CAUTIONS: Indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury or damage to the appliance. It may also be used to alert against unsafe practices.
REGULATORY INFORMATION
Your Rinnai gas continuous ow water heater ue has been certied by the Australian Gas Association. The A.G.A. Certication Number is shown on the data plate.
These ueing components MUST be installed in accordance with:
Current AS/NZS 3500 and AS/NZS 5601
The installation MUST comply with all relevant instructions supplied by Rinnai.
Service and removal MUST be carried out by an authorised person.
Local regulations and municipal building codes including local OH&S requirements
Flue components MUST be installed correctly by an appropriately licensed tradesperson. The installation of gas, water, and electricity must conform to local regulations.
All dimensions referred to in these instructions are in millimetres, unless otherwise specied.
These instructions ONLY apply to the Rinnai FFU water heater coaxial ueing system. This ue system utilises pipe components with a aluminium inner pipe and a white plastic outer pipe.
These instructions DO NOT apply to older Rinnai water heater ueing that has either a stainless steel single skin or stainless steel coaxial construction. If in doubt contact Rinnai.
Before commencing installation, please read the 'Installation Instructions - General', located inside a pouch behind the front cover of all Rinnai water heater models. The Rinnai internal water heater range must only be installed with Rinnai water heater ueing as referred to in these instructions.
Appliances are certied to be installed side by side as shown on page 6. Refer to the operation and installation manual provided with the appliance for clearance details pertaining to single appliance installations.
A Rinnai internal continuous ow water heater tted with an FFU ue system is room sealed as dened in AS/NZS 5601. No ventilation in the space where the water heater is installed is required.
The outer plastic section of the coaxial ue complies with temperature hazard requirements and can be installed with zero clearance to combustible material.
Notice to Victorian Consumers
The appliance and ue components MUST be installed by a person licensed with the Victorian Building Authority. ONLY a licensed person will have insurance protecting their workmanship. So make sure you use a licensed person to install this appliance and ask for your Compliance Certicate.
For further information contact the Victorian Building Authority on 1300 815 127.

CUTTING THE FLUE COMPONENTS
IMPORTANT

x + 10 mm
WARNINGS & IMPORTANT INFORMATION
Using the dimensions shown on page 10, calculate
the required number and type of ue components that are needed to reach from the water heater to the ue
terminal.
When cutting components the outer ue pipe should be cut to the required length plus 37mm and the inner ue
pipe should be cut to the required length plus 47mm, this will ensure that the correct penetration is provided for joining of components.
When inner and outer pipes are re-assembled after cutting the inner pipe should extend 10mm beyond the end of the outer pipe. See Fig. 1.
Cutting ue components can create sharp edges, care must be taken to avoid injury, use a le to remove debris, burrs and sharp edges from cut ends.
Ends that are left unnished can damage the ue seals and result in the ue components no longer being air or weather tight.
The ONLY COMPONENTS that can be cut are as follows: FFPIPE1000, FFROOFCOWL and FFWALLTERM.
Ensure all ends are cut square (the use of a mitre box will ensure a clean square cut).

A container of "O" ring grease is provided. To ease assembly, lubricate the “O” rings of the inner pipes of each ue
component prior to assembly.
Use only a silicone based "O" ring seal lubricant. DO NOT use petroleum based lubricants such as petroleum jelly, as such products may cause deterioration.
APPLIANCE SPIGOT DIMENSIONS & CENTRES
When viewed from the front, the ue spigot is aligned
with the centreline of the appliance.
The wall mounting brackets are adjustable by 50mm, with the minimum setting being 10mm, as such when adjusted the spigot centre relative to the wall mounting surface will also change.
For the minimum and maximum position of the spigot centre relative to the wall mounting surface for each
