Every gas re requires a ue system that will draw e󰀨ectively and clear ue products safely
under all wind and climatic conditions. It is up to the installer to ensure the appliance is provided
with an e󰀨ective ue.
Down rating the re
For all ueing EXCEPT direct ueing, the re must be down rated (ensures optimum
performance of the fan) as per the commissioning instructions.

About this guide
This guide is to outline the most common types of ue installations and to provide an overview
of how to assemble the various ue components. If you have an installation that varies from this
guide, please contact Rinnai.
Flue installation di󰀨erences between the Arriva and Evolve
• Direct ue kits di󰀨er
Due to the size of the Evolve unit and the cavity dimensions, the only direct ue kit available
for the Evolve is the ASPDFK. The direct mushroom ue kits that can be used for the Arriva are
not suitable as the telescopic exhaust section of the Evolve is not long enough to connect to
the ue transition of the mushroom ues.
EVOLVE MODELS ASPDFK direct ue kit Mushroom direct ue kit
• Adaption ue kits di󰀨er
- Arriva uses the ASPKIT03, refer p.8
- Evolve uses the EVOKIT03, refer p.8
• How condensate is handled di󰀨ers
For the Arriva a condensate drain kit needs to be installed, refer p.24. For the Evolve the
condensate drain tube is connected directly to the condensate pipe on the heater, refer
appendix 1 on p.25.

Flueing options
For lowest cost, optimal performance, ease of installation and servicing, Rinnai
recommend direct ued installations are considered before all other options.
Maximum ue
length and
number of bends
Maximum ue length = 8.5 m
Maximum number of bends = three
For every 90° bend, the overall length must be reduced by 1 m. For example, if an installation has
three 90° bends, the maximum flue length can be 5.5 m. The elbow component of the adaption flue
kits is counted as a 90° bend.
Adaption ue kits Arriva: use ASPKIT03
Evolve: use EVOKIT03
Direct and direct extended ueing
Direct through the wall ueing for walls up to 385 mm
thick. Flue can be extended if the wall thickness is
greater than 385 mm by using the ASPDFK ue kit and
additional lengths of ESPIPE900.

Sideways ueing
The sideways ue installation can run along the left or
right hand side of an internal wall behind the re. When
considering the location of the re, ensure the ue path is
free from obstructions such as noggins, wiring, joists etc.

For the small number of instances where the re cannot
be directly ued or ued via an internal wall. In some
cases a large portion of the ue may be visible from the
outside.
Down and out ueing
This ue option allows for the adaption ue kit to face
downwards and for the ue to run vertically through a
hole in the oor, and then terminate horizontally outside,
ue termination must be 300 mm above ground level.

General ueing guidelines
Flue clearances to
combustibles
Due to the heat from the ue components, maintain a 25 mm
clearance to combustibles for the rst 500 mm of ue.
Flashings Flashings are not included with the ue kits, these must be
specied.
Flue support The weight of the ue system must not be supported by the
appliance, it must be self-supporting. Supporting the ue is usually
completed during the framing stage with ue supports or straps
within the cavity. Wall straps are included with most Rinnai ue
components.
Securing the ue To prevent the ue from moving or coming apart:
• Joints between the ue components MUST BE secured by
short1 screws (max. length 6 mm) through the outer pipes
(easier to undo if necessary).
• Flue components must be secured to the wall using the ue
straps provided in each ue kit, refer image above.
Lubricate o-ring seals
before connecting
The inner pipe joints are sealed with an o-ring seal lubricant. A small
plastic tub of silicone grease is provided with the main ue kits. Use
this silicone grease to lubricate the o-rings on the inner pipes prior
to assembly. This is important as o-rings can dry out and break, and
replacing o-rings is di󰀩cult.
Do not use petroleum based lubricants as these will cause
deterioration of the o-ring seals.
Flue sections located
outside
Sections of the ue located outside require the following:
• Only use PVC cement between the joints of the outer PVC pipes
to secure and seal the joints against ingress of dust and water.
• Only use non-acidic silicone sealant between the joints of the
outer PVC pipe and any mating aluminium components to seal
the joints against ingress of dust and water. Silicone containing
acetic acid or other acids as the curing agent may cause the
aluminium to corrode.
Shared ues Gas appliances must not be connected to a chimney or ue serving
a separate ue burning appliance.
Condensate The Arriva and Evolve will produce ue condensate when running.
The amount will vary depending on climatic conditions and ue
conguration. Condensate is mildly acidic and can damage
decorative nishes, prized petunias, concrete, and other building
materials. Please consider the customer as to how the condensate
will drain and what it may drain into.
1 Screws must not touch the inner pipe—could cause a transfer of heat to the plastic outer and potentially
melt the plastic.

2° fall to the horizontal ue
terminal
There must be a continuous fall of at least 2°
to the horizontal wall termination. This is so
any condensate and rain water exits the ue
naturally.
The Arriva Direct A and B ue kits have an
inbuilt 2° fall.

Flue terminal locations Flue terminals must be compliant with the ue terminal locations
shown in AS/NZS 5601.1.
• The ue terminal must be positioned away from any
ammable materials.
• Keep snow and other items, such as outdoor furniture well
clear of the ue terminal at all times.

To ensure products of combustion
are cleared, adequate clearance
from the building is required. The
vertical cowl should have a
500 mm clearance from any part
of the building. This also applies to
steeped and pitched roofs, where
the ue cowl should be 500 mm
clear of the ridge line.
An adequate ow of fresh air must
exist around the ue cowl following
installation.

Direct ue wall penetration requirements
Use the guide pictured to mark the penetration points for the gas supply and ue transition
locations. Consideration must be given to the position of any studs, noggins or other components
of the wall structure on both sides of the wall. Mark these measurements accurately as this is
critical to a successful installation.
The penetration for the ue transition only needs to be made for direct ue installations, where the
terminal is directly to the rear of the appliance. If no ue pipe penetration is required the markings
are still useful for indicating the correct position of the ue transition within the enclosure for other
ue applications.
For weatherboard walls, drill through the centre of the weatherboard from the outside, then drill
from the inside through the plaster board.

For installations where the unit is mounted directly on the inside of an external wall.
This installation requires a 2° fall from the heater connection to the wall terminal to
drain condensate and wind blown rain—the Arriva Direct A and B ue kits have an
inbuilt 2° fall.
Direct ueing using the Direct A and B ue kits - ARRIVA models only
Before starting, create the wall penetration. The minimum diameter required is 80 mm to non-
combustible surfaces such as brick, and 100 mm to combustible surfaces such as plaster.

The ASPDFK is suitable from walls up to 385 mm thick. For the Arriva models it
can be used as an alternative to the Direct A and B ue kits. The ASPDFK can
be cut to length to suit wall thicknesses less than 385 mm. The ASPDFK can
also be used in combination with ESPIPE900 for walls greater than 385 mm,
this is called direct extended ueing.
IMPORTANT
Refer p.20 if cutting to length for important information about cutting the outer and inner pipes.
Direct ueing using the ASPDFK
1. Create the wall penetration. The minimum diameter is 80 mm to non-combustible surfaces
such as brick, and 100 mm to combustible surfaces such as plaster. Allow for a continuous 2°
fall from the re to the wall terminal.
2. Slide the internal wall plate over the terminal end of the ASPDFK pipe until it is nested on the
raised ring of the ue transition.
3. Pass the ASPDFK through the internal wall penetration.
4. Slide the internal wall plate so it is ush with the wall.
5. Create the wall terminal, refer p.21.
6. Move the re into place and connect the re ue pipe to the ue. This is done with the ue slide
stopper provided with the ue kit.

Total ue length can be 7.5 m—the elbow component of the ASPKIT03/EVOKIT03 is counted as
a 90° bend. If bends need to be included to o󰀨set a stud, noggin etc., the ue length can be up to
5.5 m and contain two 90° bends (two ESBEND kits).
Steps for creating vertical in-wall ueing
Lubricate all inner pipe o-rings with the silicone grease provided.
1. Join the ue transition and condensate together ensuring the arrow points upwards.
2. Fit lengths of ESPIPE900 as required.
3. Determine the location of the roof or ceiling penetration point. To avoid obstructions an o󰀨set
can be created using the ESBEND kit.
4. Create a vertical roof terminal.
5. Secure joints between ue components through the outer pipes with screws and secure the
entire ue system using the wall straps supplied.
6. Connect the condensate tube to the heater once it has been installed. Connection points will
di󰀨er between the Arriva and the Evolve. For the Arriva refer to p.24. For the Evolve refer p.25.
DO NOT remove cap
Remember to consider how the wall straps will be secured to the frame—additional packing will be
required depending on where the wall straps are positioned.
IMPORTANT
Vertical in-wall ueing
The vertical in-wall vertical ue installation is installed against an internal wall
within a false replace or other suitable cavity, and is run vertically upwards to a
termination point. When considering the location of the re ensure the ue path in
the roof space is free from obstructions such as studs, wiring, joists etc.

Sideways ueing
The sideways ue installation can be run along the left or right hand side of an
internal wall behind the heater. When considering the location of the heater ensure
that the ue path is free from obstructions such as studs, noggins, wiring, joists etc.
Flue length
Total ue length can be 7.5 m—the elbow component of the ASPKIT03/EVOKIT03 is counted as
a 90° bend. If bends need to be included to o󰀨set a stud, noggin etc., the ue length can be up to
5.5 m and contain two 90° bends (two ESBEND kits).
Steps for creating sideways ueing
1. Lubricate all inner pipe o-rings with the silicone grease provided.
2. Join the ue transition and condensate together ensuring the condensate outlet points
upwards. Even though the condensate is not actually connected in this ue arrangement, the
condensate component serves as a transition piece between the transition casting and the
ESPIPE900. The transition component must not be connected directly to the ESPIPE900,
which is plastic, due to the heat of the ue gases.
3. Fit lengths of ESPIPE900 as required. Allow for a 2° continuous fall from the heater connection
point to the wall terminal to drain condensate.
4. Create the wall penetration. The minimum diameter is 80 mm to non-combustible surfaces
such as brick, and 100 mm to combustible surfaces such as plaster. Allow for a continuous 2°
fall from the re to the wall terminal.
5. Create the wall terminal, refer p. 21.
6. Secure joints between ue components through the outer pipes with screws and secure the
entire ue system using the wall straps supplied.
Remember to consider how the wall straps will be secured to the frame—additional packing will be
required depending on where the wall straps are positioned.

Through-wall vertical ueing
These types of installations are rare, but have been used on the odd occasion where
traditional ueing is not possible. As a large portion of the ue will be visible—check
with the homeowner that this is okay. In this example the ue length can be up to
7.5 m long and contain one 90° bend.
Condensate trap
The supplied condensate tube (750 mm) will not be long enough for this type of installation,
a separate tube will need to be used. This needs to be connected back through to the heater
(separate hole required), which needs to be weathertight. Another option is to drain the condensate
to a waste drain / gully trap through a PVC line. For more information please contact Rinnai.
Steps for creating horizontal through-wall ueing
1. Create the wall penetration. The minimum diameter is 80 mm to non-combustible surfaces
such as brick, and 100 mm to combustible surfaces such as plaster. Allow for a 2° fall back to
the heater.
2. Create the 90° bend using the ESBEND kit.
3. Join the condensate trap to the 90° bend.
4. Fit lengths of ESPIPE900 as required.
5. Create a vertical roof terminal.
6. Secure joints between ue components through the outer pipes with screws.
7. Connect the condensate tube to the heater. You will need to drill a separate hole to run the
condensate tube back to the heater. Connection points will di󰀨er between the Arriva and the
Evolve. For the Arriva refer to p.22 in this guide, for the Evolve refer to p.25.

Flue components:
• Direct ue kit (ASPDFK)
• 45° bends (ESBEND)
• Condensate trap (ESCONDK)
• Flue pipe (ESPIPE900)
• Roof cowl (ESROOFCOWL)
Flue components required for through-wall ueing
As there is a vertical component in the installation, condensate needs to be drained back
towards the re, this requires the ASPDFK component to be angled 2° back to the unit.

Down-and-out ueing
The down-and-out ue option allows for the adaption ue kit to face downwards
and for the ue to run vertically through a hole in the oor, and then horizontally
to a suitable location outside. When considering the location of the heater
due care must be taken to ensure that the ue path under the oor is free of
obstructions such as studs, noggins, joists, braces, wiring etc.

Steps for creating down and out ueing
1. Lubricate all inner pipe o-rings with the silicone grease provided.
2. Join the ue transition and condensate together ensuring the condensate arrow points
downwards. Even though the condensate is not actually connected in this ue arrangement,
the condensate component serves as a transition piece between the transition casting and the
ESPIPE900. The transition component must not be connected directly to the ESPIPE900 due
to heat of the ue gases.
3. Fit lengths of ESPIPE900 as required.
4. Create the oor penetration, ensure the hole edges are smooth. The minimum diameter is
80 mm to non-combustible surfaces such as brick, and 100 mm to combustible surfaces such
as plaster.
5. Pass the ESPIPE900 through the wall plate and through the oor penetration and secure wall
plate in place to seal the oor.
6. Prepare the horizontal section of the ue system under the oor by connecting ESPIPE900,
ESBEND and subsequent ESPIPE900 lengths as required. Allow for a 2° continuous fall from
the rst section of horizontal pipe to the wall penetration to drain condensate.
7. Create the wall terminal, refer p.21.
8. Secure joints between ue components through the outer pipes with screws and secure the
entire ue system using the wall straps supplied.

Cutting components to achieve the desired ue length
1. Measure and mark o󰀨 the outer pipe at the desired length.
2. Cut the outer pipe to the required length. Take care not to cut the inner pipe.
3. From the new end of the outer pipe measure and mark o󰀨 an additional 12 mm on the inner
pipe. Cut the inner pipe at this mark. Take care to keep the cut parallel to the outer pipe.
The additional 12 mm shown in the diagram above is required to allow the component to be joined
to another part.
• The minimum length of the ASPDFK when measured from the back plate of the
transition casting MUST NOT be less than 300 mm when joining to other components.
• Ensure all burrs and swarf are removed from any cut ends.
• ESPIPE900 can be cut to size at the non-socketed end
