Coaxial Flueing For Internal Models - Rinnai REU-VR3237WG Operation & Installation Manual

GENERAL INSTALLATION INSTRUCTIONS

COAXIAL FLUEING FOR INTERNAL MODELS

Rinnai internal models described in this manual must use the coaxial Rinnai FF flue components. The
use of non Rinnai FF flue components may result in a dangerous situation and violates regulations.
The FF flue system must be installed in accordance with the 'FF Flue Installation Manual' which is
provided with the FF 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
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
installation methods
These are:
(1.) Direct Horizontal
(2.) Extended Horizontal
(3.) Vertical
(4.) Combination Vertical /
Horizontal
Multiple Terminal Installations
The terminal clearances stated in
AS5601 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.
