FLUE INSTALLATION CONFIGURATION
TYPES OF FLUE INSTALLATION
The types of suitable flue configurations are shown above. Other flue configurations are not suitable.
Suitable flue components are shown below. Other flue components not shown are not suitable. For
full details regarding flue assembly and installation refer to the 'Simpson Duravent'® "DirectVent Pro"
Installation Instructions supplied with the flue components.
A 'flue restrictor plate' needs to be installed inside the appliance for some flue configurations. This is
to ensure the correct amount of 'natural draft' can be achieved. Refer to the section "CONNECT FLUE
AND INSTALLING THE FLUE RESTRICTOR" on page 28 for more information.
FLUE TERMINAL LOCATION
The flue terminal should be positioned away from
flammable materials.
WARNING
Ensure that the location of the flue terminal can comply
with the requirements of AS/NZS 5601 2010, Clause 5.13,
Fig. 6.2 which is reproduced below. Clearances for Natural
Draft apply.

NOTES:
1
Where dimensions c, j or k cannot be achieved an equivalent horizontal distance
measured diagonally from the nearest discharge point of the terminal to the opening
may be deemed by the Technical Regulator to comply.
2
See Clause 6.9.4 for restrictions on a flue terminal under a covered area.
3
See Figure J3 for clearances required from a flue terminal to an LP Gas cylinder.
A flue terminal is considered to be a source of ignition.
