Fitting the burner head
· Prepare the burner's casing/boiler
door as per the drawing.
· Establish the internal diameter a at
Ø 172/195 mm.
· To secure the burner head flange, 4
M10 drillings (drilling diameter 220 -
260mm) are required as per the
drawing.

Assembly of burner body
· On burner body, unscrew the two
screws to the maximum.
· Offer up burner body tilted ahead
and hang the two screws in the two
holes of the support.
· Push burner body against the
support and tighten the 2 screws.
· Where required, the housing can be
fitted over the burner head axis.
Other burner housing positions are not
possible.
Burner installation depth and
brickwork
On heaters without a cooled front wall,
unless the boiler manufacturer indicates
otherwise, brickwork 5 as shown in the
illustration is required. The brickwork
must not protrude beyond the leading
edge of the flame tube, and should
have a minimum conical angle of 60°.
The space between the brickwork and
burner should be filled with an elastic,
non-inflammable insulation material 6.
On boilers with reverse firing, minimum
insertion depth A of the burner tube
should be observed as per the instruc-
tions of the boiler manufacturer.
Installation of valve assembly
SKP70/MBVEF
· Check the correct position of the
O-ring B in the gas connecting
flange C.
· Attach the gas valve assembly with
M10 nuts, to ensure that the SKP
controller or the magnetic coils from
MBVEF are imperatively placed
perpendicular to the gas valve
assembly.
· Assembly the pressure pipes
supplied and marked pF, pL and pG
for gas connections to the left or
right.
03/2005 - Art. Nr. 13 018 104A
· Screw the M10 stay bolts into the
burner's casing/boiler door and apply
the insulation material. With a slot
diameter < 260 mm, elongated slots
should be cut to the required
dimensions.
· Secure the burner head using 4
M10 hexagon nuts.
· Fill in the space between the
furnace gate and the burner blast
tube with fire-resistant material.
Caution:
the entry piping to the pF furnace
pressure must not be clogged.
· For SKP70, assemble the back-up
solenoid valve provided (kit) with the
coil towards the top, the gas filter
(kit) horizontally, and with the lid up
(2 connectors).
· Pay attention to the direction of flow.
· Assemble a thermally-triggered valve
and a ball valve (installation side)
upstream from the gas valve
assembly.
