FITTING TO PRE-CAST FLUES
When installing this appliance into pre-cast flues, always ensure that the
spigot restrictor baffle has been removed.
To install the fire box in to pre-cast flue starter blocks, there must be at least
180mm from the mounting face of the fire to the rear of the pre-cast flue
starter block to allow sufficient space for debris collection. It is important to
consider this depth when choosing a fire surround as the thickness of the fire
surround must be sufficient to give a total depth of at least 180 mm to the rear of
the starter block, otherwise there will be insufficient depth. This fire has been
designed to fit standard 100mm pre-cast starter blocks with 3 inch rebated
surrounds and a 10mm plaster wall covering. It is important to ensure that the
pre-cast flue is in good condition and is free from extruded mortar or sealant from
between the flue blocks.
This appliance has been tested for use in a pre-cast flue block complying
with BS EN 1858. In accordance with BS EN 1858, pre-cast flues built with
directly plastered faces (front or rear) are not correctly installed as to ensure
proper operation with any type of gas fire. In some instances of this flue
construction, temperature cracking of surface plaster may occur through no
fault of the appliance. An air gap or some form of insulation material should
be installed to prevent normal flue temperatures from damaging wall
surfaces.

SPILLAGE MONITORING SYSTEM
This appliance is fitted with an atmosphere sensing spillage monitoring system in
the form of an oxygen sensing pilot. This is designed to shut the fire off in the
event of a partial or complete blockage of the flue causing a build up of
combustion products in the room in which the fire is operated. The following are
important warnings relating to this spillage monitoring system :-
1.9.1
The spillage monitoring system must not be adjusted by the installer.
1.9.2
The spillage monitoring system must not be put out of operation.
1.9.3
When the spillage monitoring system is exchanged only a complete
original manufacturers part may be fitted. It is not possible to replace
individual parts on the pilot system on this appliance, only a complete
pilot assembly (including the thermocouple) may be fitted.
