Burner installation position
Burner assembly
The burner flange
3
is equipped with
elongated holes and can be used with a
hole circle diameter of 150 - 170 mm.
These dimensions comply with EN 226.
Sliding the pipe bracket
2
on the burner
pipe makes it possible to adjust the
installed depth of the combustion head
to the geometry of the furnace
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
3
to the
boiler using screws
4
• Fit pipe bracket
2
to the burner pipe
and secure using screw
1
. Tighten
screw
1
to a maximum torque of 6 Nm.
• 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.
Flame tube installation
• Following installation of the burner,
open the boiler door.
• Fit flame tube
6
onto burner pipe
7
and
turn it clockwise until bayonet socket
8
is firmly engaged.
Burner installed depth
Adjust the burner installed depth in such
a way that the rear edge
9
of the
recirculation opening
10
closes flush
with the boiler door insulation
11
.
Close the boiler door carefully.
Make
sure that there is a free swivel radius
for flame tube 6.
If necessary, pull the
burner back further and cut out the boiler
door insulation accordingly.

Exhaust system
To avoid unfavourable noise emissions,
right-angled connectors should not be
used on the flue gas side of the boiler.
The recirculation opening must be
completely free and easily accessible
in the combustion chamber to allow
exhaust gas to return unimpeded. It
must not be covered by insulation.
The necessary minimum distance
between the front edge of the blast tube
and the rear wall of the combustion
chamber can be calculated using the
formula 70 x Q (Q=kg oil/h). The
minimum length of the combustion
chamber L
F
is therefore calculated as:
L
F
= e + L
t
+ 70 x Q

(1.20) = 156 mm

(1.24) = 156 mm
