Location
The main points governing location are flueing and warm air distribution. The heater
must not be installed where curtains or other combustible materials could come into
contact with the appliance. In some cases curtains may need restraining.
The Neo gas fireplace is not designed to be built into bookcases.
Standard flued appliances draw the air for combustion from the room so there is a need
for adequate ventilation. Adequate ventilation must be provided as per AS/NZS 5601.1.
Clearances around the heater
The clearances listed below are minimum clearances unless otherwise stated.

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

Neo installation guide: 11906-F 06-14 | 9
Electrical connection
The Neo is supplied with a power cord (length 1500 mm) and a 3-pin plug. The standard
electrical connection passes through the rear panel, but can also pass through the left or
right hand side of the unit by removing the knockout tab from the bottom edge of the
front panel. If changing the electrical position use the rubber grommet from the rear of
the appliance for cable protection.
Rinnai recommend the heater is plugged into a
dedicated 240 V, 10 A earthed power point. The power
point must not be located above the heater (potential
fire hazard). If the supplied plug and power cord is to be
used with an external power point then the power cord
will need to be fitted with the supplied grommet.
A suitable means of electric isolation must be provided
which is adjacent to the appliance and accessible with
the appliance installed.
The electrical cord is not fire rated and should not come
into contact with the unit. If the supply cord is damaged,
it must be replaced by a licensed tradesperson. This
must be a genuine replacement part available from
Rinnai—part number 6765B.

10 | Neo installation guide: 11906-F 06-14
TV installation above a replace
If installing a flat screen TV above the fire, the main issue is heat. Heat from the fire, and
heat from the flueing components that sit behind the TV—especially if recessed
The Neo gas fires have 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 Neo inbuilt
models. All dimensions are in
millimetres.
400 mm dimension
The 400 mm dimension is the
minimum clearance required to
combustibles to a mantel.
For a TV mounted directly above
the Neo, the mantel must be at
least the depth of the TV to deflect
heat away from the appliance.
Always check with the TV
supplier
It is up to the owner to check
the TV installation with the TV
supplier to verify clearances. Some
TV manufacturers 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.

Flueing guidelines
Inbuilt masonry installations Inbuilt mock chimney installations
Without flexiliner With flexiliner A = Direct flue (straight vertical) B = Offset flue
Freestanding installations
Flueing notes
Every has fireplace requires a flue system that will draw effectively and clear flue products safely under all
potential wind and climatic conditions. It is the responsibility of the installer to ensure that the appliance is
provided with an effective flue. Some guidelines to assist with the flue design are listed below.
Flue cowl
An approved 100 mm cowl must be fitted
to all appliances.
Masonry installations
Rinnai strongly recommends the use of a
Rinnai flexiliner flue system (flexi Ø
100 mm). Failure to meet this criteria
may result in an unsafe situation.
Installation without a flexiliner flue is
permissible as long as the chimney is
sound and able to achieve a good draw.
Mock chimney installations
Natural draft flue.
For installations into a combustible
opening, a Rinnai zero clearance box and
flue kit are mandatory.
Flue dimensions; outer 150 mm, inner
100 mm.
Flue length and number of bends
-Minimum flue length
This is required to ensure adequate
draw and prevent spill-back of
combustion products which can
cause safety sensors to shut down
the unit.
Minimum flue length before and
bends or offsets—1.0 m.
Minimum vertical length—3.6 m.
-Maximum flue length
Rinnai recommend a maximum of
8 m with a maximum of two 45 °
bends.
Clearance to combustibles
There must be a 25 mm clearance from the
inner flue to any combustible surface.
Flashings
Flashings to the top of the chimney
structure do not form part of the flue kit
and must be specified.
Flue cowl clearance
To ensure products of combustion are
cleared, adequate clearance from the
building is required.
The flue cowl should have a 500 mm
clearance from any part of the building.
This also applies to steeped and pitched
roofs, which should be clear of the ridge
line as shown. Lesser clearances may
provide perfectly adequate flue systems
depending on the installation.
Minimum clearances are shown in
AS/NZS 5601.1.
Flue cowl clearance—500 mm clearance from any part of the building
Self-supporting flue
The weight of the flue
system should not
be supported by the
appliance—it should
be self-supporting.
Supporting the flue is
usually completed during
the framing stage with
flue supports or straps
within the cavity.
Shared flues
Gas appliances must not be connected
to a chimney or flue serving a separate
fuel burning appliance.
Flue terminal locations
Must be compliant with the flue
terminal clearances as shown in
AS/NZS 5601.1. Flue is not to terminate
under floors or in a roof space.

14 | Neo installation guide: 11906-F 06-14
Masonry installations
Check dimensions of the
opening
Refer to ‘Enclosure dimensions’
and if necessary bring them to the
required dimensions.
Check the chimney height as
inadequate height can affect
performance. Some installations
may require the chimney height
to be extended to reduce down-
drafts.
Check where the flue is going
- Ensure there are no
obstructions.
- Provide a firm, flat and sealed
base (sealed means no holes
or openings in the fireplace).
- Ensure adequate support of
the appliance—if not properly
supported noise and vibration
may result.
Install flexiliner flue system
To ensure adequate draw for
maximum performance Rinnai
strongly recommends the use
of a Rinnai flexiliner flue system
for masonry installations. Failure
to meet this installation criteria
may result in an unsafe situation.
Performance issues resulting from
inadequate flueing is not covered
by warranty.
Installation without a flexiliner
is permissible in masonry
installations as long as the chimney
has been checked for soundness
and ability to achieve a good draw.
Masonry installation without a
flexiliner flue
Masonry installation with a
flexiliner flue
Install the heater into the
fireplace
Apply the supplied
foam seal strip
to the rear of the
heater. The strip is
intended to form
a seal between
the heater and the fireplace. If an
adequate seal cannot be formed
with this strip another means
of sealing must be used (non-
combustible insulation) between
the fireplace and the heater body.
If using a flexiliner flue, prepare the
heater engine by drilling four x Ø
3.2 mm holes in the pre-pressed
dimples on the top panel of the
heater. Attach the flue guide rails
from the flue kit using the supplied
screws. Align the guide rails with
the guide plate and slide the heater
engine into the enclosure until the
guide plate is fully against the rear
of the front assemblythis will
ensure the heater and flue spigot
are correctly aligned.
Carefully move the appliance into
the enclosure ensuring the gas
supply feeds into the rear access
hole and fasten the heater to the
fireplace.

Mock chimney installations
For installations into a mock chimney a Rinnai zero clearance box and zero clearance flue
kit is required to isolate the appliance from combustible materials. Failure to meet this
installation criteria will void any product warranty.
Construct the frame and install
the zero clearance box
Refer ‘Enclosure dimensions’ and
construct the frame. Assemble
and install the zero clearance
box. Installation needs to be on
a level base. If this is not done
the appliance may twist and
become damaged—this will void
any product warranty. The zero
clearance box is installed flush with
the cladding surface.

Freestanding installations
While the following diagrams depict the Neo Freestanding Console model, the steps to
construct the Neo Freestanding Plinth model are the same.
Attach the flue spigot to the
Neo engine
Using a 3.3 mm drill bit drill
through the four dimples at the
rear of the back panel of the Neo
engine. Attach the flue spigot with
the screws provided.
Assemble, position, and secure
the base assembly to the floor
Assemble the base assembly
provided in the Neo freestander kit
and place on the floor where the
Neo is to be located. Using three
appropriate bolts or screws secure
the base assembly to the floor. This
also acts as a seismic constraint.
Attach the heater to the base
assembly and fit the back panel
Lift the Neo engine into position
over the base assembly and fix into
position using the four M5 x 10
screws supplied.
Remove the three screws from the
base of the unit (do not discard)
and screw the back panel into
position (nine screws in total).
Add the top and side panels
Install the top panel using the
three M5 x 10, and three tapping
screws. Install the side panels
(ensure you push up to minimise

Log set installation
The granule pack and log set, consisting of five log pieces, comes packaged inside the
appliance. The glass retainer will need to be removed before installing the granules and
log set. Use extreme care when handling the log pieces, they are made from a fragile
material and will damage easily.
It is important to position the pieces in the order shown below. Incorrect
placement can create carbon build-up and affect performance. Malfunctioning
due to improper log placement is not covered by warranty.
The unit must never be used with broken logs or other burn media (except the
Neo granules).
1. Check to ensure the ports of the main burner
are clean and clear of any particles and all
packaging.
2. Select the thicker ‘Y’ log and fit into position
by lining up the two pin holes onto the two
pins of the locating bracket that is fixed to the
centre of the main burner.
3. Select the short straight log with the single
locating pin and place onto the metal tabs
at the left and rear of the burner boxwill
touch the burner box walls when correctly
positioned.
4. Select the thinner ‘Y’ log and fit into position
by linking up the two pin holes onto the two
pins of the first two logs. Ensure this log is
seated all the way down until in touches logs 1
and 2.
5. Select the longest log and line up the hole with
the pin of log 1. When correctly located this
log will be touching the burner box walls and
resting on log 1.
6. Locate the final bowed log and line up the hole
with the pin bracket to the right of the burner,
and locate the front of the log onto the stop
bracket. When correctly positioned it will be
touching both brackets, log 4, and the right
burner box wall.

Granule pack installation
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.
NG installations
Place the granules evenly across the burner—use the whole pack.
ULPG installations
Carefully place 30 of the granules as close as possible to the front burner ports as shown on the diagram below.
DO NOT cover any of the front right side ports. It’s important this is done correctly as incorrect placement can
cause high yellow flames (dirty combustion) that may cause sooting.
It is desirable that the flames touch the granules as this diffuses any ‘candling’ effect and enhances the realistic log
burning look of the heater.

Neo installation guide: 11906-F 06-14 | 19
Inner frame and control panel
Before fitting the frame assembly ensure that it is not scratched or damaged. When
placing the assembly down ensure it is placed on its lower edge or flat. If it is placed
on its left or right edge the glass may slide out off the stand-off posts. If this should occur
ensure that the silicon mounts are not dislodged when sliding the glass back into position.
WARNING
Fit the inner frame
The inner frame (packed with the
outer frame) is held in position by
the return tabs on the top edge
and by magnets on the bottom
edge. Fit the inner frame to the
heater engine by locating the
over-folded edge over the two
return tabs, then gently swing
down the bottom edge onto the
magnets.

Test pressures
Check and set the burner
pressures
1. Refer to the data plate located
inside the appliance on the
front left hand side for the
correct gas pressure settings.
2. Using a screw driver loosen
the captive Appliance Test
Point Pressure Screw (ATPP)
and fit the manometer.
3. Remove the dust cap from the
regulator adjusting nut and
screw.
High pressure setting
Turn the appliance on and set
the heater to its highest setting
(refer operation manual). Using a
screw driver hold the low pressure
adjusting screw stationary while
adjusting the high pressure setting
nut with a 10 mm spanner. Turning
the nut clockwise will increase the
outlet pressure while turning the
nut anti-clockwise will decrease
the outlet pressure.
Low pressure setting
1. Disconnect the power to the
Gas Control Valve (GCV) by
separating the connector
for the power supply
(yellow wires). The GCV will
automatically default to low
pressure operation. Using
a 10 mm spanner hold the
high pressure adjusting nut
stationary while adjusting
the low pressure screw with
a screw driver. Turning the
screw clockwise will increase
the outlet pressure while
turning the screw anti-
clockwise will decrease the
outlet pressure.
2. Replace the dust cap to its
original position. It’s important
this is done correctly to ensure
the correct operation of the
GCV.
3. Reconnect the power to
the GCV by rejoining the
connector (yellow wires).
4. After confirming the correct
pressures, turn the appliance
off, remove the manometer,
tighten the ATPP sealing screw
and leak test.
5. Turn the appliance on and off a
few times to check ignition.
6. When you are satisfied that the
heater is working correctly,
reassemble and start the
appliance to check the flame
pattern (refer next page).
