Burner assembly
The burner is fixed by mean of connecting
flange and therefore to the boiler.
Installation:
• fix the flange 3 to the boiler with
the screws 4
• turn the burner slightly, guide it into
the flange and secure using screw 5
Removal:
• loosen screw 5
• turn the burner out and pull it out of
the flange.
Burner blast tube insertion depth and
brickwork
Unless otherwise specified by the boiler
manufacturer, heat generators without a
cooled front wall require brickwork or
insulation 5 as shown in the illustration.
The brickwork must not protrude beyond
the leading edge of the blast tube, and
should have a minimum conical angle of
60°. Gap 6 must be filled with an elastic,
non-combustible insulation material. For
boilers with reverse firing, the minimum
burner tube insertion depth A as speci fied in
the boiler manufacturer's instructions must
be observed.
Exhaust system
To avoid unfavourable noise emissions,
right-angled connectors should not be
used on the flue gas side of the boiler.
