4.7 Mounting on the boiler
Mount the burner to the boiler using 4 bolts. See technical data for the hole
pattern.
To make the fitting process easier, it is possible to separate the burner body
from the gas flange with the combustion head and valve assembly in place.
Proceed as follows:
1. Ensure that no power is going to the burner. Break the main current
and disconnect the Euro plugs from the burner. NB: If the burner is
directly connected, ensure that all components on the burner are
without power.
2. Remove the cover plate from the fan housing.
3. Loosen screw D on the nozzle assembly.
4. Disconnect the electrical cables to the valve assembly and gas damper
motor.
5. Undo the screws (B) on both sides.
6. Undo the end stops (C) on the guides.
7. Disconnect the ignition cable, ionisation cable, and control arm from
the gas nozzle.
8. Pull out the burner body from the guides and put it in a suitable place.
After separating the burner body and the gas flange, it is easier to mount
the gas flange with the burner head and valve assembly to the boiler (loosen
the valve assembly if required). Once the gas flange is fitted to the boiler, it
is easy to lift the burner body up onto the guides. Assemble the burner in
reverse order to its disassembly.
