Locaon
The main points governing location are ueing 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 replace is not designed
to be built into bookcases.
Standard ued appliances draw the air for combustion from the room itself so there is a need
for xed ventilation. Fixed ventilation must be provided as per NZS 5261.
Clearances
The clearances listed below are minimum clearances unless otherwise stated.

Locaon
Mantels, surrounds, and hearths for inbuilt installaons
A mantel and surround are allowed providing they are outside the minimum clearances shown
on the previous page.
Minimum clearance
The minimum clearance from the top of the appliance is 400 mm. The depth of the mantel/
surround at this minimum clearance must not exceed 150 mm.
Additional mantel/surround depth
For every 50 mm of added mantel depth/surround, there must be an additional 100 mm of
clearance. For example; a 200 mm mantel depth will require a 500 mm clearance from the top
of the appliance.
Hearths
A hearth is not necessary but can be used for decorative purposes or protection of sensitive
ooring if required. It must not obscure the front of the re.
Electrical connecon
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
and 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 re 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 tted 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 re 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.

Locaon
TV installaon above a replace
If installing a at screen TV above the re the main issue is heat. Heat from the re and heat
from the ueing components that sit behind the TV, especially if recessed.
The Neo gas res 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 below outlines recommended minimum clearances when
installing a TV directly above the Neo inbuilt models. All dimensions are in millimetres.

The 400 mm dimension is the
minimum clearance required
to combustibles and to a
mantel.
For a TV mounted directly
above the Neo, the mantel
must be at least the depth
of the TV to deect the heat
away from the appliance.
It is up to the customer to check the TV installation instructions with the TV supplier to verify
clearances. Some TV manufacturers have warranty conditions that state a TV is not to be
installed above a replace.
Rinnai does not accept any responsibility for damage to a TV resulting from the use of this
information.

General ueing informaon
Flashings
Flashings to the top of chimney structure do not form part of the ue kit and must be specied.
Clearance to combusbles
For installations using the Rinnai zero clearance ue components, the minimum clearance from
inner ue to combustible material must be greater than 50 mm. This equates to 25 mm from
the outer ue when using the Rinnai twin-skin ue.
Flue length and number of bends
Minimum ue length
This is required to ensure adequate draw and prevents spill-back of combustion products which
can cause the safety sensors to shut down the unit.
• minimum ue length before any bends or osets = 1.0 m
• minimum vertical ue length = 3.6 m
Maximum ue length and number of bends
Rinnai recommend a maximum ue length of 8 m with a maximum of two 45° bends.
Self-supporng ue
The weight of the ue system should not be supported by the appliance—it
should be self-supporting. Supporting the ue is usually completed during the
framing stage with ue supports or straps within the cavity.
Every gas replace requires a ue system that will draw eectively and clear ue 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 eective ue.
For installations requiring a ue, a Rinnai ue system must be used. The ue system must be
fully assembled and secured in place before the appliance is installed.

General ueing informaon
Shared ues
Gas appliances must not be connected to a chimney or ue serving a separate fuel burning
appliance.
Flue cowl clearance
To ensure products of combustion are cleared, adequate clearance for the building is required
and the below guideline is recommended.
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 below.
Lesser clearances may provide
perfectly adequate ue systems
depending on the installation.
Minimum clearances are shown
in NZS 5261.

Masonry installaons
1. Check dimensions of the opening
Refer 'Enclosure dimensions' and if necessary bring them to the required dimensions.
Check the chimney height as inadequate height can eect product performance. Some
installations may require the chimney height to be extended to reduce down drafts.
2. Check ueway
• Ensure there are no obstructions
• Provide a rm, at and sealed base (sealed means no holes or openings in the replace)
• Ensure adequate support of the appliance (if not properly supported noise and vibration
may result)
3. Install exiliner ue system
To ensure adequate draw for maximum performance of the appliance, Rinnai strongly
recommends the use of a Rinnai exiliner ue system for masonry installations. Failure to meet
this installation criteria may result in an unsafe situation. Performance issues resulting from
inadequate ueing is not covered by the warranty.
Installation without a exiliner is permissible in masonry installations as long as the chimney
has been checked for soundness and ability to achieve a good draw.

4. Installing the heater into the replace
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 replace. If an adequate seal cannot be formed with this strip
another means of sealing must be used (non-combustible insulation) between the replace and
the heater body.
If using a exiliner ue, 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 ue guide rails from the ue 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 ue spigot are correctly aligned.
Carefully move the appliance into the enclosure ensuring the gas supply feeds into the rear
access hole and fasten heater to the replace.

1. Construct frame and install zero clearance box
Refer 'Enclosure dimensions' and construct frame. Assemble and install the RIB2310 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 ush with the cladding surface.
For installations into a mock chimney a Rinnai zero clearance box and zero clearance ue kit is
required to isolate the appliance from combustible materials. Failure to meet this installation
criteria will void any product warranty.

2. Install the ue and complete electrical connecon
The weight of the ue system should not be supported by the appliance—it should be self-
supporting. Supporting the ue is usually completed during the framing stage with ue
supports or straps within the cavity. Flue supports have been included with the ue kit to assist
with this. These are to be riveted to the ue.
Please note, a twin-skin ue requires a 25 mm clearance (from the outer ue) from
combustibles.

Log set installaon
The granule pack and log set, consisting of ve log
pieces, comes packaged inside the appliance, you will
need to remove the glass retainer (four screws) 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 you position the pieces in the order
shown below. Incorrect placement can create carbon build up and eect performance.
Malfunctioning due to improper log placement is not covered under warranty. The unit must
never be used with broken logs and should not be mixed with other burn media (except the
Rinnai Neo granules).
