Boiler Design
Description
The boiler is designed to provide central heating from a
fully pumped open vented or sealed water system with an
indirect cylinder.
Once the controls are set the boiler operates automatically.
Pluming from ue terminal
Like all condensing boilers it will produce a plume of
condensation from the ue terminal in cool weather.
This is due to the high efciency and hence low ue gas
temperature of the boiler. It is normal and not a fault
indication.
Compartment or Cupboard Installations
Ventilation is not required for compartment or cupboard
installations.
Do not use the compartment or cupboard for storage.
Electrical Supply Failure
The boiler will not work without an electrical supply and
normal operation of the boiler should resume when the
electrical supply is restored.
If the boiler does not resume normal operation, check the
external controls, it may be necessary to "reset" the boiler,
refer to the following section, "Boiler Safety Devices".
Diagram 1
14618
* A removable compartment door can be placed a minimum
5mm in front of the boiler. A clearance of 600mm is required
from a fixed surface.
▲ 5mm to a non-permanent surface
20mm to a permanent surface
■ This clearance can be reduced to 20mm for a direct rear flue.

Boiler Safety Devices
Overheat Reset
The boiler software is designed to recognise the potential
for an overheat lockout and will shutdown before this
happens. To restart the boiler, press the reset button, see
diagram 2.
If the boiler fails to resume normal operation and all
external controls are calling for heat, then call your
Installation/Servicing company or British Gas Service.
Frost Protection
With the gas and electric supplies ON and irrespective of
any room thermostat setting, the integral frost protection
device will operate the pump when the temperature of the
boiler water falls below 8OC.
A timer is used so that the temperature can be checked
periodically. After 10 minutes the pump will be stopped
if the temperature is higher than 10OC or has already
reached 35OC.
The burner will only activate if the boiler temperature
does not reach 10OC after 30 minutes or at any time if the
temperature drops to 5OC.
The burner will switch off when the temperature reaches
35OC.
NOTE: Any other exposed areas of the system should be
protected by a separate frost thermostat.
Condensate Drain Blockage
As a safety feature the boiler will stop working if the
condensate drain becomes blocked. 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. The boiler
should then restart. Contact your Installation/Servicing
company or British Gas Service if the fault persists.

www.house.co.uk
Frost Protection
If the mains electricity and gas services are to be turned
off for any long periods during severe weather, it is
recommended that the whole system, including the boiler,
should be drained to avoid the risk of freezing.
Spare Parts
REMEMBER, When replacing a part on this boiler, use only
spare parts that you can be assured conform to the safety
and performance specication that we require. Do not use
reconditioned or copy parts that have not been clearly
authorised by British Gas.
If replacement parts are required contact British Gas using
the telephone number on the inside front cover of this
booklet.
Please quote the name of the boiler, this infomation will be
on the name badge on the front case.
If in doubt seek advice from the local gas company or
British Gas using the telephone number on the inside front
cover of this booklet.
General Note
Servicing/maintenance should be carried out by a
competent person in accordance with the rules in force in
the countries of destination.
If this boiler is installed in a rented property in the UK there
is a duty of care imposed on the owner of the property by
the current issue of the Gas Safety (Installation and Use)
Regulations, Section 35.
Servicing
To ensure the continued efcient 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 site conditions and usage, but in general, once a
year should be enough.
To obtain service, please call your installer or British Gas
Service using the telephone number on the inside front
cover of this booklet.
Cleaning
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 paintwork.
