• If the fire shuts down for any reason, wait a few
minutes and try re-starting it. If the problem
continues, immediately call an expert engineer to
examine the installation.
• No part of the pilot or its air supply shall be modified
in any way, or put out of operation, even by an
installer/engineer. This can be very dangerous.
• Never use any other parts other than those officially
supplied by Jøtul or its representatives to repair the
oxygen depletion sensor pilot.
• As part of the flame supervision system, the fire will
also shut down if the gas supply fails or the flames
are extinguished for any reason. The valve will fail-
safe and the appliance can be re-lit when conditions
are restored.

9. Commissioning

• Close doors and windows and light fire on high. If
there are extractor fans in neighbouring rooms,
switch them on high and open interconnecting doors.
Burn fire for 5 minutes and then test for spillage from
draught diverter. Use a long smoke match tube from
front of firebox top slot or push burning match right
in until next to draught diverter. All smoke should be
drawn into flue. Any escaping smoke indicates
spillage.
• If spillage is indicated burn for another 10 minutes
and re-test.
• If spillage is persistent, investigate flue pipe system
or extractor fans etc and rectify problem. Minimum
specification of flue must be 3m of 150mm (6")
diameter liner or rigid pipe from the flue connector.
• A smell may be emitted from the fire when first used
due to paint and materials curing. Burn the appliance
on high and open doors and windows to burn this off
as effectively and quickly as possible.
• Check gas pressure. This should be as per specified
gas pressure on data plate. A test point is provided on
the front of the gas control to check this. Check test
point for leakage after testing.

10. Servicing

• This appliance should be serviced at least every 12
months to ensure safe operation.
• Any debris or soot which accumulates on the burner
should be removed regularly.
• Clean the glass with a glass cleaner (or ceramic hob
cleaner for stubborn marks) regularly. Simply remove
the two screws at the bottom of the glass frame under
the control cover and pull outwards and downwards
gently to release the frame and glass. DO NOT use
the appliance without the glass in place and
undamaged. Failure to do this may create a dangerous
situation.
• Remove fuel effect pieces and clean burner with
vacuum cleaner.
• Disconnect gas supply and remove burner unit.
6
• Clean out air intake on venture tube under burner.
• Clean out air intake on front of pilot unit.
• Check and tighten all gas and thermocouple
connections as required.
• Replace burner and reassemble firebed. Replace glass
panel.
• Check ventilation is clear and unobstructed and meets
with requirements.
• Recheck spillage as described in Commissioning
section.

11. Fault Finding

1. No Spark:
• Pilot damaged or electrode too close or far from
pilot head - adjust.
• Detached ignition lead – reconnect.
• Electrode insulator cracked – replace pilot assy.
• Soot or debris on pilot assembly – clean.
• Faulty ignition lead – replace valve assembly.
2. Spark Visible But Pilot Will Not Light:
• Check there is gas to appliance.
• Check restrictor elbow or isolation valve are open.
• Check pipe work is clean – including inlet
connection.
• Pilot injector blocked – clean.
3. Pilot Flame Shortens Or Goes Out When Main Burner
Lit:
• Insufficient gas supply to appliance – check inlet
pipe work.
• Check for kinked bends or debris in pipes and
connections.
• Check meter pressure setting.
• If no blockages or kinks are found then pipes may
be undersized for the run to the appliance.
• Note: This is not an appliance fault.
4. Pilot Goes Out When Knob Released:
• Check tightness of thermocouple connections.
• Hold in knob for longer or more firmly.
• Debris in pilot pipe or jet – clean out.
• Replace pilot assembly.
5. Uneven or poor Flame Picture.
• Re-lay fuel bed.
• Clean out holes in burner board.
• Re-distribute embers (if fitted).
• Check gas pressure.
6. Blue Flames:
• Allow burner longer to warm up.
• Wrong gas pressure.
