Installation Instructions
SECTION NINE To Install the Appliance Continued

Drill the four fixing holes through the holes in the flange of the appliance and fix back using plugs
and screws.

If the flue outlet is fitted below 2m from the floor or a balcony then a flue terminal guard must be
fitted.
TIMBER FRAMED DWELLING
This method allows for installation in timber frame buildings. Where removal of any part of the
inner timber leaf of the wall is involved the structural integrity of the wall must be maintained
and the advice of your local Building Control Department should be sought. If the property is
under N.H.B.C. cover, it is advised that their advice should also be sought. Reference should
be made to the British Gas Publication DM2 "Guide For Gas Installations In Timber Frame
Housing" or GAS SAFE
“Gas installations in Timber Frame Buildings” ISBN1-902632-30-3
Special attention must be paid to the location of the studwork frames of the inner leaf and the
appliance positioned accordingly. Electrical cables and pipe work that run within the inner timber leaf
must also be located and taken into account when positioning the appliance.
The following methods of installation may be adapted for use in timber frame buildings providing
extra care is taken to protect combustible materials from contact with hot surfaces or build up of heat.
Method 1 (For installation into a extended fire surround or false chimney breast)

An insulation material (20mm “Superlux” or equivalent) must protect all combustible surfaces
(including plasterboard) situated within the opening.

Where the flue duct passes through the inner timber leaf a concentric hole 200 mm diameter
should be cut around the duct pipe, allowing a minimum 25mm air gap all round the duct pipe. A
non-combustible sleeve 200mm diameter must be fitted to these clearance holes. Sheet metal is
usually suitable.

To ensure that any condensation formed on the duct pipe does not drip on to the inner wall a
length of galvanised wire must wrapped around the flue pipe and secured in position by twisting
the ends together. Ensure that the twisted ends are located at the bottom of the pipe and the wire
is centrally located within the cavity.

The vapour barrier on the back of the inner timber leaf should be carefully cut and fixed to prevent
ingress of damp into the plasterboard layer.
