WARNING: Flue gas leakage
The seal between the burner and the mounting flange
must form a gas tight seal to prevent leakage of
potentially dangerous gas from the combustion
chamber.
▶ Unless the burner is level when pushing the burner
into the flange the O-ring may not seat properly
allowing flue gas to escape!
▶ Always check that the O-ring seal (Fig 88item A) is in
good condition before fitting the burner.
Replace the O-ring seal if defective.
