PARAGON FOCUS RS Installation Instructions
SECTION TEN To Install the Appliance Continued
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 CORGI “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 pipework 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.
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. A minimum clearance of 50mm must be
allowed between the appliance case (rear, top and sides) and the material used to line the
opening. The base of the opening must be non-combustible.

Wrap
the appliance body (top, rear and sides) and both flue tubes with “Rockwool” (50mm
minimum thickness).

Where the duct pipes pass through the inner timber leaf concentric holes 200mm diameter should
be cut around each duct pipe, allowing a minimum 50mm air gap all round each duct pipe. A non-
combustible sleeve 200mm diameter must be fitted to these clearance holes.

To ensure that any condensation formed on the duct pipes does not drip on to the inner wall a
length of galvanised wire must wrapped around each flue pipe and secured in position by twisting
the ends together. Ensure that the twisted ends are located at the bottom of the pipes 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.
Method 2 (For installation into the inner timber leaf of the wall

Find a suitable position between the wall panel frames and carefully open up a hole (minimum
dimension 505mm wide x 605mm x 230mm depth) this will ensure 50mm minimum clearance
around the appliance body Note: the 230mm could be reduced to 200mm if no combustible
material is left between the back of the fire box and the outer skin on brickwork. Careful attention
must be made to securing the damp proof membrane back into position. (Note: To achieve the
minimum depth requirement it may be necessary to deepen the cavity by building up the wall
surface with an appropriate none combustible material.)

Line the exposed cavit
y (top, rear and sides) with an insulation material (20mm “Superlux” or
equivalent) to form a boxed chamber. The base of the opening must be non-combustible.

Wrap the appliance body (top, rear and sides) and both flue tubes with “Rockwool” (50mm
minimum thickness).

Where the duct pipes pass through the inner timber leaf, concentric holes 200mm diameter
should be cut around each flue pipe, allowing a minimum 50mm air gap all round each flue pipe.
A non-combustible sleeve 200mm diameter must be fitted to these clearance holes.

To ensure that any condensation formed on the duct pipes does not drip on to the inner wall a
length of galvanised wire must wrapped around each flue pipe and secured in position by twisting
the ends together. Ensure that the twisted ends are located at the bottom of the pipes and the
wire is centrally located within the cavity.
