GENERAL NOTES

CENTRAL HEATING SYSTEM

During the first few hours of operation of the central heating
system, check that all radiators are being heated at an even rate.
Should the upper area of a radiator be at a lower temperature than the
base of the radiator, it should be vented by releasing air through the
venting screw at the top of each radiator. Make sure your installer
shows you how to carry out the operation. 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 excessive venting be
required from any radiator, a service engineer should be contacted and
the system corrected.

SEALED HEATING SYSTEM

The appliance will be fitted to a sealed heating system which is
pre-pressurised. Your installer will advise you on the minimum and
maximum pressure that should be indicated on the pressure gauge.
See Fig. 2. Check regularly that this pressure is maintained and
contact your installer or maintenance engineer if there is a permanent
significant drop in pressure indicated on the gauge. If the system loses
pressure it should be re-pressurised as instructed by the installer
(N.B. Maximum pressure 2.5 bar).
CLEARANCES
Your installer will have provided adequate space around the
appliance for safety and servicing. Do not restrict this space by the
addition of cupboards, shelves etc. close to the appliance.
Minimum clearances in millimetres.

ROOM THERMOSTAT

A room thermostat may be fitted for control of the central heating
temperature. It will be located in one room of the home. The method
of setting a room thermostat varies with the type and manufacture.
Refer to the instructions supplied with the room thermostat.

THERMOSTATIC RADIATOR VALVES

If thermostatic radiator valves are to be fitted to the system then
they must conform to the requirements of BS2767:1972. It is advisable
to leave one valve permanently set at maximum to prevent the boiler
short cycling.
