Rinnai Australia 30 Installation Manual
GENERAL INSTALLATION INSTRUCTIONS
CO-AXIAL FLUEING FOR INTERNAL MODELS
Rinnai internal models described in this manual must use the Co-Axial Rinnai FFU flue components.
The use of non Rinnai FFU flue components may result in a dangerous situation and violates
regulations.
The FFU flue system must be installed in accordance with the ‘FFU Flue Installation Manual’ which is
provided with the FFU flue terminal components FFWALLTERM or FFROOFCOWL.
Installations can consist of both
horizontal and vertical runs to a
maximum length of 9 metres and
with a maximum of three 90° bends.
If flue length exceeds 1.5m,
dipswitch 1 of SW1 is to be switched
to the 'OFF' position.
This increases the combustion
speed to overcome the additional
friction loses.
Basic methods of installation
There are four basic flue installation
methods available. These are:
(1.) Direct Horizontal
(2.) Extended Horizontal
(3.) Vertical
(4.) Combination Vertical /
Horizontal
Multiple Terminal Installations
The terminal clearances stated in
AS/NZS 5601 do not apply to the
Rinnai internal continuous flow
water heaters when they are
installed side by side.
AGA certification allows for a
horizontal separation of 160 mm for
roof terminals and 270 mm for wall
terminals.
