1. Direct Flueing With Wall Terminal
1.
The Rinnai Infinity 'Direct Flueing components must be used for this purpose. These consist of a 90º-bend
adaptor, wall terminal and one wall plate. An additional wall plate can be purchased as an optional extra for
Internal Installation.
2.
Dimensions of the REU-V2632FFU/REU-V2632FFUC water heaters for 'direct' flueing are as shown in
(Fig.7)
.
Ensure there is enough space to install the Infinity, flue assembly and pipe work. Also ensure that positioning
of the flue terminal complies with the requirements of AS5601/AG601
Clause 5.13.6.2
/
Fig.5.3 page 10.
Warning:
The flue products can reach temperatures up to 200°C. The flue terminal is to terminate in a
location, not to cause a nuisance. (AS5601/AG601/2002 clause 5.13.3.3).
Installation
1.
Using the dimensions provided in
(Fig.7)
mark the top Water Heater location hole situated in the centre of the
top-mounting bracket and the centre point for the flue terminal hole.
2.
Install the REU V2632 FFU water heater as per the installation instructions located in the pocket on the back
of the front heater cover.
3.
When installing the 90º Bend Adaptor directly backwards from the appliance it is necessary to extend the
mounting brackets of the water heater to the 50mm mark to allow for the radius of the bend. Loosen the
heater-mounting bracket securing screws and adjust the heater away from the wall as far as possible.
4.
Drill a 135mm hole for the flue (Cover the flue spigot to avoid debris entering the appliance flue connection).
NOTE: If the hole is drilled accurately the 90º adaptor bend will cover the hole and an internal wall plate will
not be necessary. Otherwise an extra wall plate can be purchased. (Rinnai Part No. FFWPLATE).
5.
Measure the length of the horizontal terminal and cut to length allowing for the outer section of the flue to
extend 10mm through the wall. (See the section cutting flue components
(Fig.9)
.
6.
From outside the building, fit the external wall plate to the flue terminal and place through the hole in the wall
(Fig. 2).
Connect the terminal onto the 90º adaptor bend. Ensure the wall terminal pushes 'fully home' into the
adaptor. The arrow on the side of the bend will face the in the direction of discharge.
7.
To prevent rain water from entering the flue terminal ensure the required 2
o
fall to outside is achieved
(Fig. 2)
.
8.
On the outer wall, secure the decorative wall plate. Ensure the 2º fall to the flue terminal is achieved.
9.
Seal the flue around the wall plate using silicon sealant.
2. Horizontal Extension Flueing With Wall Terminal
1.
This option
(Fig.2)
can be used when the water heater is mounted against an internal wall and flueing needs to
extend horizontally to exit an external wall. The Rinnai Infinity 'Direct Flueing components' must be used for this
purpose, together with extension pieces & bends as required.
Total flue length can be up to 9 metres long &
a maximum of 3 bends can be used.
2.
Dimensions of water heater with 90° bend adaptor connected are as shown in
(Fig. 2 & 7)
When the flue tracks
horizontally, it should be installed to have a 2° fall towards the wall terminal to prevent condensation running
back into the water heater as shown. Ensure there is enough space to install the Infinity, flue assembly and
plumbing pipe work. Ensure that positioning of the flue terminal complies with the requirements of
AS5601/AG601
Clause 5.13.6.2
/
Fig.5.3 page 10.
Warning:
The flue products can reach temperatures up to 200°C. The flue terminal is to terminate in a
location, not to cause a nuisance. (AS5601/AG601 clause 5.13.3.3).
Installation
1.
Using the dimensions provided in
(Fig. 7)
, Install the REU-V2632FFU/REU-V2632FFUC water heater as per
the installation instructions located in the pocket on the back of the front heater cover.
