If the appliance is to be sited near a disused or unserviceable fireplace served by a natural draught flue then the old flue must be
sealed off. It will be necessary to ventilate the old flue to prevent condensation and dampness forming, however any air vent used
to ventilate the old flue must not be sited within 500mm of this appliance. If the flue can be ventilated to the outside of the build-
ing then this is usually the best solution. If in doubt then advice should be sought from a local building control officer. The appli-
ance is designed to be wall mounted. If the appliance is to be mounted on a newly fabricated area of wall that also serves the pur-
pose of sealing off the old flue then it is very important that there are no holes, gaps or otherwise in this wall that will allow
draughts from the old flue to enter the room, especially directly behind the appliance. Such draughts could affect the perform-
ance of the ODS system and result in nuisance cutting out, for example. If the gas supply pipe is to enter the appliance from the
rear, i.e. emerge from the wall behind the appliance, then any hole in the wall from which the pipe emerges must be tightly sealed.
Any existing under grate draught device should be sealed off to prevent loss of heat or creation of draughts. It is possible to install
the appliance onto certain types of combustible materials - see section entitled 'Clearances to combustible materials'.
• P23 and L23 models :The room size should be a minimum of 23m3 (e.g. 10'1" x 10'1" x 8').
• L30 models :The room size should be a minimum of 30m3 (e.g. 11'6" x 11'6" x 8').
This is to allow adequate circulation of air and ensure the correct operation of the fire.This volume may include adjacent spaces
but these spaces must not be separated by a door. Note : To calculate a room size in cubic metres (m
3
) divide the room volume in
cubic feet (ft3) by 35.3.
This appliance may be installed in any room in the home except bathrooms or bed-
rooms. Upon implementation of BS 5871 pt 4, installation in bedrooms is then permit-
ted. If the appliance is to be fitted in a bedroom then an electronic carbon monoxide
detector complying with the current edition of BSEN 50291 must be installed in the
same room as the appliance. For maximum safety it is recommended that such device
is continuously (mains) powered and arranged in such a way that the gas supply to the appliance is isolated in the event of an
alarm.The selection and installation of such device shall be in accordance with the current edition of BSEN 50292, and the user
must be briefed regarding the use and maintenance of such a device. Installation in living rooms is common, however other rooms
such as kitchens, dining rooms and hallways are permitted, providing a suitable natural gas supply is available, and rooms sizing and
ventilation requirements are strictly adhered to (see sections 3.1 and 4.1).
