Inspection and maintenance
The operator is responsible for the safety and environmental
compatibility of the heating system (see local regulations).
It is therefore recommended that you enter into a maintenance
and inspection contract with an approved contractor that
provides annual inspection and maintenance. This ensures high
efficiency and environmentally compatible combustion.
Cleaning the outer casing
Wipe down with a damp cloth. Do not use any abrasive or
corrosive cleaning agents.
