Gas supply

Gas pipe sizing must consider the gas input to this appliance, as well as other gas
appliances in the premises. The gas supply termination is inside the heater, and enters
from the lower left hand side of the appliance.

To ensure correct positioning terminate the gas supply so it is 175 mm
in from the front face of the enclosure opening.

Purging the gas supply

Foreign materials and debris such as swarf, filings etc. must be purged
from the gas supply. Failure to do so may cause damage to the control
valve causing it to malfunction.

Rinnai recommend the heater be plugged into a 230 V,
10 A earthed power point. The power point must not
be above the heater. Alternatively the appliance can
be direct wired if the power supply is to be concealed.
Consult a qualified electrician if direct wiring is required
as it must comply with AS/NZS 5601.1 and AS/NZS 3000
and other relevant local regulations.

Wall penetration

Direct flue wall penetration requirements

Use the guide pictured to mark the penetration points for the gas supply and flue 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 flue transition only needs to be made for direct flue installations, where the
terminal is directly to the rear of the appliance. If no flue pipe penetration is required the markings are
still useful for indicating the correct position of the flue transition within the enclosure for other flue
applications.

For weatherboard walls, drill through the centre of the weatherboard from the outside, then drill from
the inside through the plaster board.

The main points governing location are flueing and warm air distribution. The Rinnai Evolve has an
integrated zero clearance box that isolates the appliance from combustible materials. This means it can
be installed directly into a decorative fireplace constructed from materials such as wood or plaster.

The heater must be positioned within the enclosure on a flat level surface that allows free movement of
the appliance. The joists used to support the appliance off the ground must be capable of supporting a
minimum of 1.5 times the weight of the appliance. Wheels located at the rear of the heater allows the
unit to slide in and out of the enclosure for installation and maintenance.

Please note

Depending on the type of flue being installed additional nogs may be required so the wall straps in each
flue kit can be securely attached. The additional bracing of the frame is normally completed by the
gasfitter.

Clearances from combustibles

The clearances listed below, measured from the edge of the glass, are
minimum clearances unless otherwise stated.

While the heater is operating

The appliance must not be
installed where curtains or
other combustible materials
could come into contact with
the heater.

The 1000 mm clearance
above is the clearance to the
ceiling.

Mantels and surrounds

Combustible mantels and
surrounds require clearance
from the fire to minimise
fire danger. Mantels
and surrounds, made of
combustible materials such as
wood, are allowed providing
they are outside the minimum
clearances shown.

Hearths

A hearth is not necessary but
can be used for decorative
purposes or protection of
sensitive flooring. A hearth
must not obscure the front of
the fire.

Floor protection

Heat emanating from this
fire may over time affect
the appearance of some
materials used for flooring,
such as, carpet, vinyl, cork or
timber. This may be amplified
if the air contains cooking
vapours or cigarette smoke.
To avoid this occurring, it is
recommended that a mat
be placed in front of this
appliance.

Note: Measurements are taken from the edge of the glass.
The 400 mm side clearance includes side walls.

TV installation

The Evolve has a fan that distributes warm air from the top of the appliance
out into the room. As warm air is dispersed outwards, as opposed to directly
upwards, installation of a TV may be an option.

The diagram shows
recommended clearances
when installing a TV directly
above the Evolve, or into a
recess. All dimensions are in
millimetres.

400 mm dimension

The 400 mm dimension
is the minimum clearance
required to to a mantel. The
image adjacent shows the
dimension from the edge
of the frame, in the case
of the Evolve the 400 mm
dimension can be taken from
the edge of the glass.

For a TV mounted directly
above the unit, the mantel
must be at least the depth of
the TV to deflect heat away.

Always check with the TV
manufacturer

It is up to the owner to check
the TV installation with the TV
manufacturer—some have
warranty conditions that state
a TV is not to be installed
above a fireplace.

Rinnai does not accept any
responsibility for damage to
a TV resulting from the use of
this information.

- Direct B flue (R2732), or

- Direct flue (ASPDFK)

Evolve flue components

- Direct flue (ASPDFK)

* Adaption flue kit: Arriva use ASPKIT03, Evolve use EVOKIT03

Maximum flue length - 8.5 m Maximum number of bends - three One 90 bend = 1 m

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 ASPKIT03/EVOKIT03 is counted as one 90 ° bend.

Direct and direct extended flueing

Direct through-the-wall flueing for walls up
to 385 mm thick. Flue can be extended if the
wall thickness is greater than 385 mm by using
the ASPDFK flue kit and additional lengths of
ESPIPE900.

In-wall vertical flueing

The vertical in-wall flue installation is installed
against an internal wall within a false fireplace
or other suitable cavity, and is run vertically
upwards to a termination point.

Evolve Installation Guide: 12471-C 03-15 | 15

Connect ue system

Consult the Rinnai Arriva and Evolve flue installation guide supplied with the Arriva/
Evolve flue kits for detailed flue installation instructions. For connection of the flue to the
heater refer information below.

Removing the pipe clamp, extension tube and exhaust pipe

Before installing the heater into the enclosure the pipe clamp, telescopic extension tube, and exhaust
pipe need to be removed so there is room to connect the flue system.

1. Undo the pipe clamp and remove the telescopic extension tube from the exhaust pipe.

2. Secure the telescopic extension tube to the flue system with the exhaust pipe lock.

3. Attach the air hose to the flue transition and secure with the cable tie provided.

Please note that in the adjacent image in step 4 the air hose is already connected to the flue. It is much
easier to connect the air hose to the unit than to connect the air hose to the flue once the heater
is in place. Ensure the air intake hose of the heater is properly secured to the air connection on the
flue system using the cable tie provided, and that the rubber seal is placed on the unused air intake
connection.

Flue slide stopper

Flue transition (ASPDFK, EVOKIT03)

The flue transition provides a connection between the flue system and the heater’s flue spigot and air
intake. For all flueing installations, except horizontal direct flueing, the flue transition is counted as a
90 ° bend. The flue transition requires a 5 mm clearance from combustibles. This clearance is provided
automatically when the supplied standoff brackets are used. All other flue components, except the
elbow section of the EVOKIT03, are designed for zero clearance and can be placed hard against timber
or plasterboard.

The exhaust pipe lock is provided with the ASPDFK and EVOKIT03 flue kits

Install heater into enclosure

1. Carefully move the heater into the enclosure, guiding the piping, flexible gas connection, and
telescopic extension tube into the access openings and through the appliance. Ensure that the air
hose is not in a position where it could get caught or crushed by the unit.

2. Once the engine is in place reconnect the flue exhaust to the telescopic extension tube and secure
together with the pipe clamp.

3. Secure the heater flange in place using 11 screws (seismic constraint).

4. Complete gas, air hose, and flue connection. If vertically flueing ensure condensate tube, provided
with the EVOKIT03 flue kit, is attached to the condensate pipe on the heater—refer images below.

Please note: The unit is supplied with the heater condensate already connected.

Removing and replacing the glass panel

Before the burn media can be installed into the combustion chamber, the glass panel needs to be
removed. Remove the four retaining screws—two at the top and two at the bottom. When replacing
tighten all four screws and then back off by quarter of a turn. If the glass panel is screwed too tight, the
panel will bow and the spring release mechanism won’t work properly.

The glass panel needs to be replaced after installing the burn media and before commissioning.

Install burn media - log set

It is important to place the pieces in the correct position. Incorrect placement can create
carbon build-up and affect performance. Malfunctioning due to improper log/granule
placement is not covered by warranty. The unit must never be used with broken logs or other
burn media (except those specifically designed for the Evolve).

The glass retainer will need to be removed before installing the log set and
granules. Use extreme care when handling the log pieces, they are made from a
fragile material and will damage easily.

Use these instructions in conjunction with the burn media guide sheet,
which is attached to the engine. Experience has shown that the majority of
performance problems has been caused by the burn media being installed
incorrectly.

• Evolve 950: Two granule packs

• Evolve 1250: Three granule packs

Adding the granules

The granules as well as being added to create a more realistic log flame affect (by diffusing the gas flames
through the burner ports) also assist in soot prevention and are CRITICAL to the performance of the
heater. Never pour the granules directly from the pack as dust particles from the plastic bag may block
the ports.

DO NOT place the granules near the flame rods or the pilot (areas highlighted in the images below) as
this will cause a blockage and the unit will not start.

Place the granules evenly (do not stack) around the logs in the front part of the burner and on the
middle section of the burner (in the gaps between the logs)—refer fully assembled image.

Install burn media - stones

The glass retainer will need to be removed before installing the stone set and
granules. Use extreme care when handling the stones, they are made from a fragile
material and will damage easily.

Use these instructions in conjunction with the burn media guide sheet,
which is attached to the engine. Experience has shown that the majority of
performance problems has been caused by the burn media being installed
incorrectly.

It is important to place the pieces in the correct position. Incorrect placement can
create carbon build-up and affect performance. Malfunctioning due to improper
stone/granule placement is not covered by warranty. The unit must never be used with
broken stones or other burn media (except those specifically designed for the Evolve).

Before commencing installation ensure you have the correct stone set. The Evolve
950 stone set contains 30 stones, the Evolve 1250 stone set contains 40 stones. The
installation between the two models varies slightly.

Commissioning

The commissioning sheet is located in a plastic
pouch inside the unit on the right hand side.

For all Evolve flueing EXCEPT direct flueing,
the appliance must be down rated as per the
instructions on the commissioning sheet.

Follow the commissioning instructions to
complete the gas pressure adjustments. When
commissioning is complete check for full and
correct operation of the appliance, and return the
commissioning sheet to its plastic pouch.

The gas pressures of the appliance are factory preset for direct flue installations (most
common type of installation) and will normally not require adjustment. The combustion
chamber glass must be on when checking the operating pressures.

Install the inner and outer frames

Installing the outer frame

1. Remove, but don’t discard, the two black screws installed in the lower bracket of the heater engine.

2. Position the outer frame close to the heater engine and connect the RJ45 plug into the socket on
the inside top left of the heater. This connects the push button control panel via a communications
cable to the engine control box.

3. Mount the outer frame to the heater by hooking the top over the two tabs on the top lip of the
engine body, then push in until the frame sits flush with the wall. Secure with the two black retaining
screws removed in step 1.

Installing the optional mesh guard

The optional mesh guard, if purchased, needs to be installed before the inner frame as the inner frame
holds it in place. Hook the mesh guard over the two top mounting tabs on the engine front and rotate
towards the engine body.

Installing the inner frame

1. Hook the tabs of the inner frame to the top lip of the combustion chamber glass.

2. Rotate the bottom of the inner frame in towards the engine body allowing the magnets to secure
the inner frame to the engine.

Test operation and lighting sequence

It may take approximately two hours of operation for the burn media to achieve their full
flame pattern and glow. During the initial burning in period, some smoke and smell may
be experienced. The appliance should run on the high setting in a well ventilated room
until these dissipate. It is important to check the flame pattern during this time.

Abnormal flame pattern

Abnormal flame performance and/or pattern can
indicate a problem with your fire, such as blocked
gas injectors, or that the burn media has shifted.
There are some warning signs that could indicate
a problem.

- Unusual smell from the appliance

- Continued difficulty or delay in establishing a
flame

- Flame appears either very short or very long

- Flame only burns part way across the burner

- Severe soot building up on the inside of the
glass door

Important

It is the responsibility of the installer to check that
under normal conditions of the appliance, all flue
gases are exhausted to the outside atmosphere,
and that there is no spillage of combustion gases
into the room.

If the appliance cannot be made to perform
correctly please contact Rinnai.
