INFINITY 890 BF Installation Instructions
SECTION NINE To Install the Appliance Continued

Using 125mm (5
”) core drill cut two holes following the pilot holes. Drill from the outside through to
the cavity to give a good finish on the outside.

Remove any cavity insulation from the cutout opening and for a further 100mm into the cavity gap
each side and above.

Pack “Rockwool” around the sides and top of the opening into the cavity for a depth of 100mm.
Also put some behind the firebox if space is available.

Lay the hearth if required so that it is positioned correctly to the horizontal line.

Offer the appliance into the opening and mark through the gas pipe entry hole (see connecting the
gas supply section).

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 and fill any space behind the appliance with
“Rockwool”.

Complete the gas connection (see connecting the gas supply later in this manual).

Drill the four fixing holes through the hole in the flange of the appliance and fix back using plug
and screws.

Fit the outer wall terminal plate, with the “Rockwool” gasket sandwiched between it and the wall,
with the double spigot at the top so that it seals to both the flue pipe and the air duct, (use flue
seal or fire cement to ensure air tight seal, it must not obstruct the flue).

Drill through the four holes in the outer wall terminal plate and fix back to the wall using plugs and
screws.

Position the outer terminal cover and fix to wall terminal plate with the four screws provided.

If the flue outlet is fitted below 2m from the floor or a balcony then a flue terminal guard must be
fitted.
