34 | Linear installation guide 13563-B 02-19
General ueing guidelines
Every gas re requires a ue system that will draw effectively and clear ue 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 ue.
Some guidelines to assist with ue design are detailed below. These must be read and modied as
necessary depending on the installation.
The Linear must be installed with an approved ue system, approved components are shown in
this guide.
Flue clearances to combustibles
The ue transition (refer image) provides
the connection between the ue and the
Linear. This requires a 5 mm clearance from
combustibles. The clearance is automatically
provided with the wall straps are used.
All other ue 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 ue kits, these must be specied.
Flue support
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 are included with Rinnai vertical ue components.
Flue terminal locations
Flue terminals must be compliant with the ue terminal locations shown in AS/NZS 5601.1. The ue
cannot terminate under a oor or in a roof space.
Shared ues
Gas appliances must not be connected to a chimney or ue serving a separate ue burning
appliance.
Flue must be secure
To prevent the ue from moving or coming apart the:
• Joints between the ue 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 ue kit.
Connecting the ue 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 ue 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 difcult. DO NOT use petroleum based lubricants as these will cause deterioration of the
o-ring seals.
