GENERAL FLUEING GUIDELINES
The following diagrams illustrate the flue installation options that are available for the Rinnai
SS850 Heaters. ONLY the genuine Rinnai flue is certified as part of the installation requirements.
WARNING
ONLY an authorised person MUST install, service and remove the Rinnai SS850 and heater and
flue system.
Only the flue system components described in this Manual are suitable and MUST be used. 'DO
NOT USE AN UNLINED MASONRY CHIMNEY AS THE FLUE FOR THIS APPLIANCE'.
Components that are not described in that manual, whether manufactured by Rinnai or otherwise,
are NOT compatible and MUST NOT be used.
Rinnai appliance warranty conditions may be voided if non Rinnai Flue Components are fitted.
AS/NZS 5601 "GAS INSTALLATIONS" requires that flue components be supported independently
of the appliance.
Flueing options for the SS850 depending on the installation:
•
False Fireplace - coaxial flueing
•
Masonry colinear flueing
Flexible aluminium flues that come directly off the fire.
Self-supporting flue - False Fireplace
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.
Wall straps have been included in the Rinnai coaxial vertical flue kit. Elbow straps are also available as a separate
component to prevent excess weight on the flue elbow (if used).
Flue terminal locations
Flue terminals must be compliant with the flue terminal locations shown in AS/NZS 5601.1.
The flue cannot terminate under a floor or in a roof space.
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/NS 5601.1
Shared flues
Gas appliances must not be connected to a chimney or flue serving a separate flue burning
appliance.
