MOUNTING OF THE BURNER
172 205 20 08-01
Fit the burner to the boiler by means
of 4 bolts M12. For flange and bolt
dimensions see technical data.
If for some reason you want to sepa-
rate the burner from the gas flange
with burner head and valve package
you can do so.
Do like this:
- Remove the cover of the fan hou-
sing.
- Loosen the nut D of the gas
assembly package.
- Loosen the electric cables to the
valve package.
- Loosen the screws B on both
sides.
- Loosen the stop bolt C on the pull
rods.
- Loosen the ignition cable and the
ionisation cable from the gas ass-
embly.
- Pull out the burner on the pull rods
and put it in a suitable place.
When the burner head and the gas
flange have been fitted to the boiler it
is easy to lift up the burner to where
it belongs.
Inspection of gas assembly
If the gas assembly needs to be
inspected the pull rods are very
useful.
Do like this:
- Remove the cover of the fan hous-
ing.
- Loosen the nut D of the gas
assembly package.
- Loosen ignition cable and ionisation
cable of gas assembly.
- Loosen the screw A on both sides.
- Pull out the burner on the pull rods.
- Loosen the screws B on the gas
flange.
- Withdraw the gas assembly.
Ensure that the O-ring between the
gas assembly and the gas flange will
be in the correct position when the
gas assembly is fitted again.
Adjustment of the position of the
shrouded disc in the blast tube
Sometimes it is necessary to adjust
the position of the shrouded disc in
the blast tube. This can be done with
the screw E (can be adjusted when
the burner is in operation). If you turn
the screw to the left the shrouded
disc will move forward (+), to the right
it will move backward.
SERVICE POSITION
NOTE!
For maintenance of the brake plate,
nozzles, electrodes etc, when using
a long design of the burner tube, you
have to
remove the nozzle assembly
from the connecting pipe and move
the assembly backwards
in the fan
housing (from the boiler).
