To get the best from your appliance please read

these instructions carefully.

SEALED HEATING SYSTEMS

If the appliance 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.

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 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.

If the 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

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 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 regularly, by a

syphon within the boiler, to drain.

CLEARANCES - VENTILATED COMPARTMENT

Your installer will have provided adequate

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.

GENERAL NOTES

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

It is recommended that this type of valve is

fitted to all but one of the radiators (or at least

those in the sleeping accommodation). The

remaining radiator, which must be where the

room thermostat is located, should be un-

controlled and must be left open. The

thermostatic radiator valves should conform to

the requirements of BS2767:10.
