CAVITY / FRAMING PREPARATION
Refer to Table 3 for the minimum cavity dimensions and temporary lintel height measurements, until the
convector box and flue system is installed.
Note: Temporary lintel height is measured from finished floor protector level.
Ensure suitable air vents (min. 2 x 80mm diameter or equivalent) in place to vent firebox cavity - these maybe
located in the floor or in the side wall space; make allowance (min. 2 x 80mm diameter or equivalent) at the
top of the chimney chase, See Fig. 3. Ensure vents are bird and vermin proofed.

1. Fit and seal gather, using fire cement (exhaust cement) and bolts (supplied), to the convector box. Note:
Pop rivet back of gather to convector box if required.
2. Locate and position convector box and gather in cavity.
3. Attach rock wool to the sides & back of the convector box and gather. DO NOT BLOCK OFF the air entry
between the inner flue pipe and flue pipe casing or the air circulation between the vent holes in the cavity.
4. Drill a hole in the convector box for the Gas Line/ Wall switch cable (3m Supplied) or remove 20mm
knockout discs.
5. A minimum 300mm non combustible floor protector (hearth) is in front of the convector box. Ensure that
the base of the fire sits on the finished hearth level.

CHIMNEY CHASE AIR VENTILATION
1. Install first length of flue pipe crimped end down, inside gather collar. Rivet flue pipe in 3 places around
gather collar. Place bottom flue spider bracket around gather flue pipe collar, secure in position by
tightening up coach bolt/screw (supplied).
2. Install second length of the flue pipe crimped end down and fix by riveting in at least 3 places around the
flue pipe joint.
3. Install first length of the flue pipe casing by positioning on installed bottom flue spider bracket crimped
end up.
4. Position flue spacer at the flue pipe joint.
5. Repeat steps 1 - 4. As per manufacturers recommendation, the flue pipe shall extend not less than 3.6m
above the fire box.
6. The flue is required to be at least 500mm above the nearest point on any part of the buildings roof and
neighbouring buildings if within a 3m radius. Refer to NZS 5261:2003; 2.6.13 for further information.
7. The last length of flue pipe needs to extend past the flue pipe casing by at least 150mm or flush with the
top of the casing cover spigot when fitted - sizing/measuring and cutting down should be carried out prior
to the flue pipe casing being fitted over the flue pipe.
8. Before fitting casing cover, place the spider in opposition with the spider post facing down between the
flue pipe and flue pipe casing. Secure spider in position. Place the casing cover over the flue pipe, press
down firmly onto the spider. Check airway around the casing cover is clear, then secure in position using
three stainless steel rivets.
9. Fit cowl to top of flue - DO NOT RIVET IN POSITION. In high wind areas, it is recommended that the cowl
be secured in position with a stainless steel self tapping screw, this will enable the cowl to be removed for
cleaning. Discuss Bird Proofing needs with your installer. N.B. in extreme wind areas it may be necessary
to consult The Fireplace Ltd or your local agent for further technical assistance.
10. If flue is concealed in a chase, allow for air vents (2 x 80mm diam. or equivalent) at the highest possible
point on the chimney chase or alternatively, allow a min 25mm air space between the casing cover spigot
and the outer casing. Refer to Figure 7 and 8.
