INFINITY 890 BF Installation Instructions
SECTION NINE To Install the Appliance Continued
INSTALLING THE APPLIANCE INTO A DUMMY CHIMNEY BREAST. (
When installing
in a timber framed dwelling reference must be made to the specific installation requirements stated
later in this
Section ‘Installing The Appliance In Timber Framed Dwelling’
) .

Ensure there is a suitable outside wall constructed of non-combustible materials and that the flue
position meets the requirements previously described.

Mark a horizontal line on the wall at the intended hearth surface or appliance base height. If
required the skirting board must be cut away from behind the fire.

Mark a vertical line on the wall at the intended centre of the appliance up from the horizontal line
for a height of 430 mm.

Mark a short horizontal line so it crosses the centre line at 75mm above hearth level line. This is
the centre point for the Air Duct pipe hole.

Mark a short horizontal line so it crosses the centre line at 355mm above hearth level line. This is
the centre point for the Flue Duct pipe hole.

Using a long masonry drill, make pilot holes completely through the wall. Ensure the holes are
drilled accurately at the centres and square to the wall both horizontally and vertically at the cross
points previously marked.

Using 125mm (5
”) core drill cut the holes following the pilot holes. Drill from the outside of the
dwelling through to the cavity, and from the inside through to the cavity for best results.

Remove any combustible material that may be present if the rear of the appliance is contacting
the wall i.e. ensure no battens etc., behind dry lining in the area shown around the flue and top of
firebox. Always remove a 25mm (1”) area around the flue if plasterboard etc is present anyway.

Lay the base (for Hole in Wall) so that it is positioned correctly to the horizontal line.

Temporarily position and construct a dummy chimneybreast as required, avoiding combustible
materials coming in close proximity to the appliance or the flue.

Offer the appliance into the opening and mark through the gas pipe entry hole (see connecting the
gas supply later in this manual).

Pass a tape measure through the core-drilled holes and record the distance from the spigots to
the surface of the outside wall. Include the length of the spigots themselves in this measurement
and increase both
the recorded distances by 15mm (5/8”) each for the engagement allowance.

Cut the lengths from the one 535mm flue pipe provided, if the length is longer than 267.5mm you
will require an extra flue pipe.(535mm standard or 1000mm optional)

Remove the appliance from the opening, and position the gas supply (see connecting the gas
supply later in this manual), taking account of the relative gas regulations regarding a gas pipe in
a cavity (sleeving and sealing etc). Note the gas feed must be fitted with an isolation valve.

Position and seal the pipes to their respective spigots on the rear of the appliance (use flue seal
or fire cement to ensure airtight seal, it must not obstruct the flue).

Peal the backing off the length of foam seal and affix to the rear outer edge of the appliance
flange.

Push the appliance back into the opening.

Complete the gas connection (see connecting the gas supply later in this manual).
