General Flueing Guidelines - Rinnai Linear Series Installation Manual

General flueing guidelines

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 Linear must be installed with an approved flue system, approved components are shown in
this guide.
Flue clearances to combustibles
The flue transition (refer image) provides
the connection between the flue and the
Linear. This requires a 5 mm clearance from
combustibles. The clearance is automatically
provided with the wall straps are used.
All other flue components, except the elbow
section of the EVOKIT03, which requires
a 25 mm clearance, are designed for zero
clearance and can be placed against timber or
plasterboard.
Flashings
Flashings are not included with the flue kits, these 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. Wall straps are included with Rinnai vertical flue components.
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.
Shared flues
Gas appliances must not be connected to a chimney or flue serving a separate flue burning
appliance.
Flue must be secure
To prevent the flue from moving or coming apart the:
Joints between the flue components MUST be secured by screws (easier to undo if necessary)
•
through the outer pipes.
Flue components MUST BE secured to the wall using the wall straps provided in each flue kit.
•
Connecting the flue components
The inner pipe joints are sealed with an o-ring seal lubricant. A small plastic tub of silicone grease
is provided with the main flue kits. Use this silicone grease to lubricate the o-rings on the inner
pipes prior to assembly. This is important as the o-rings can dry out and break, and replacing
o-rings is difficult. DO NOT use petroleum based lubricants as these will cause deterioration of the
o-ring seals.
