INSTALLATION MANUAL
!Tip
When checking whether the main burner continuous to burn, it is possible that it switches off after 15 seconds. In
that case, this will be caused by the fact that there is no ionization detection and because the glass window has
not been placed. This can be regarded as a situation where the main burner continues to burn.
!Caution
Always wait 5 minutes before re-igniting the appliance.
No changes may be made to the gas control.
7.3.2 Main burner
!Caution
The ignition electrode should ignite the main burner within a couple of seconds and without popping.
The main burner(s) must cross the full burner smoothly and without popping and continue to burn.
If the appliance does not ignite after three restarts and enters hard lockout, it may never be reset by
disconnecting it from the power supply. If a restart is necessary after all: remove the glass pane and make sure
the gas is able to escape from the appliance. After this, the appliance may be disconnected from the power
supply for 10 seconds. After these 10 sec., the power supply may be reconnected. Ignite the appliance in the
same way as the first ignition, as indicated in section 7.3.1.
Ø
Check operation of the main burner from a cold condition.
Ø
If sparks are determined between the ignition electrodes, the main burner should burn within a few seconds.
!Tip
The flame picture and a good flame transfer can only be properly judged if the glass window is installed.
Use the malfunction search diagram (Appendix 1) if the ignition of the main burner does not comply with the
above-mentioned requirements.
7.4 Flame picture
The flame picture can only really be assessed when the appliance has been burning for several hours. Volatile
components from paint, materials, etc., which evaporate in the first hours, will affect the flame picture.
Ø
Check whether the flame picture is acceptable.
Ø
Consult the malfunction search diagram (Appendix 1) if the flame picture is not acceptable, in order to solve the
problem.
8. Maintenance
Once per year, the appliance must be checked, cleaned and, if necessary, repaired by a competent installer in the
field of gas heating and electricity. Check at least whether the appliance is working properly and safely.
!Caution
Close the gas tap when performing maintenance work.
Check the gastightness after repair.
Make sure there is no voltage on the appliance.
SS-absolutely do not clean the concentric system (internally) with a steel brush or metal sponge, for example.

Ø
Clean glass pane(s), if necessary.
!Caution
Only clean a glass pane once it has reached room temperature.
Caution!
Avoid damage to the glass pane(s).
Avoid/remove fingerprints on the glass pane(s), as they will burn into the glass.
Clean the pane(s) as described in the user manual.
Regularly remove accumulated dirt, as it can burn into the glass.
Do not use the appliance when a pane is broken and/or cracked, until it has been replaced as described from
section 5.10.
!Caution
If necessary, place back the wood or pebble set correctly; for this, see from section 5.10.
Ø
Inspect the flue gas discharge system.
!Caution
You must always perform a final inspection.
