24 221966B
Instruct and demonstrate the safe and efficient operation of the
boiler, heating system and domestic hot water system.
Advise the user, that to ensure the continued efficient 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.
Draw attention, if applicable, to the current issue of the Gas
Safety (Installation and Use) Regulations, Section 35, which
imposes a duty of care on all persons who let out any property
containing a gas appliance in the UK.
REMEMBER: When replacing a part on this appliance, use only
spare parts that you can be assured conform to the safety and
performance specification that we require. Do not use
reconditioned or copy parts that have not been clearly authorised
by Glow-worm
NOTES:. To ensure the continued efficient and safe operation
of the boiler 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 enough.
It is the Law that any servicing is carried out by a competent
person.
Before servicing turn off the gas and isolate the electrical supply
to the boiler.
After completing a service always test for gas soundness and
carry out functional check on controls.
Unless stated otherwise all parts are replaced in the reverse
order to removal.
10.1 Access
Refer to diagram 8.6 and slide controls cover forward and off.
Remove the outer case, see diagram 8.5.
NOTE: As an aid to servicing the air pressure switch tube
connections can be used to obtain a products of combustion
reading.
Remove the RED tube from the connection on the air pressure
switch and insert the analyser probe into the tube.
Switch on the electrical supply to operate the fan and turn on the
gas supply.
On completion of the test switch off the electrical supply and the
gas supply and reconnect the red tube to the air pressure
switch.

10 Servicing
Testing Flue Gases: If any doubt exists that the flue products
are not exhausting correctly, investigate by use of a gas
analyser (FGA).
8.11 Protection against Freezing
If the boiler is to be out of use for a period of time during severe
weather conditions we recommended that the whole of the
system, including the boiler, be drained off to avoid the risk of
freezing up.
It is the Law that servicing is carried out by a competent
person.
Advise the user of the precautions necessary to prevent damage
to the system and the building in the event of the heating system
being out of use during frost and freezing conditions.
Reminder, leave these instructions and the ‘Benchmark’ logbook
with the user.
For IE, it is necessary to complete a "Declaration of Conformity"
to indicate compliance to I.S.813. An example of this is given in
