GENERAL INFORMATION

Read these instructions carefully to get the best

from your appliance.

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. Repeated venting will reduce the quantity of

water in the system and this must be replenished

for safe and satisfactory operation of the appliance.

When excessive venting or water leaks are found

in the system you must contact a service engineer

to inspect the installation and rectify any fault.

Only use additives compatible with the appliance

and system. Use of incompatible additives can cause

damage and will invalidate the appliance guarantee.

Sealed eating systems:

Where the appliance is fitted to a sealed heating

system your installer will inform you of the minimum

and maximum pressure which must be indicated

on the pressure gauge.

Regularly check the pressure is maintained and

contact your installer or maintenance engineer if

there is a noticeable, permanent drop in pressure.

If the system loses pressure it should be

repressurised and the cause of the fall investigated.

CONDENSATE:

This is a high efficiency appliance using condensing

technology which will under normal operation

produce a regular discharge of condensate to drain

and at times, give out a plume of water vapour from

the flue terminal.

ROOM THERMOSTAT:

A room temperature controller must 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.

BOILER LOCATION:

This boiler is only suitable for installing internally

within a property at a suitable location onto a fixed

rigid non-combustible surface at least the same size

as the boiler and capable of supporting the boiler

weight.

The boiler is not suitable for external installation

unless a suitable enclosure is provided.

Roof space installations must fully conform to

BS5410 part 1 section 4.6.9

VENTILATION:

Air vents must be functional at all times and the air

supply must not be restricted or contaminated.

The appliance clearances must meet the minimum

shown opposite for servicing and venting purposes.

* If this clearance is less than 75mm the flue 'knock-

out' panel sections must be removed to improve

air circulation and cooling.

Do not place clothes or objects to hinder the air

circulation required by the appliance.

Conventional flue appliances require an adequate

supply of fresh air which must be delivered to the

boiler for combustion purposes through a permanent

inlet, such as an air brick, into the area where the

boiler is situated.

If a cupboard or compartment which is to be used

for storage or airing is built around the appliance

after installation there must be a non-combustible

partition around the boiler. Further information can

requirements.

Venting compartments:

 Ventilation must be provided for boilers fitted

into compartments as described in BS 5410

 A minimum of 2 air vents must be fitted, one at

low level and another at high level onto the same

wall using the same air for circulation.

Free air must not be taken from a room or internal

space containing a bath or shower and must not

communicate with a protected area such as a

hall, stairway, landing, corridor, lobby, shaft etc.

 Air vents must allow access for clean free air

and must be sited to comply with the flue terminal

position requirements.

 Air ducting runs must not exceed 3m.

 Low level air vents must be less than 450mm

from the floor.

A warning label must be added to the vents with

a statement to the effect: ''Do not block this vent.
