is equipped with
elongated holes and can be used with a
hole circle diameter of 150 - 184mm.
These dimensions comply with EN 226.
Sliding pipe bracket

on the burner pipe
makes it possible to adjust the installed
depth of the mixing unit to the geometry
of the combustion chamber concerned.
The installed depth remains the same
during fitting and removal.
Pipe bracket
2
secures the burner to the
connecting flange and therefore to the
boiler. This completely seals off the
combustion chamber.
Installation:
• Secure connecting flange

Burner tube installation depth and
brickwork surround
Unless otherwise specified by the boiler
manufacturer, heat generators without a
cooled front wall require brickwork or
insulation
5
as shown in the illustration
opposite. The brickwork must not
protrude beyond the leading edge of the
flame tube, and should have a maximum
conical angle of 60°. Space
6
must be
filled with an elastic, non-flammable
insulation material.
For an installation with the burner
in inverted position, the display
must also be inverted.
To do this, when the burner is
connected to the mains power
supply, press and hold buttons
BP1
and
BP2
together, until the
change is seen.
This operation is only possible
when the burner is off!
Exhaust gas evacuation system
To avoid unpleasant noise emissions,
right-angled connectors should not be
used on the flue gas side of the boiler.
