SECTION 7: FLUE INSTALLATION
7.1 Flue Installation
7.2 Changing Flue and Air Intake Orientation
The heater is sold with horizontal flue and fresh air
connections as standard. If vertical flue and fresh air
connections are required, follow the instructions on
Page 39, Section 16.4 through Page 40, Section
16.5.
The flue must terminate outside of the building.
Flues and air intakes must be a fully sealed system
and correctly sized for the model. Flues should be
assembled as detailed
on Page 14, Figure 7 through
Page 15, Figure 9. The joints between the flue
terminal and the roof or wall must be properly
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 heater does not bear the
weight of the pipes.
For flue termination See Page 14, Figure 7 through
Page 15, Figure 9.
