To ensure continued efficient operation of the appliance, it is
recommended that it is checked and serviced as necessary
at  regular  intervals.  The  frequency  of  servicing  will  depend
upon  the  particular  installation  conditions  and  usage  but  in
general once a year should be adequate. It is the law that any
service  work  must  be  carried  out  by  registered  personnel
(C.O.R.G.I.).  Before  commencing  any  service  operation,  ISO-

LATE the mains electrical supply, and TURN OFF the gas sup-
ply at the main service cock. Service the appliance by follow-
ing the full procedure detailed below.

5.1

MAIN BURNER ASSEMBLY

– Remove the front casing panel by unscrewing the retaining

screws  and  brackets  situated  above  the  front  panel,  and
pulling the panel forwards from the top corners.

– Remove the 6 fixing screws securing the sealed chamber

front panel then remove the panel.

– Unscrew the 4 screws securing the combustion chamber

front panel and remove the panel, taking care not to dam-
age the insulation.

– Unplug the HT lead from the ignition electrode, then remove

the detection electrode from the burner (one screw).

– Unscrew the burner manifold union and locking nut.

Lift the front of the burner to disengage manifold thread
and then lift the burner clear.

– Remove  the  burner  manifold  by  disconnecting  the  four

screws.

– Inspect  and  if  necessary,  clean  the  injectors,  electrodes,

and the main burner bars

5.2

FAN ASSEMBLY

– Disconnect the electrical connections to the fan. Note the

position of the earth conductor.

16

the installer should:
– Give  the  “Users  Instructions”  to  the  householder  and

emphasise  their  responsibilities  under  the  “Gas  Safety
(Installation and Use) Regulations 1996 (as amended)”.

– Explain and demonstrate the lighting and shutdown proce-

dures.

– Advise the householder on the efficient use of the system,

including the use and adjustment of all system controls for
both D.H.W. and C.H.

– Advise  the  user  of  the  precautions  necessary  to  prevent

damage to the system, and to the building, in the event of
the system remaining inoperative during frost conditions.

– Explain the function of the boiler overheat thermostat, and

how to reset it. Emphasise that if cut-out persists, the
boiler should be turned off and the installer or service
engineer consulted.

– Stress  the  importance  of  an  annual  service  by  a  regis-

tered heating engineer.
