Masonry Installations - Rinnai Neo RIB2311N Installation Manual

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.

Install the heater into the
fireplace
Apply the supplied
foam seal strip
to the rear of the
Minimum
heater. The strip is
200 mm
intended to form
a seal between
the heater and the fireplace. If an
adequate seal cannot be formed
Minimum
with this strip another means
3.6 m
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
Minimum
50 mm
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.
