Flue installation - general guidelines
Flue terminal locations
Must be compliant with ‘Clearances Required for Flue Terminals’ from NZS 5261 2003. Flue is
not to terminate under oors or in a roof space.
Minimum and maximum horizontal ue length
Each ueing conguration is subject to ueing restrictions, refer to following pages for further
detail. General points governing ue congurations are:
• minimum vertical ue before any offsets 600 mm
• maximum horizontal length 3.5 m
• for vertical installations greater than 2.3 m ue restrictor is required to be tted
• bends maximum of two
Self-supporting ue
The weight of the ue system should not be supported by the appliance—it should be self-
supporting. Supporting the ue is usually completed during the framing stage with ue
supports or straps within the cavity. Wall straps have been included in the Rinnai Vertical Flue
Kit to assist with this. Elbow straps are also available as a separate component to prevent
excess weight on the ue elbow.
Shared ues
Gas appliances must not be connected to a chimney or ue serving a separate fuel burning
appliance.
