1. Refer to the minimum framing dimensions as per Table 4 / Fig 3. Allow a temporary 1200mm lintel
height, until the convector box and flue is installed. Install front nogs on edge to increase chimney
chase dimension.
2. For timber frame, use 6mm Hardiflex board to line the FLOOR, REAR AND SIDES of framed cavity of
framed cavity to be taken to a minimum height of 1200mm from the firebox base.
3. Air Vents to be minimum cross sectional area of 5000sq.mm in total. Use 100 x 50mm air vent or similar
each side of the firebox. For wooden floors locate in floor, for concrete floors locate in walls. All air vents
to be bird and rodent proof.
4. If intending to recess the firebox, the maximim recess value is 100mm. Refer to Fig. 7.
5. If a On/Off Wall Switch is being installed, a power cable (3m supplied) must be run from the on/off
switch to the firebox. Gas Models 1050, 1200 & 1500 are operated by a Millivolt power source. DO NOT
connect a 240V supply to these gas burners (see table 2 for full details).
If a wall switch is being installed for the 700 and/or 850 models, these are operated by 240V AC and
require an electrician to wire, connect and test.
Under no circumstance is the width of the vertical margin legs to be less than 50mm and the height
of the margin lintel to be less than 200mm (see Fig 4).
Where an internal wall board finish is required around the fire, ensure allowance is made to place non-
combustible internal wall lining (eg: Promina, Supalux, Eterpan) shown shaded. Directly touching the firebox
with any board or plaster finish will cause cracking from heat expansion. Allow 2mm minimum space away
from the firebox.

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. Earthquake restraints holes are located under the cover where the receiver and battery pack are situated.
4. 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.
5. Drill a hole or use the knock outs in the convector box for the Gas Line and if a wall switch is being
installed for the cable.
6. A minimum 300mm non combustible floor protector (hearth) is recommended in front of the convector
box. Ensure that the material used is level with the convector box base.

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 Ph: 0800 843 347.
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 8 and 9.
