Flue Parts Assembly
All items assemble by a push fit/clamp system. If it is
required to lubricate the seals only Centra Cerin
supplied by the manufacturer or Silicone Grease
should be used.
The pipes should be assembled so the socket end is
always furthest from the Heater.
Flues should be supported by brackets every metre of
run.
Horizontal flues should incline back to the Heater by
3 degrees (52mm in 1000mm)
It is recommended that:
1.
The Installation of the flues are completed before
their connection to the Heater. This will ensure
that any debris that gets into the flues can be
cleared.
2.
That bends in vertical flues are always 45 degrees.
3.
Flues may be reduced in length by cutting. The
inner Flue pipe should be cut so it is 5 to 10mm
longer than the outer Air duct.
4. It will ease assembly if the cut edges are cleaned,
chamfered and greased before assembly.
Wall Terminal
The Horizontal Wall Terminal is supplied with two
rubber wallplates, one for inside and one for the
outside. (
See Fig 3.1
)
If drilled at 3 degrees the core drill diameter required
is 175 mm. If a level hole is being drilled its size will
be determined by the wall thickness.
Wall Thickness
Core Drill diameter
150- 240 mm
175 mm
240- 330 mm
185 mm
330 - 420 mm
195 mm
420 - 500 mm
205 mm
Because of the incline of the flue the height of the
centre of the flue hole on the inside will be determined
by the distance the heater is from the wall.
1. Ensure the required service clearance is available.
2. Fit the 90 degree elbow to the heater and measure
from its outlet face to the wall.
3. Add 52 mm for every 1000 mm distance to
1065 mm.
Example:
Distance maeasured = 480 mm
(52 x 480) / 1000 = 25 mm
Flue centre 1065 + 25 = 1090mm
Roof Terminal
The Vertical Roof Terminal should be fitted in a
minimum of 300mm clear unobstructed space. It is
not permitted to alter the construction of the Terminal,
above the roof line, however the concentric section
below the roof line can be altered to suit the installa-
tion.
Outdoor Terminal
A specific Outdoor Top Terminal must be used
for an outdoor installation.
The Outdoor Top Terminal is a push fit into the Flue
Adapter and locked in position with a clamping ring
(
See Fig 3.2 and 5.0
) with the fastener at the back. If
lubrication is required only Centra Cerin or silicone
grease should be used.
