www.charltonandjenjick.co.uk 7 LT6935 (ISS 4)
SECTION TWO: Introduction(Users Instructions)
The INFINITY 480 BF is an inset room sealed decorative fuel-effect gas appliance designed for use in
locations that do not have a conventional chimney. The appliance must be installed against an outside
wall because the air to support combustion is taken from the outside and the products of combustion are
expelled to the outside.
The appliance incorporates a safety device in the form of a FLAME SUPERVISION DEVICE, which
constantly monitors the flame and will cause the gas to be switched off if the flames are extinguished
for any reason. THIS DEVICE MUST NOT BE OVERRIDDEN. If this situation occurs on a regular basis
have the appliance checked by a qualified engineer. The problem may be due to a blocked or restricted
flue.
Before removing the, trim, glass shapes for cleaning the fire should be turned off, and left to cool down.
NOTE: In use some discoloration of the components will take place in the combustion box, this is normal,
but can be kept to a minimum if the shapes are placed correctly (i.e. after cleaning). See Section 4.
As with all heating appliances certain areas (Working Surfaces) become very hot when the appliance is
in use.

Siting the Appliance Continued (Installation Instructions)
Please note with early cavity wall design prior to 1970. The minimum depth requirement may well be difficult to
obtain. This could result in the need for the fire box to be spaced further from the internal surface of the plaster and
to achieve this larger rebated surround maybe necessary. (Appropriate measures should be taken when installing in
to a working flue system I.E out through an existing chimney)
Ensure that gas supply is suitably sited
Check with the supplier or manufacturer that
the surround meets 1500C minimum rating
(attention should especially be given to man
made materials such as resin).
When installing in a timber framed dwelling
reference must be made to the specific
installation requirements stated in
Clearance to Shelf
Minimum clearance from hearth or base of opening
to underside of combustible shelf should be
830mm provided the shelf depth is 75mm (3”).
This gives a minimum clearance above the
appliance of 140mm. For a shelf of 150mm (6”) the
minimum height above the hearth or base of opening
must be 910mm. This will give a minimum clearance
above the appliance of 220mm.
Clearance to Sides of Fire
Minimum width between vertical sides of combustible surround should not be less than 875 mm provided fire is
central to the surround and sides do not project more than 150 mm. When vertical side forward projection is increased
by 12.5 mm add 50 mm to inside width of surround.

SECTION NINE: Install The Appliance (Installation Instructions)
INSTALLING THE APPLIANCE INTO CAVITY WALL WITH A FIREPLACE
Ensure it is a suitable outside wall constructed of non-combustible materials and that the flue position meets
the requirements previously described in Section 7.
Mark a vertical line on the wall at the intended centre of the appliance and fireplace.
Using the table below mark the measurements horizontally across the vertical centre line.
Mark out the width of the opening for the appliance between 560-575mmcentral to the centre line.
Mark the position for the lintel above the top horizontal line.
Using a long masonry drill, make one pilot hole completely through the wall at position B. Ensure the hole is
drilled accurately at the centres and square to the wall both horizontally and vertically at the cross
points previously marked.
Cut out the brickwork of the inner skin of the cavity wall for the lintel, and fix the lintel in place.
Cut out the brickwork under the lintel, between the two outside vertical lines and base line into the cavity.
The cut out will not extend to floor level creating a base for the appliance to sit on.
Create a level base in the cut out using non-combustible material.
Ensure the cut out width is square and try the appliance into the opening.
Using a 150mm core drill from outside cut a hole following the pilot hole. Drilling from the outside through to
the cavity will give a good finish on the outside wall.
Remove any cavity insulation from the cut out opening and for a further 100mm into the cavity gap each
side and above.
Pack “Rockwool”around the sides, top and bottom of the opening into the cavity for a depth of 100mm.
