MOUNTING OF THE BURNER
Fit the burner to the boiler by means of 4 bolts M12. For fl ange and bolt
dimensions see technical data.
If for some reason you want to separate the burner from the gas fl ange
with burner head and valve package you can do so.
Do like this: - Remove the cover of the fan housing.
- 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
assembly.
- Pull out the burner on the pull rods and put it in a suitable place.
When the burner head and the gas fl ange have been fi 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 housing.
- 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 fl ange.
- Withdraw the gas assembly.
Ensure that the O-ring between the gas assembly and the gas fl ange will
be in the correct position when the gas assembly is fi tted 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.
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).
