Installing The Flue - Nectre Fireplaces Big Bakers Installation Instructions

4. INSTALLING THE BY-PASS DAMPER
Before installing the flue, the by-pass damper handle must be
fitted. The handle is supplied inside the firebox.
Insert the threaded end of the handle into the 10mm hole on
left side of heater. Looking down through the flue spigot
locate the threaded end of the handle with the extended nut
attached to the by-pass damper. Screw the handle all the way
into the nut until tight.
The position of the handle should be at approximately 11
o'clock when the damper is open, and 1 o'clock when the
damper is shut.

5. INSTALLING THE FLUE

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 a 900 mm long, minimum 150°
arc, stainless steel rear flue shield.
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.
6. INSTALLING FIRE BRICKS
The heater comes with 4 fire bricks (230 mm x 115 mm x 38
mm) and a 480 mm long brick retainer as well as two
triangular bricks (50 x 70 x 250 mm) for the front.
Place the four fire bricks upright, up against the rear wall of
the firebox.
Place the U-shaped brick retainer over the top of the bricks
such that the bricks fit inside the U-section. This will hold
them in place.
Place the triangular firebricks at the front of the firebox
beneath the door opening.
(Note: the firebricks may already be in place upon arrival of
the new appliance.)

7. INSTALLING FIREBOX SIDE SHIELDS
The heater comes with two 8 mm thick sacrificial shields
fitted to the sides of the firebox to protect the walls of the
firebox.
Lugs on the shields allow them to hang over the angled cut-
out on the sides of the firebox along the top.
(Note: the firebox side shields may already be in place upon
arrival of the new appliance).
