Mounting Of The Burner; Inspection Of Gas Assembly - Bentone BG550 Series Installation And Maintenance Instruction

4. Mounting of the burner

Fit the burner to the boiler by means of 4 bolts M12. For lange and bolt
dimensions see technical data.
If for some reason you want to separate the burner from the gas lange 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 lange have been itted 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 lange.
• Withdraw the gas assembly.
Ensure that the O-ring between the gas assembly and the gas lange will be
in the correct position when the gas assembly is itted again
!
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).
