Burner installation location
Burner installation
The burner flange
3
features three
elongated slots and can be used for a
drilling Ø of 150 to 170 mm (VB2.38/54
VD) and/or of 150 to 184mm (VB2.66/95
VD). These dimensions comply with
EN 226.
Sliding pipe bracket
2
on the burner pipe
makes it possible to adjust the installed
depth of the combustion components to
the respective geometry of the combustion
chamber. 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:
• Unscrew screw
5
.
• Turn the burner out of the bayonet
socket and pull it out of the flange.
Fitting the flame tube
• After installing the burner, open the
boiler door.
• Fit the flame tube
6
on the burner pipe
7
and turn clockwise until the bayonet
joint
8
is securely in place.
Installed depth of the burner
The installed depth of the burner must
be set so that the rear edge
9
of the
recirculation orifice
10
is set at the same
level as the boiler door insulation
11
.
Carefully close the boiler door.
Ensure
that the pivoting clearance radius of
flame tube 6 is respected.
If necessary, move the burner back
slightly and then cut the insulation as
needed.
The recirculation orifice must be
positioned in the furnace so that it is
completely unobstructed and easy to
access, to allow flue gases to return
unhindered. This orifice must never
be obstructed by insulating material.
Exhaust system
To prevent unpleasant noise emissions,
right-angled connectors should not be
used on the flue gas side of the boiler.
The minimum distance between the
front edge of the flame tube and the
bottom of the furnace can be calculated
using the following formula:
70 x Q (Q=quantity of fuel oil in kg/h).
For a minimum length of the furnace of
L
F
, the result is:
L
F
= e + L
t
+ 70 x Q
L
t
(VB 2.38...45) = 164
L
t
(VB 2.54...95) = 204
