All routine servicing requirements can be achieved by

the removal of the front casing, inner case and chassis

panel only.

• Remove the two screws on the underside of the front

casing and lift off.

• Remove the two screws on the front of inner case and

lift off, see fig 8.1.

• Drop down the electronics box into the service position.

• Remove the four screws from the chassis panel, see

fig 8.2. Remove the chassis panel by pulling it out at

the top from its retaining slots.

Note!

When replacing chassis front panel ensure the

bottom fits behind lip.

Unless stated otherwise any part removed during servic-

ing should be replaced in the reverse order to removal.

With the appliance operational carry out the following

functional checks:

1. Check the combustion, with a flue gas analyser, see

section 9.

2. Should the combustion measurement or flame and

gas valve be correct, then it is not necessary to re-

move the burner assembly for a service.

3. Check the operational performance of the central

heating agrees with the technical specification.
