SECTION 6: FLUE INSTALLATION
6.1 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 29, Section 15.4.
6.2 Flue Installation
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 9, Figure 5 through
Page 10, Figure 7. 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 9, Figure 5 through
Page 10, Figure 7.
