person in accordance with the rules in force in the countries of
destination.
To obtain service, please call your installer or Heatcall (Glow-
worm’s own service organisation) using the telephone number
on the back cover of this booklet.
Please be advised that the ‘Benchmark’ logbook should be
completed by the installation engineer on completion of

Clearances
If the boiler is fitted into a compartment or cupboard do not use
the compartment or cupboard for storage.
Protection Against Freezing
The boiler has a built in frost protection programme as long as
the electricity and gas are left switched on.
This device only protects the boiler. Any other exposed areas
of the system should be protected.
If the mains electricity and gas are to be turned off for any long
periods during severe weather, it is recommended that the
whole system, including the combination boiler, should be
drained to avoid the risk of freezing.
If in doubt, contact you installation/servicing company for advice.
As a safety feature the boiler will stop working if the condensate
drain becomes blocked. The display will repeatedly flash ‘
0
’
then
‘
8
*
’
. During freezing conditions this may be due to the
forming of ice in the condense drain external to the house.
Release an ice blockage by the use of warm cloths on the pipe.
Press the reset button to restart the boiler. Contact your
installation / servicing company if the fault persists.
Draining and Filling
CAUTION: This boiler works in a pressurised system which
must only be drained, refilled and pressurised by a competent
person.
NOTE: If the pressure gauge indicates a loss of system
pressure, i.e. less than 0.7bar, the appliance will shut down
showing flashing:
‘
1’
then ‘
2
*
’ on the display. YOU MUST
CONTACT YOUR INSTALLER.
Pressure Relief Safety Valve
CAUTION: A pressure relief safety valve and discharge pipe is
fitted to the boiler. This valve must not be touched. Should there
be any discharge from the pipe, isolate the boiler electrical
supply and contact your installation/servicing company.
Cleaning
WARNING: This appliance contains metal parts and care
should be taken when handling and cleaning with particular
regard to edges.
The boiler casing can be cleaned using a mild liquid detergent
with a damp cloth, then a dry cloth to polish.
Do not use any form of abrasive or solvent cleaner as you may
damage the paint work.
Boiler Casing
CAUTION. Do not remove or adjust the casing in any way, as
incorrect fitting may result in incorrect operation or failure to
operate at all. If in doubt seek advice from the local gas
company or your installation/servicing company.
Replacement Parts
If replacement parts are required apply to your local supplier or
British Gas.
Please quote the name of the appliance.
Condensation Pluming
Like all condensing boilers this appliance will produce a plume
of condensation from the flue terminal in cool weather. This is
due to the high effiency and hence low flue gas temperature of
the boiler.
