SECTION 6: FLUE INSTALLATION
6.1 Flue Installation
The flue must terminate outside of the building.
Flues and air intakes must be fully sealed and
correctly sized for the model. Flues should be
assembled as detailed on Page 10, Figure 4 through
Page 12, Figure 8. The joints between the flue
terminal and the roof or wall must be sealed. If the
flue passes through a wall or ceiling of combustible
material, it must be enclosed by a sleeve of non-
combustible material and be separated from the
sleeve by at least a 25 mm air gap.
Flues and air intakes must be adequately
supported so that the DualAir
bear the weight of the pipes.
For flue termination See Page 10, Figure 4 through
Page 12, Figure 8.

Room Sealed.
The heaters are designed to be installed as room
sealed appliances. The flue and air intake are run as
separate pipes to the concentric wall or roof
terminal. See Page 12, Figure 8.
6.3 Type B
Appliance

The flue must terminate outside the building and be
fitted with a low resistance terminal.
See Page 10, Figure 4 through Page 12, Figure 7.
6.3.1 Air Intake Terminal Cover
For Type B
appliance installations, an air intake
22
terminal cover is an available option. The cover is
scored flat sheet metal that must be bent into shape.
See Page 12, Figure 7. Remove and retain the
screws for the air inlet spigot. Use these screws to
attach the cover in position over the spigot.

6.4 Converting from Top to Side Terminations for
Flue and Air Intake
1. Remove the control section lower door and
upper panel. See Page 11, Figure 5 through
Figure 6 for details.
6.4.1 Flue Conversion
1. Remove the inner and outer flue spigots from
the top. Retain the spigot and internal seal.
2. Disassemble the flue back to spigot "A". See
Page 11, Figure 6. Ensure all seals are still in
place.
3. Fit 90° bend directly into spigot "A" pointing
forwards.
4. Cut a 90 mm length from the 360 mm flue that
was removed.
5. Attach this piece to the 90° bend, then attach
the inner spigot that was removed.
6.4.2 Air Intake Conversion
1. Remove the flexible hose from the air intake
spigot.
2. Remove the spigot from the top.
3. Move the blanking plate from the upper panel
(previously removed) to the top to cover the
original flue and air intake holes.

ible hose through the upper hole and aligning
the flue with the lower hole.
