4 Ventilation - Always ensure that the boiler has
adequate ventilation. Any ventilation openings
provided by the Installer must not be obstructed.
Periodically check that they are clear.
Do not attempt to 'box in' the boiler or build a
compartment around it before consulting your
Installer.
Do not place any combustible material around or on
the boiler or flue pipe.
5 Flue terminal - The flue terminal on the outside wall
must not be obstructed or damaged.
In severe conditions check that the terminal does not
become blocked by snow.
6 Frost protection - Your Installer may have fitted a
frost thermostat. If not, and you are likely to be away
for a short time, leave the boiler on with the boiler
thermostat set at a low setting. For longer periods the
boiler and system should be drained. Contact your
Service engineer for draining and filling the system.
7 Cleaning and servicing - Lightly wipe over the case
with a damp cloth and a little detergent. Do not use
abrasive pads or cleaners.
You should have your boiler serviced at least once a
year to ensure safe and efficient operation. Contact
your Service engineer for further details.
8 Failure of electricity supply - If the electricity
supply fails, the boiler will not operate. It should
relight automatically when the supply is restored.
If a programmer is fitted (Multi Pass Kitchen models
only) it will retain the time settings for up to 24 hours
and will not have to be reset to the correct time of day
when the supply is restored (the display remains for
up to 1 hour, but will re-appear when the supply is
restored).
Electricity supply
1.8
The boiler requires a 230/240 V ~ 50 Hz supply. It must
be protected by a 5 Amp fuse.
Warning: This appliance must be earthed.

Sealed central heating system
1.9
If your boiler is operating on a sealed heating system, the
installer will have pressurised the system and should have
told you (or set it on the pressure gauge) the system
pressure when cold (this is normally between 0.8 and 1.0
bar, which will increase slightly when hot). If the pressure
(when cold) is below the set pressure mentioned above,
you should contact your Installer or Service engineer to
re-pressurise the system. If the system requires frequent
re-pressuring, ask your Installer or Service engineer to
check the heating system for leaks.
The boiler or system will be fitted with an automatic air
vent to remove air from the system. Any air trapped in the
radiators should be removed by venting the radiators
using the vent screw at the top of each radiator. Only vent
a radiator if the top is cool and the bottom is hot.
Excessive venting will reduce the system pressure, so
only vent when necessary and check the system pressure
as mentioned above. Re-pressurise the system if
necessary.
Note: Your system may incorporate a 'Top-Up' vessel,
advice on how to use it should be obtained from your
installer.
The boiler or system will be fitted with a safety valve to
release excess pressure from the system. If water or steam
is emitted from the end of the safety valve discharge pipe,
switch off the boiler and contact your Installer or Service
engineer.
The expansion vessel air charge must be checked
annually. Failure to maintain an adequate air charge
in the vessel may invalidate the warranty.
