INSTALLER GUIDE

4.2 Ventilation requirements.

Normal adventitious ventilation is usually sufficient to satisfy the ventilation
requirements of this appliance. In GB reference should be made to BS 5871 Part 2
and in IE reference should be made to the current edition of IS 813 "Domestic Gas
Installations" which makes clear the conditions that must be met to demonstrate that
sufficient ventilation is available.

4.3 The Atmosphere sensing device (ASD).

The appliance is fitted with an A.S.D (Atmosphere sensing device). If the appliance
closes down after a period of operation for no apparent reason, the consumer should
be informed to stop using the appliance until the installation and appliance have been
thoroughly checked. The A.S.D will shut the appliance down if an unacceptable
amount of harmful products of combustion accumulate. Under no circumstances
should the A.S.D be altered or bypassed in any way. Only a genuine manufacturer's
replacement part should be fitted. The individual A.S.D components are not
replaceable.

4.4 Fireguard requirements.

A fireguard complying with BS 8423 should be fitted for the protection of young
children, the elderly, the infirm and pet animals.

4.5 Room considerations.

4.5.1 This appliance must not be installed in any room that contains a bath or shower
or where steam is regularly present.
4.5.2 An extractor fan may only be used in the same room as this appliance, or in any
area from which ventilation for the appliance is taken, if it does not affect the safe
performance of the appliance. Note the spillage test requirements detailed further on
in this manual. If the fan is likely to affect the appliance, the appliance must not be
installed unless the fan is permanently disconnected.
4.5.3 Note that soft wall coverings (e.g. embossed vinyl, etc.) are easily affected by
heat. They may scorch or become discoloured when close to a heating appliance.
Please bear this in mind when installing.

4.6 Chimney preparation.

4.6.1 If the appliance is intended to be installed to a chimney that was previously
used for solid fuel, the flue must be swept clean prior to installation. All flues should
be inspected for soundness and freedom from blockages.
4.6.2 Any chimney damper or restrictor should be removed. If removal is not possible,
they must be secured in the open position.
