TV installation above a replace
If installing a flat screen TV above a fire, the main issue is heat. Heat from the
fire, and heat from the flueing components that could be installed behind the TV
especially if recessed).
The Rinnai Neo gas fires have
a powerful fan that distributes
warm air from 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 general rule for television
installations is that the
bottom of the television
recess should be at least 400-
450 mm above the fire.
For a TV mounted directly
above a fire, the mantel must
be at least the depth of the
TV to deflect heat away from
the appliance.
Always check with the TV
manufacturer
Some television warranty
conditions state that a TV
is not to be installed above
a fireplacealways check
with the TV manufacturer
beforehand.
Rinnai does not accept any
responsibility for damage to
a TV resulting from the use of
this information.

thickness of the external cladding as the zero
clearance box MUST BE installed flush with the
cladding surface to ensure alignment of the
flue.

12 | Neo installation guide: 11906-H 08-15
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.
The connection is either direct wired* or
connected to a power point within the cavity.
This must be connected to a dedicated 240 V,
10 A earthed power point. The electric isolation
switch must be accessible after the appliance
has been installed.
The heater must not be located immediately
below a socket outlet (potential fire hazard).
The power cord is not fire rated and should not
come into contact with the unit. If the power
cord is damaged, it must be replaced by a
licensed tradesperson. This must be a genuine
replacement part available from Rinnai—part
number 6765B.
* Consult a qualified electrician if direct wiring is required as it must comply with AS/NZS 5601 and AS/NZS 3000 and other
relevant local regulations

Neo installation guide: 11906-H 08-15 | 13
Gas supply
Gas pipe sizing must consider the gas input to this appliance as well as all other gas
appliances in the premises. The gas meter and regulator must be specified for the total
gas rate. An approved sizing chart such as the one in AS/NZS 5601.1 should be used.

Flueing guidelines
Minimum flue length - 3.6 m
This is required to ensure adequate draw and to prevent spill-back of combustion products,
which can cause the safety sensors to shut down the fire. The minimum flue length before any
bend or offset is 1.2 m (or one length of flue). The minimum flue length is 3.6 m or three lengths
of flue.
Maximum flue length - 8 m
Rinnai recommends a maximum flue length of 8 m with a maximum of two 45 ° bends.
Difference in flue lengths
For our inbuilt range our flue lengths are all 1.2 m. For our freestanding flues, those that are
powder coated (galaxy black and brushed stainless steel), flue lengths are 1 m. Any easy way to
remember is unpainted 1.2 m, and painted 1 m.
Inner flue: Clearance to combustibles
Clearance from the inner flue to a combustible material must be greater than 25 mm.
Flue cowl clearance
To ensure products of combustion are cleared, adequate clearance for 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 terminal locations
Must be compliant with ‘Clearances Required for Flue Terminals’ from AS/NZS 5601.1. The flue is
not to terminate under floors or in a roof space.
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.
Flashings to to the top of the chimney structure do not form part of the flue kit and
must be specified.

16 | Neo installation guide: 11906-H 08-15
Masonry ue installations
There are two types of masonry flue installations; open chimney and lined chimney. An open
chimney uses the natural draft properties of a sound chimney, an approved chimney plate and
cowl to provide flueing for the heater. A lined chimney installation is used when the existing
chimney condition is inadequate for an open chimney installation and uses a Rinnai flexiliner flue
to provide flueing for the heater.
Check dimensions of opening
Ensure opening is within the range provided, and if necessary bring them to the required
dimensions. Also check chimney height as inadequate height can affect product performance.
Some installations may require the chimney height to be extended to reduce down drafts. Also
check there are no obstructions.
Provide a solid, flat, and sealed base, otherwise noise and vibration may result. Sealed means no
holes or openings in the fireplace.
Some criteria for checking chimney soundness
Rinnai strongly recommends the use of a Rinnai flexiliner flue system. Failure to meet this criteria
may result in an unsafe situation. Installation without a flexiliner flue is permissible as long as the
chimney is swept, checked for soundness and ability to achieve a good draw. Some criteria for
checking soundness:
- All loose/broken bricks must be replaced or repaired ensuring the chimney is of sound
construction and does not leak.
- Chimney must be swept clean and be free from soot and creosote that may have built up if
previously used for a solid fuel fire.
- Any damper plate must be fixed in an open position or removed.
- Any underfloor air supply to the fireplace must be completely sealed to prevent secondary
air draw.
