GENERAL NOTES

To get the best from your boiler please read
these instructions carefully.
SEALED HEATING SYSTEMS
This boiler is fitted to a sealed heating system
which is pre-pressurised. Your installer will
advise you of the minimum and maximum
pressure which should be indicated on the
pressure gauge (see page 7).
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-
pressurised and the cause of the fall
investigated.
CENTRAL HEATING SYSTEMS
During the first few hours of operation of the
central heating system, check that all radiators
are being heated evenly. 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 boiler.
Should water leaks be found in the system or
if excessive venting is required, 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 invalidate the
guarantee.
CONDENSATE DRAIN
This is a condensing boiler and the terminal
will, at times give out a plume of water vapour.
This is quite normal.
The boiler also produces quantities of
condensate which is discharged regularly by
a trap within the boiler via a pump and pipe
to drain. This pipe must not be blocked or
altered in any way.

ROOM THERMOSTAT
A room temperature controller and
programmer should be fitted to control the
central heating. Refer to the instructions
supplied with the thermostat for information
on siting and setting.
THERMOSTATIC RADIATOR VALVES
TRVs should fitted to all but one of the
radiators (or at least those in the sleeping
accommodation). The radiator without the
TRV must be in the same room as the room
thermostat, and must be uncontrolled and
unrestricted. The thermostatic radiator valves
should conform to the requirements of
BS2767:10.
