Annual maintenance
Maintenance is limited to cleaning the external housing and the combustion chamber.
◼

using a damp cloth. Only do this when the appliance is completely cool
◼
Clean the chimney annually, especially if coal or oil heaters have been used
◼
Have a professional perform annual maintenance to ensure the proper functioning
of the appliance.
Always close the gas shutoff valve during maintenance work.

Checking that the main injector or pilot injector are not clogged
◼
Checking the piezo-ignition and the spark plug

◼
Checking the operation of the appliance:
▪
The ignition of the pilot flame
▪

◼
Removing the build-up on the inside of the window with a damp cloth or a non-
abrasive cleaning agent.
Each gas contains additives in order to detect gas in the event of leakage. These
additives leave a white deposit in the appliance upon burning and thus the glass
should be regularly cleaned. The speed of contamination by this additive depends
on the humidity and the stack effect
◼
Replace a broken or cracked window.
Use only original Well Straler parts.
Always check the gastightness after repairs or maintenance.
