20.0 mounting
the burner
The supplied burner must be securely mounted to the front of the boiler via the mounting plate provided
and following the instructions supplied with the burner. The maximum length of the burner blast tube must not
exceed 220mm.
If it is necessary to pare away the ceramic fibre insulation of the burner door to allow burner blast tube
entry, then this should be done carefully using a hacksaw blade or similar and ensuring that the blast tube is a
snug fit through the hole in the door insulation. If the hole is oversized then the gap around the blast tube
should be packed with ceramic fibre wool from the combustion chamber side of the door.
If required, a cooling air line may be connected between the burner air test point and the connection on
the combustion chamber viewing window carrier using silicon rubber or similar tubing. This will provide a
cooling to the sight glass and assist in keeping it clean.
