Rinnai Neo Series Installation Manual page 31

Neo flueing
Every gas fire requires a flue system that will draw effectively and clear
flue products safely under all potential wind and climatic conditions. It
is the responsibility of the installer to ensure the appliance is provided
with an effective flue.
Some guidelines to assist with flue design are detailed below. These
must be read and modified as necessary depending on the installation.
The Neo must be installed with an approved Rinnai flue system.
General flueing guidelines
Inner flue: Clearance to combustibles
Clearance from the inner flue to a combustible material must be greater than 25 mm.
Flue cowl clearance
To ensure products of combustion are cleared, adequate
clearance for the building is required.
The flue cowl should have a 500 mm clearance from any part
of the building. This also applies to steeped and pitched roofs
where the flue cowl should be 500 mm clear of the ridge
line. Adequate fresh air flow must exist around the flue cowl
following installation.
Minimum clearances are shown in AS/NZS 5601.1.
Flue terminal locations
Must be compliant with 'Clearances Required for Flue Terminals'
from AS/NZS 5601.1. The flue is not to terminate under floors or
in a roof space.
Self-supporting flue
The weight of the flue system should not be supported by the appliance—it should be self-
supporting. Supporting the flue is usually completed during the framing stage with flue supports
or straps within the cavity.
Shared flues
Gas appliances must not be connected to a chimney or flue serving a separate fuel burning
appliance.
