GENERAL NOTES
To get the best from your appliance plea-
se read these instructions carefully.
SEALED HEATING SYSTEMS
This appliance is fitted to a sealed hea-
ting system which is pre-pressurised.
Your installer will advise you of the mini-
mum and maximum pressure which
should be indicated on the pressure
gauge.
Check regularly that the pressure is
maintained and contact your installer or
maintenance engineer if a permanent
significant drop in pressure is indicated
on the pressure gauge. If the system
loses pressure it should be re-pressuri-
sed and the cause of the fall investiga-
ted.
CENTRAL HEATING SYSTEMS
During the first few hours of operation of
the central heating system, check that all
radiators are being heated at an even
rate. If the top of a radiator is at a lower
temperature than the bottom then it
should be vented by releasing air
through the venting screw at the top of
the radiator. Ask your installer to show
you how this is done.
This boiler is fitted to a sealed system;
repeated venting will reduce the quantity
of water in the system and this must be

replenished for safe and satisfactory
operation of the appliance.
Should water leaks be found in the
system or if excessive venting is requi-
red, then a service engineer must be
contacted to inspect the installation and
rectify any fault.
Only additives that are compatible with
aluminium may be used in the system.
Any incompatible additive used will inva-
lidate the guarantee.
PLUMING AND CONDENSATE DRAIN
This is a condensing appliance and the
terminal will, at times give out a plume of
water vapour. This is quite normal.
The appliance also produces quantities
of condensate which is discharged regu-
larly by a siphon within the boiler via a
pipe to drain. This pipe must not be
blocked or altered in any way.
CLEARANCES
Your installer will have provided adequa-
te space around the appliance for safety
and servicing access. Do not restrict this
space with the addition of cupboards,
shelves etc. next to the appliance.

ROOM THERMOSTAT
A room temperature controller and pro-
grammer should be fitted to control the
central heating. Refer to the instructions
supplied with the thermostat for informa-
tion on siting and setting.
THERMOSTATIC RADIATOR VALVES
It is recommended that this type of valve
is fitted to all but one of the radiators (or
at least those in the sleeping accommo-
dation). The remaining radiator, which
must be where the room thermostat is
located, should be uncontrolled and
must be left open. The thermostatic
radiator valves should conform to the
requirements of BS2767:10.
