Diagram 13.2
13.1 General Inspection
Before servicing the appliance inspect the following and then
carry out the functional checks:
1. Condition of case and ue.
2. Flue terminal for obstructions.
3. Electrical supply connections.
4. Water connections.
5. Gas connection.
6. System pressure.
Correct any fault before continuing.
13.2 Functional Checks
With the appliance operational carry out the following:
COMBUSTION CHECK - with a ue gas analyser as
described in section 13.9.
GAS RATE CHECK - the gas rates, refer to section
12.4.
If the gas rate requires adjustment you
MUST NOT
adjust the gas valve without a gas analyser, refer to
section 13.9.
If you cannot measure the gas rate it is acceptable to
measure the combustion rate as described in section 13.9,
however, if you do not have either facility then the appliance
MUST be turned off and disconnected until such equipment is
available.
If the Combustion and Gas rate checks did not require
adjustment then it will not be necessary to service the
Combustion Chamber, Burner, Heat Exchanger or Spark
Electrode, proceed to section 13.11.
If the combustion or gas rate requires adjustment you must
complete the servicing as described in sections 13.3 to
13.8, then repeat the functional checks before proceeding to
section 13.11 to complete the servicing.
13.3 Servicing the Appliance
On completion of paragraphs 13.1 and 13.2, proceed with the
following.All routine servicing requirements can be achieved
by the removal of the front panel, see diagram 13.1.

IMPORTANT NOTES:
1. To ensure the continued efcient and safe operation of the boiler it is recommended that it is checked and
serviced at regular intervals. The frequency of servicing will depend upon the particular installation and usage,
but in general once a year should be enough.
2. It is the Law that any servicing is carried out by a competent person.
3. Before commencing with a service or replacement of parts the boiler should be isolated from the electrical
supply and the gas supply should be turned off at the gas service isolation valve.
4. When replacing a part on this appliance, use only spare parts that you can be assured conform to the safety
and performance specication that we require. Do not use reconditioned or copy parts that have not been
clearly authorised by Glow-worm.
5. If any electrical connections have been disconnected and after their connection, checks to the earth continuity,
polarity, short circuit and resistance to earth must be repeated using a suitable multimeter, as described in
section 14.
6. On completion the “Benchmark” Service Record should be completed.
