SECTION TWO Introduction
The INFINITY 880 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.

INFINITY 880 BF Installation Instructions
SECTION SEVEN Siting the Appliance Continued
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.
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 1040mm 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 1120mm. 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.
*Please note - Appropriate measures should be taken when installing into a working flue
system i.e. out through an existing chimney *
