3.4.4. Extinguishing the stove fully
From any heat setting or the permanent pilot, depress
control knob fully and turn clockwise to ‘OFF’ position.
3.5. Safety mechanisms
The Belfort in both natural gas and LPG, incorporates a
number of safety mechanisms.
3.5.1. Flame supervision device
Since 1st January 1996, under the new European
standard EN5613, all stoves are required to have a
‘Flame Supervision Device’ (FSD). If the pilot should
become accidentally extinguished, there exists a
potential for a build up of unburned gas. In this situation
the FSD will automatically cut off the gas supply to the
pilot and main burner.
The FSD device works on a thermocouple basis. Next
to the pilot flame on the appliance is a small sensor
containing the thermocouple. This sensor responds to
heat and is linked directly to the gas inlet supply on the
appliance. When lighting the stove, there is a need to
keep the control knob depressed for about 15 - 20
seconds. This allows the thermocouple to reach its
operating temperature. The device will not allow any
gas to enter the burner until the pilot flame has heated
the sensor up to this operating temperature.
If the pilot is extinguished the gas supply will be
automatically cut.
3.5.2. Thermostatic switch (ttb)
The appliance is fitted with a thermostatic switch (TTB)
which senses any excess temperature due to a flue
blockage. In the event of a partial or total blockage the
gas supply will be automatically cut. Should this occur
turn the control knob to the off position and wait
a p p r o x i m a t e l y 1 0 m i n u t e s f o r t h e s w i t c h t o
automatically reset.
Re-light the stove in accordance with section 5
‘Operating the stove’.
On repeated operation of the thermostatic switch the
stove should be turned off and under no circumstances
re-lit until specialist advice has been obtained from your
dealer.
3.5.3. Ignition mechanism
Many gas stoves have electric ignition which requires
mains (240V) supply. This can create problems both
with the presence of water or absence of mains supply.
The Belfort has a Piezo ignition which requires no
external power source. The piezo works on the same
principle as a cigarette lighter, providing a spark when
required.
3.6. Cleaning
Ensure that the stove is turned off before cleaning and
do not attempt to clean if the unit is still hot.
The coals within the appliance are manufactured from
high quality ceramic fibre and should only be arranged
as shown in the coal layout diagram.
After continued use there may be a build up of soot on
the coals which will require removal. Any form of
deposits will reduce the performance of the appliance
and should be removed using a soft brush. Cleaning
should be undertaken with a soft brush or alternatively
with a vacuum cleaner; care should of course be taken
to ensure the aperture of the vacuum is smaller than the
smaller coal size.
Care should also be taken to ensure deposits from the
chimney do not fall into the appliance. If this does occur
then cleaning should be undertaken promptly and the
cause investigated before further use.
The Belfort Stove is supplied with ceramic coals, which
are to be arranged by the fitter in strict accordance with
the installation instructions. There should be no need
for the purchaser to alter the layout of the coals and it is
recommended that such a practice should be avoided if
at all possible.
Should however any coals become broken during the
cleaning process it is essential that replacements are
purchased, as there is an optimum number of coals for
a satisfactory functioning of the stove and the flame
picture.
To clean the appliance open the door by releasing the
door latch (rep. 1, fig. 7, p. 7). The door should be
shut correctly before use of the appliance.
3.7. Servicing
It is essential that the appliance is regularly serviced
and maintained by a qualified person, and the chimney
or flue system checked annually.
If the appliance is heavily used is advisable to
undertake more regular servicing, however under
normal circumstances annual servicing should be
sufficient.
