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 a
competent person such as British Gas or other CORGI regi-
stered personnel. Before commencing any service operation,
ISOLATE the mains electrical supply, and TURN OFF the gas
supply at the main service cock. Service the appliance by fol-
lowing the full procedure detailed below.

5.1

MAIN BURNER ASSEMBLY

– Remove the front casing panel by unscrewing the retai-

ning screws and brackets situated above the front panel,
and pulling the panel forwards from the top corners whil-
st holding the side panels in place.

– Remove both casing side panels by unscrewing the three

screws in each situated underneath and above the side
panel, and lift the panels vertically upwards to release
them (fig. 8).

– Release the two spring clips and remove the four fixing

screws securing the sealed chamber front panel then
remove the panel (fig. 19).

– Unscrew the 5 screws securing the combustion chamber

front panel and remove the panel, taking care not to
damage the insulation.

– Unscrew the spark electrode and withdraw. 
– Unscrew the pilot pipe from the pilot burner and with-

draw the pipe. Carefully remove the pilot injector. It may
be necessary to remove the pilot bracket to do this.

– Unscrew the burner manifold union.
– Remove the burner assembly locking nut.
– Lift the front of the burner sufficiently to disengage the

manifold thread. Carefully slide the burner forwards and
withdraw the burner.

– Remove the burner manifold by disconnecting the four

posi-head screws (10 fig. 24).

– Inspect and if necessary, clean the injectors.
– Inspect and if necessary, clean the main burner bars.

5.2

PILOT ASSEMBLY

– Inspect the pilot injector; clean if necessary.
– Inspect and clean (if necessary) the pilot burner. Ensure

that it is free from debris.

– Re-assemble the burner assembly in reverse order ensu-

ring that the baffle is correctly re-positioned. Do not
reassemble any other components until the service is
completed.

5.3

FAN ASSEMBLY

– Disconnect the electrical connections to the fan. Note

the position of the earth conductor.

– Pull off the two pressure sensing lines.
– Remove the screws securing the fan mounting plate.
