Clearances
The clearances listed below are minimum clearances unless otherwise stated.
Clearances around the heater
The appliance must not be
installed where curtains or other
combustible materials (coffee
tables, couches etc.) could come
into contact with the heater. In
some cases curtains may need
restraining.
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 the
appliance.
Mantels and surrounds
Mantels and surrounds are allowed
providing they conform to the
minimum clearances shown. These
clearances are important as they:
- allow heat to escape in the
event of a power failure during
operation
- allow optimum performance of
the heater (room air return)
- allow access to the side mesh
filters
Mantel clearance calculation
example
At a 75 mm vertical clearance, the
maximum mantel depth is 25 mm.
For every 25 mm of added mantel
depth, there must be an additional
25 mm of vertical clearance. For
example a mantel depth of
100 mm requires a vertical
clearance of 150 mm.

Location
The main points governing location are flueing and warm air distribution. The Rinnai
Arriva has a cool outer casing, it can be installed into an existing masonry, or decorative
fireplace.
Enclosure dimensions
The heater must be positioned on
a flat level surface that allows free
movement of the appliance. A pair
of wheels located at the rear of
the heater allows the unit to slide
in and out of the enclosure for
commissioning and maintenance.
In a masonry fireplace use a slurry
of sand and cement to level the
base as required.
In a decorative fireplace, when
the appliance is elevated from the
ground, construct a base using
a board with supporting joists as
pictured.

Gas connection
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 rear right hand side of the appliance.
To ensure correct positioning
terminate the gas supply so it is
80 mm in from the front face of the
enclosure opening.
Purging 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.
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 to be terminated
directly to the rear of the
appliance.

Flueing options
Flueing notes
For all installations an Arriva flue system
MUST BE used. Detailed flue instructions
are provided with Arriva flue kits.
Termination point
Flue is not to terminate under floors or in
a roof space.
Condensate
A condensate trap is required for ALL
vertical flue installations to ensure
condensate generated during combustion
is trapped and prevented from entering
the chamber of the heater.
For horizontal, and down and out
installations, there must be a continuous
fall of at least 2°. This equates to
approximately 20 mm per metre to the
termination point to drain the condensate.
For direct flueing, direct flue kits A and B
have an inbuilt 2° fall.
Masonry
The Arriva must not be flued into natural
draft cavities.

bend would be the two 45°bends
(ESBEND).

Down rating the appliance
For all Arriva flueing EXCEPT direct
flueing, the appliance must be down
rated (ensures optimum performance
of the fan) as per the instructions on the
commissioning sheet.
Maximum flue length and number of
bends
• Max. flue length - 8.5 m
• Max. number of bends - three
One 90°bend equals 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 flue transition for all
flueing installations, excluding direct
horizontal flueing, is counted a 90°bend.

Flueing guidelines
It is the responsibility of the
installer to ensure that the
appliance is provided with an
effective flue. Some guidelines
to assist with flue design are
listed below. These must be
read and modified as necessary
with reference to the particular
installation.
The Rinnai Arriva must be
installed with an approved
Rinnai flue system. Approved
flue components for this
appliance are detailed in this
guide.
Clearance to combustibles
• Flue transition (p. 12) - 5 mm
• Elbow component of
adaption flue kit (ASPKIT03)
- 25 mm
All other Arriva flue
components have zero
clearance.
Flashings
Flashings to top of chimney
structure do not form part
of the flue kit and must be
specified.
Flue support
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.
Vertical terminations: 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. Lesser clearances
may provide perfectly adequate
flue systems depending on
the installation. Minimum
clearances are shown in
AS/NZS 5601.1.
Shared flues
Gas appliances must not be
connected to a chimney or flue
serving a separate fuel burning
appliance.
Every gas fireplace requires a flue system that will draw effectively and clear flue products
safely under all potential wind and climatic conditions.
Minimum clearance
500 mm to nearest
part of roof
