Safety devices
Burner safety
: If there are faults in the gas supply or in
lighting, the safety device (thermocouple) will shut
down the gas tap automatically.
-
It is advised for safety reasons to wait 5 minutes
before lighting again the appliance.
-
Eliminate any cause of the safety lock.
-
Wait for around 10 min and re-light the appliance in
accordance with section 'Lighting'.
F
In case of repeated burner cut off, due to a flue
blockage, it is required to check the complete
flue system (flue and connecting pipe and air in-
let). We recommend that you engage the servi-
ces of a professional engineer for the regular
maintenance requirements.
3.4
Maintenance
Appliance servicing must be done once a year during
summer time by a qualified engineer to avoid any
problem or fault during winter-time. This person will also
check safety devices.
Clean the painted components and the glass with a
sponge or a chamois leather to avoid dirt becoming
encrusted. Do this when the appliance is cold using a
suitable proprietary cleaner. Never use abrasive
products.
Annual maintenance by a specialist ensures that the
appliance will operate correctly during the heating
seasons.
3.5
Trouble shooting
The gas pilot will not ignite or stay lit ?
Ensure the gas is turned on at the appliance and the
meter/cylinder.
Depress the control knob for at least twenty seconds
once the pilot is alight to ensure the operation of the
safety thermocouple valve.
Ensure that the pilot injector is not obstructed or
blocked and it is free from any dust or dirt.
Ensure that the thermocouple has not been damaged in
transit. This is a very delicate Electro-magnetic device.
On propane, the cylinder could be empty.
The pilot is not burning or performing correctly?
Ensure the pilot flame is the correct size for the type of
gas. The flame should be focused on the thermocouple
probe.
The pilot flame will have been set correctly in the
factory.
The Main Burner does not seem to be burning
correctly ?
Ensure adequate gas pressure to the appliance. Test
pressure by releasing the pressure test screw and
applying a manometer. Ensure adequate volume of gas
is being used. Once the fire is burning on maximum,
turn off all other gas appliances in the house and
calculate the fuel being burned from the gas meter.
Make sure that the burner is burning correctly. The
flame should be even across the top of the burner
before any coals are placed on top.
Piezo-electric igniter
:
The spark between the
electrode and the head of the pilot light is not
clean ; there is no spark when the lighter is operated.
-
Check the contact of the high tension cable of the
spark plug. When the end of the cable is held at about
3 mm from the end of the spark plug, a spark should be
produced when the piezo-elertric igniter is operated.
-
Check that the insulation of the spark plug is not
cracked, and replaoe the spark plug if necessary.
The thermocouple
:
When the unit is started up, the
pilot light flame goes out when the handle is turned from
the “ignite” position to the “pilot light” position.
•
The thermocouple is not at a high enough
temperature, the pilot light flame is too short.
-
Check that the injector (rep. , fig. 6, p. 14) is not
partially blocked.
To gain access to the injector, the coals and the burner
must first be dismounted (3 screws).
•
Bad contact at the connection of the thermocouple
to the valve.
-
Check the tightness of the screw. It should be
reasonably tight.
•
Carbon deposit on the end of the thermocouple,
which reduces temperature transmission.
Clean the end of the thermocouple with emery paper.
