- With the “T piece, flexi flue and bracket” now assembled, position
this pre-assembly into the “RIGHT HAND SIDE” of the chimney
cavity with the centre height of the “BRACKET” 300mm above the
base of the chimney cavity, and the two holes to be drilled into
the masonry through the brackets return fold 270mm back from
the chimney cavity entrance. Secure using two 6mm dynabolts or
equivalent masonry anchors.
2. Smear an adequate amount of silicone sealant inside the top/
un-crimped ends of the vent pipes. Secure the vent pipes together
ensuring the vent seams are in line. Vent pipe joints must be fully
compressed to ensure a good seal, and then riveted together at
3 even points around the vent join. For installations where extra
lengths of vent pipe are required, or when the weather is poor, it
will be easier to assemble the vent pipe lengths as they are lowered
into the masonry chimney. Prior to installing the assembled vent
pipe into the masonry chimney cavity, take careful note to ensure
there are no overhead power lines in close proximity. Lower the
vent pipe into the masonry chimney, with the crimped end entering
the top of the chimney cavity first.
3. From inside the cavity hold the lower section of the vent pipe in its
approximate position and measure from the centre of the vent pipe
to the centre of the top outlet of the “T” piece. Smear an adequate
amount of silicone onto the slip section of the offset to ensure a
good seal and then adjust the telescopic offset to the centre to
centre measurement from the “T” piece to the vent pipe. Rivet the
offset in three locations around its circumference. (If the offset is
used in its fully compressed form, it will be necessary to modify the
end of the male slip section otherwise it will restrict the internal
diameter) Apply a liberal amount of silicone around the crimped
end of the lower vent pipe, lift the assembled vent pipes up high
enough to allow it to be inserted into the un-crimped end of the
offset, rivet together at 3 even points around the join, then fit the
lower crimped end of the offset into the “T” outlet, silicone and rivet
into position.
4. Making your way back onto the roof secure the outer casing with
suitable fasteners and weatherproof seal to the masonry chimney
top with mortar or silicone. A masonry chimney flashing plate is
recommended and will need to be fabricated with an upturn to
secure the 150mm outer casing. Note: The top of the outer casing
must be “level” ( + or - 10mm) with the top of the 100mm stainless
steel vent pipe. Place the 100mm cowl over the vent and screw to
the 150mm casing and secure with S/S screws.
5. Moving back into the home, mark a line 320mm from the front
wall of the fire place cavity opening out into the room, this will
give a 28mm gap for the facia to slide into once the pellet fire is in
position.
6. Position the rear of the pellet fire just out of and to one side of the
opening to allow maximum access, pull the flexi pipe out to the fire,
smear a liberal amount of silicone inside the pre-bent end of the
flexi flue and push over the pellet fire outlet then screw in place.
7. Fit the fascia and MX3 controller as per the instructions supplied
with the fascia.
8. Slide the unit back into the cavity until the mark lines up with front
of the base, TAKE CARE NOT TO DAMAGE THE EXHAUST FAN
WHICH PROTRUDES OUT TO THE LEFT.
9. Open the pellet fire door drill and fit 2 suitable fasteners to fix
the unit to the floor, if using masonry fasteners use a rawl bolt or
similar so that the fire can slide out over them when the bolts are
removed.
