General hints:
Isolate the appliance from mains supply before opening the appliance
When working with chemicals, i.e. aggressive cleaning materials
always wear protective clothing, goggles and gloves!
After maintenance / repair the appliance must be checked for electric
safety in accordance with your national, state and local requirements!
Whenever working on any gas component like:
Gas valve, gas blower and / or changing connected type of gas a detailed
ue gas analysis MUST be done using adequate CO and CO2
measuring equipment! This shall ONLY be done by trained technicians!
Always check appliance for possible gas leakages!
