The flue system used when installing the heater MUST
comply with the current installation standard AS/NZS 2918.
Full instructions on the installation of the flue will be supplied
with the flue kit. These MUST be adhered to, including the
minimum exit height from the top of the floor protector
being not less than 4.6m, and the minimum exit height above
the roof line of roof ridge as detailed in the instructions.
The flue must be fitted with either of the following:
1)
Rear Flue Shield
–
900mm long, minimum 160° arc,
stainless steel rear flue shield painted black, OR
2)
Solid Flue Shield
–
a full length, solid outer flue shield
(7.75” –
8” diameter) extending from the heater
through into the drop box penetrating the ceiling. The
base of the solid outer shield must be fitted with the
Decromesh Locating Ring supplied with in the heater. A
900mm high external rear heat shield (130mm wide,
needs to be ordered separately) shall be fitted to the
rear of the solid outer shield, positioned 25mm above
the top of the heater and 15mm off the rear of the solid
outer shield, OR
3)
Decro-mesh
–
a full length, half radius perforated
decro-mesh flue shield
(7.75” –
8” diameter)
extending
from the heater through into the drop box penetrating
the ceiling. A 900mm half round inner reflector must be
fitted inside the decro-mesh. Using tin-snips, cut 10mm
tabs into the top and bottom of the inner reflector and
bend out to create an air gap between it and the outer
decro-mesh. The base of the decro-mesh outer shield
must be fitted with the Decromesh Locating Ring
supplied within the heater.
Depending on the supplier, decro-mesh can be one of three
sizes
–
200 mm, 7 ¾ inch, or 8 inch diameter. The
Decromesh Locating Ring will fit the two smaller diameters
but not the 8 inch. In this scenario, snip through the outer
ring with tin-snips, as shown in the diagram below. Bend
the two “arms” in a little so they ends don’t project out
when fitted to the decro-mesh. Ensure that the snipped
section is at the rear of the flue, out of sight.
If the draft is insufficient or periodic down drafting occurs and
the heater smokes or only burns slowly, extending the flue or
fitting a specialized cowl will usually resolve the issue.
