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 followed closely, 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 – 900 mm long, minimum 160
° arc,
stainless steel unpainted
rear flue shield, OR
2)
Decro-mesh – a full length, half radius perforated
decro-mesh flue shield extending from the heater
through into the drop box penetrating the ceiling. A
900 mm 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.
If the draft is insufficient or periodic down drafting occurs
and the heater smokes or only burns slowly, extending the
flue or fitting a specialist cowl will usually resolve the issue.
Flue Spigot Heat Reflector
A flue spigot heat reflector is supplied inside the heater. This
must be fitted to the flue spigot on the heater. The three lugs
on the reflector hang inside the flue ring (spigot) with the
reflector orientated at the rear of the heater.
This device reflects the heat radiating from the flue spigot on
to the rear wall.
The Nectre MK2 LE comes with 9 full size bricks (234(h) x
118(w) x 40(d)mm) and 2 half size bricks (234(h) x 59(w) x
40(d)mm).
Raise the brick retainer (supplied inside the firebox) and start
standing the bricks up against the rear and sides of the
firebox as shown in the diagram below.
Once bricks are in, fit the retainer over the top to hold them
in place.
