Arriva Flueing - Rinnai Arriva 752 Installation Manual

Arriva 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 Arriva must be installed with an approved flue system, approved
components are shown in this guide.
General flueing guidelines
Flue clearance to combustibles
- Flue transition (p. 9) - 5 mm.
- Elbow component of the adaption flue kit (ASPKIT03) - 25 mm.
All other Arriva flue components have zero clearance.
Flue cowl clearance
To ensure products of combustion are cleared, adequate clearance
from 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. An
adequate flow of fresh air must exist around the flue cowl following
installation.
Minimum clearances are shown in AS/NZS 5601.1.
Flashings
Flashings to top of chimney structure do not form part of the flue kit and
must be specified.
Flue support
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.
