MOUNTING OF THE BURNER
172 205 20 08-01
Fit the burner to the boiler by means
of 4 bolts M12. For ange and bolt
dimensions see technical data.
If for some reason you want to sepa-
rate the burner from the gas ange
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
ange have been tted 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
ange.
- Withdraw the gas assembly.
Ensure that the O-ring between the
gas assembly and the gas ange will
be in the correct position when the
gas assembly is tted again.

shrouded disc in the blast tube

the position of the shrouded disc in
