•
cut these lengths from the 150mm diameter pipe and 100mm diameter pipe.
NOTE THE INNER SHOULD BE 15MM
LONGER THAN THE OUTER!
•
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 appertaining to a gas pipe in a cavity. Note the gas feed
must be fitted with an isolation valve.
•
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.
•
Pass the flue terminal through the core drilled hole and check the flue fully engages on the flue spigots.
•
Mark the fixing holes, remove the terminal and drill the wall to accommodate the wall plugs.
•
Run two beads of flue seal or fire cement around the inside of both pipes to ensure airtight seal.
•
Fit the terminal to the wall and fix back with the screws provided.
•
If the flue outlet is fitted below 2m from the floor or a balcony then the flue guard must be fitted.
INSTALLING THE APPLIANCE INTO DEEP REBATED FIRE SURROUND OR DUMMY CHIMNEY BREST.
Additional duct pipe/s will be required.
(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 it 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 (150mm min. for Hole
in Wall installation) 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
565mm.
•
Mark a short horizontal line
so it crosses the centre line
at 438mm from the hearth
level line. This is the centre
point for the flue hole.
•
Using a long masonry drill,
make a pilot hole
completely through the
wall, ensure the hole is
drilled accurately at the
centre and square to the
wall both horizontally and
vertically at the cross point previously marked.
•
Using 150mm (6
”) core drill, cu
t the hole following the pilot hole, drill from the outside of the dwelling through to
the cavity, and from the inside through to the cavity
•
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
•
Lay the hearth or a non-combustible base (for Hole in Wall) so that it is positioned correctly to the horizontal line.
