IMPORTANT:
After completing any servicing or
replacement of gas carrying components it
is essential that a test for gas soundness
is always carried out along with functional
checks in operation.
7.2
TO INSPECT AND CLEAN THE
APPLIANCE
Before carrying out the cleaning
operation, cover the electrical control
panel with a piece of waterproof material
to protect it from debris.
Inspect the heat exchanger for any
blockage. Deposits of any material should
be brushed away using a soft brush.
NOTE:
Do not use brushes with metallic
bristles.
Examine internal pipe-work connections
and automatic air vent for any water leaks
and rectify if necessary.

Any deposits should be flushed out.
Reassemble and refit the condensing

When refitting the cap ensure that a
watertight seal is achieved, but do not use
excessive force.
Examine the spark and sensing electrodes
for any mechanical damage. Clean away
any debris and check the spark and sensing
gap.
Examine flue duct and flue manifold and
ensure that there is no obstruction.
Examine the gasket at the entry into the
flue manifold.
It is essential that a good seal is made at
the outlet to the flue manifold, renew this
gasket if there is any sign of damage or
deterioration.
8 REPLACEMENT OF PARTS
8.1 GENERAL
Replacement of parts must be carried
out by a competent person.
Before replacing any parts the boiler should
be isolated from the mains electric supply
and the gas should be turned off at the
service cock on the boiler.
After replacing any parts always test for
