Installation Manual
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 35 for more information.
FLUE TERMINAL LOCATION
The flue terminal should be positioned away from flammable
materials.
Ensure that the location of the flue terminal can comply with the
requirements of AS/NZS 5601, Fig. 6.2 which is reproduced below.
Clearances for Natural Draft apply.
* AS/NZS 5601 was current at the time of printing this manual, but may have been
superseded. It is the installers responsibility to ensure that the current version of this
standard is used.
