It is the law that all gas appliances are installed by
a competent person, in accordance with the gas
safety installation and to the current Gas Safety
(Installation and Use) Regulations B.S.5440:2-(2000).

All registered installers carry a Gas Safe Register ID card
and have a registration number. Both should be recorded in
your boiler Log book. You can check your installer’s
registration at www.gassaferegister.co.uk.

ESCAPE OF GAS
Should a gas leak be suspected, contact your gas
supplier without delay.

GAS EMERGENCY NUMBER: 0800111999

Do NOT search for gas leaks with a naked fl ame.

WARNING: This appliance must be earthed.

1.1 INTRODUCTION

Please carefully read the information given in this
booklet to help you gain maximum control from your
appliance with minimum trouble and cost.

Your Ravenheat Condensing Low Nox combination boiler
has been designed to supply your Central Heating and
Domestic Hot Water directly from one unit.
When Central Heating is operating, the circulation will be
interrupted when Domestic Hot Water is being drawn off
(domestic hot water has priority).
This will normally not affect the level of Heating.

PLEASE NOTE:

Due to the high effi ciency of this appliance and resulting

low fl ue gas exhaust temperature a white plume of
condensation vapour (cool steam) will be emitted from the
fl ue outlet terminal, this is quite normal. It will be
particularly evident during periods of low outdoor
temperature or when the boiler is working at its optimum
performance (Plume Management kits are available on
request).

IMPORTANT:
In the unlikely event of the exhaust fl ue gases exceeding

the overheat temperature setting, the boiler operation will
be stopped to prevent damage to the appliance.

1.2 CLEARANCES AROUND THE APPLIANCE

Side clearance:

The position of the appliance must provide a
minimum clearance of only 5 mm as the side panels
do not require removing for servicing.

However, if the option is preferred to remove the
panels then a minimum clearance of 55 mm is
required.

Top clearance:

The top clearance should be a minimum of
125 mm.

Bottom clearance:

A minimum bottom clearance of 80 mm is

required between the appliance and any surface,
though 150 mm is preferred whenever
possible.

Front clearance:
A minimum of 450 mm is required in front of
the appliance for access during servicing, the
front clearance can be reduced when installed
in a cupboard to 25 mm from the access door.
