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.
* 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
Using existing externally mounted power points on inbuilt installations
If you already have an existing power
point outside the enclosure, you can
redirect the power cord and plug through
the LHS or RHS of the front panel. With
the frame removed redirect the cord and
plug (with the grommet), underneath the
unit and to the front (left or right).
Remove the pre-punched metal knock-
out located in the lower left or right edge
of the frame. Refit the cord and plug to
the frame, ensuring the grommet is fitted
to the metal knock-out. Excess cord may
be left in the cavity below the unitDO
NOT coil excess cord.
Electrical knock-out position on a Neo frameknock-
out is on both sides of the frame.

Mantels and surrounds - inbuilt models only
Combustible mantels and surrounds require clearance from the unit to minimise
the risk of fire. Mantels and surrounds, made of combustible materials such as
wood, are allowed providing they are outside the minimum clearances shown.
The Neo gas fireplace is not designed to be built into bookcases.

Clearances from combustibles
The clearances listed below, measured from the edge of the inner 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
400 mm side clearance includes side walls.
Floor protection
Heat 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.
Hearths
A hearth is not necessary, but can be used for
decorative purposes or protection of sensitive
flooring. A hearth, if installed, must not
obscure the front of the fire.
TV installation above the fireplace
The Neo 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.
Generally the bottom of the television
recess should be at least 400 mm above
the fire. Please check with the television
supplier to check clearances. Some television
manufacturers have warranty conditions that
state a television is not to be installed above a
fireplace.
For further information refer to p. 14.
