2.
Using the dimensions shown in
(Fig. 7)
calculate the required number and combination of extension pieces
and bends to be connected between the Infinity unit and wall terminal. Cut each length as required. (See the
section cutting flue components
(Fig.9).
3.
Connect the 90º bend adaptor onto the heater flue spigot in the direction required. The arrow on the side of
the bend will face the in the direction of flue discharge.
4.
Drill a 135mm hole for the flue terminal (Cover the flue spigot to avoid debris from entering the appliance).
5.
From outside the building, fit the wall plate to the flue terminal and place through the hole in the wall.
6.
From inside the building fit a wall plate (if required) onto the flue.
7.
Repeat steps 4 and 5 for all internal wall penetrations.
8.
Secure the extension pieces between the flue terminal and 90º adaptor bend, ensuring a 2
°
fall to outside.
9.
Ensure the flue is totally supported with the brackets supplied in each length of flue pipe.
10.
Adjust the heater to the required distance from the wall and tighten the hanging bracket securing screws.
11.
Secure the decorative wall plates with the terminal in the sloped down position and secure to inner and outer
walls.
12.
Seal between the flue and the wall plates using silicon sealant.
3. Vertical Straight Flueing With Roof Terminal
1.
This option can be used when the water heater needs to be flued vertically through the roof. The Rinnai Infinity
'Vertical Flueing Components' with extension pieces and condensate trap (if necessary) is used for this
purpose. The 'Vertical Flueing Components' consists of a Flue terminal and vertical adaptor. If the total flue
height is less than 1.5 metres, a condensate trap is not required. For installations over 1.5 metres a
condensate trap is required.
(Fig.3)
Total flue length can be up to 9 metres long and a maximum of 3
bends can be used.
2.
All vertical installations start with the vertical adaptor. This MUST be connected with the larger end (Black
outer seal) facing down on the appliance
3.
Ensure there is enough space to install the Infinity, flue assembly and pipe work. Check the roof space for any
flue obstructions. Also ensure that positioning of the vertical flue terminal complies with the requirements of
AS5601/AG601
Clause 5.13.6.2
/
Fig.5.3.
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.
2.
Fit the vertical adaptor and condensate trap (if required) onto the water heater.
3.
Set plumb bob from the centre of the heater flue outlet to ceiling marking position. Cut 127mm hole in
plasterboard (or suitable 'oval' for pitched roof). Repeat this step for underside of roofing.
4.
Calculate the required number and combination of extension pieces and cut to length as
required (See the
section cutting flue components
(Fig.9)
5.
Install flue and terminal. Flue to terminate at least 500mm from the end of the flue to the nearest part of the
roof. (AS5601/AG601 clause 1 5.13.6.2) see
(Fig.3)
. Seal the roof penetration with an approved flashing.
6.
Install ceiling ring. (Not supplied, if required Rinnai Part No. FFWSEAL).
7.
Ensure the flue is fully supported independently of the appliance, by the use of suitable clips or brackets, as per
AS5601/AG601 clause 5.13.4.2 and 5.13.4.3.
8.
Ensure that the appliance can be removed without causing movement or displacement of the flue, as per
AS5601/AG601 clause 5.13.4.1. This can be achieved if a 100mm distance is kept between the gas and water
isolating valves and the connection points at the water heater
(Fig.5).
9.
Ensure the condensate trap outlet (if fitted) is drained in accordance with the requirements of AS3500.4.2
clause 4.12.
10.
All external outer plastic joints should be glued with approved cement to prevent water entering the flue.
