Fitting the burner head
· Prepare the burner plate/boiler doors
as per the drawing.
· Stipulate interior diameter a 250 mm.
· Four M12 holes (300-400 mm
diameter circle) are required, as
indicated in the accompanying
diagram.
· Screw M12 stay bolts into the
burner plate/boiler door and add the
insulation. If the bolt circle is <400
mm, cut slots to the required size.

Burner tube insertion 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 blast tube, and should have
a maximum 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.
Fitting the burner housing
If the burner housing hangs below the
burner head axis, proceed as follows:
· Fix the burner housing to the burner
head using fixed (opposite the gas
connection) axis F.
· Connect the two ignition cables.
· Close the burner with axis E.
· Tighten safety screw D.
The housing can be mounted above
the axis of the burner head if required.
No other positions for the burner
housing are possible.
· Connecting the oil hose to the oil filter.
· Connect the oil pressure conduit
from the pump to the oil magnetic
valve block.
· Check the oil hose connections for leaks.
· Create an electrical plug-and-socket
connection between the hydraulics
block and the burner.

· Fix the burner head with 4
hexagonal nuts M12.
· The space between the blast tube
and the door insulation must be clad
in fire-resistant material.
N.B.:
Take care not to obstruct the
furnace pressure release pipe, pF.
