CAUTION!
Avoid operation with damaged seals
Never operate the boiler with damaged seals.
Otherwise, leak air is sucked in, disturbing the
combustion process and causing increased wear.
Always replace seals as soon as they are
damaged.
Close heat exchanger cover
Position the heat exchanger cover carefully.
