9.3 Disassembling and installing

burner

Danger of electric shock!

Before performing service work, power to the boiler must

be shut off and it must be secured from accidentally being switched back on!

Disassembling burner

1. Close gas shut off device

2. Remove front panel of the Power HT gas condensing boiler

3. Release ignition cable, ionisation line and earthing cable.

4. Disconnect connection lines from fan and gas valve

Fig. 31: Loosen screws on the exhaust silencer

C0004594

5. Remove screws on the flange of the venturi tube (2) and loosen the venturi tu-

be with seal (in the flange) from the exhaust silencer (1).

Fig. 32: Release gas connection hose on the gas valve
