signs of damage, if the
nut has been tightened too hard. A damaged gasket
involves a lot of resistance at contact with metal and
consequently the voltage to the valve will be too small.
• Make sure the flame is centred at the thermocouple.
• Make sure the thermocouple is enveloped by the flame
up to at least 3 mm from the tip (fig. 4).
• Check the voltage generated by the thermocouple.
Connect the multimeter (fig.7-E) with plus to the ball
point (fig. 7-D) at the end of the copper wire. Connect
minus to the copper wire.
• Light the pilot (fig. 7-A) and hold in the control knob to
prevent the flame on the pilot burner from going out.
• At this point the multimeter should show 14-28 mV.
If it is the beginning of a new heating season and the
fireplace has not been used, a coating may appear on the
tip of the thermocouple. This coating can be removed with
fine grinding paper. Use a 9mm cap wrench when replacing
the thermocouple. The nut on the thermocouple must not
be tightened too much, just a half turn.
If the pilot and main burner shuts off in operation for no
apparent reason (especially during windy or stormy
conditions) and will not relight, it is possible that the flue
system safety switch has operated. Allow the appliance to
cool down and relight.
Any obstruction to the flow of exhaust gases up the flue
can cause this switch to operate thereby making the
situation safe. If the appliance cuts out repeatedly, do not
continue to use the appliance and seek flue checking and
service from qualified personnel before re-using the
appliance.

Problems with the flame pattern

The product is set up during manufacture. Should problems
with the flame pattern occur, the log set/coal set must be
disassembled and checked. Check if the right air regulator
is mounted correctly. (See the instructions manual for the
conversion set.)
If the incline of the vent system is too small, or airflow
through the flue system is slow the flames could stretch
towards the glass.
The reason for this may be too little air for combustion at
the front of the coals. To correct this, 2 areas on the rear of
the front coal support bracket can be opened by pressing
inwards (see fig. 8).

That will give more air to the combustion zone at the front.
The adjustment may vary from one installation to another
and several attempts may be required.
Too large an opening may result in too small flames.

Maintenance

The complete installation, which includes the gas supply,
the actual appliance and the vent system, must be
inspected annually. The inspection must be carried out by
qualified service personnel.

External maintenance

Painted products may change color after some years of
usage. The surface should be cleaned and brushed free of
any loose particles before new stove paint is applied.
Enamelled products must only be cleaned with a dry cloth.
Do not use water or soap. Stains can be removed with an
appropriate cleaning agent (oven cleaner etc.).
