Please note: turn off the gas supply and power supply as much as possible during maintenance activities. Maintenance
activities should be performed by a qualified fitter. Close the gas valve while maintenance activities are being performed
Inspect
Work activities OK
1 General inspection a The main burner should ignite smoothly (within several seconds) and not give a bang sound due to
delayed ignition. Go to number 7 if there appears to be delayed ignition.
b Check the flame image. No flames against the glass. The flame image should be stable (See page 22
item 12.7). The flame should be yellow after approximately 15 minutes; go to number 7 if the flame
image is blue.
c Check for excessive formation of soot on the inside of the glass/combustion chamber and on decorative
parts. Go to number 7 if there is excessive formation of soot.
2 Door/front a check for obstructions in the convection air openings
3 Glass window, seal. a check the glass window for cracks etc. Replace if damaged, cracked, or broken.
b check the seal of the glass window; this needs to join the unit and glass window. Replace if required.
c check any hinges, seals, quadrants etc.
d clean the glass. Check there is an even (not too large) load on the glass window. Prevent point load.
4 Gas control compart-
ment and convection
part of the unit
a clean these areas with a vacuum cleaner. Do so carefully. Remove parts that do not belong here.
b check if the convection airflow is free. .
5
Decorative parts (logs/
pebbles etc.)
and
(pilot)burner
a remove decorative parts and clean the burner (be careful with ceramic burners!) with a vacuum cleaner.
b inspect decorative parts for damage/cracks/discolouration and clean with a soft brush if required
c check if the burner cover is intact and free of corrosion. Replace the burner if required.
d after completing the inspection: replace decorative parts, exactly as stipulated by the manufacturer.
Ensure the pilot burner is kept free!
e check if the pilot flame protection is intact (if applicable).
f check the piezo for sufficient spark power, and ensure the ignition cable is free from metal parts/
electrical parts.
6 Combustion chamber a check the condition of the finishing, such as varnish and enamel. Check for corrosion. Repair if
required.
b
replace the unit if there are holes. Close the unit for further use.
c check overpressure hatches or overpressure construction for sealing and sufficient movement/deposits.
7 Ignition and operation
of the main burner
a remove the burner from the unit and check whether the main injector is dirt-free.
b check if the primary ventilation opening in the main burner is dirt-free.
c mount the burner and check if the burner is in a good position in relation to the pilot burner.
d check if the burner is fixed and cannot move.
e check if the pilot burner burns well, with a blue flame (blue only)
f check if the burner ignites uniformly across the entire surface and without significant delay.
g check if the flame image is uniform and stable (manufacturer’s description).
h check the initial and burner pressure. Do not forget to close the pressure measuring points.
i check if gas control parts are intact, and that plastic parts have not melted, for example.
j check electrical wiring for damage and ensure they are away from hot parts of the unit.
8 Installation a check if convection grates are dust-free and dirt-free
b check if there is sufficient distance between the unit and flammable furniture
9 Flue tube/air supply a where possible, inspect the general state of the exhaust/supply system and check for blockages / leaks /
corrosion.
b check the outlet, which should be free from dirt and blockages.
c specifically check for leaking of cement borders etc.
10 Remote control a check for correct functioning of the remote control.
11 Ventilators (if present) a clean the convection ventilators and check for correct functioning.
