Do not open the casing or tamper with gas, wiring, combustion components or the flue. If you smell gas, leave the area and call for help from a safe place; in immediate danger, call 112.

Before you buy

The right part start with one detail.

Two pieces can look the same and belong to different versions. We help you check it out.

Keep letters, zeros and suffixes. Search for the complete code and contrast connections and version.
