Rinnai strongly recommends that this appliance be installed with an approved
flue liner system in all installations.
Installation without a flue liner is however permissible into masonry chimneys only after physical inspection
and testing of the chimney to set criteria. Installation of this appliance into a chimney that fails to meet this
criteria will not only void the product warranty, but is highly likely to impede product performance.
The following criteria must be met in all cases:-
Internal Criteria:
• Allow sufficient height above the firebox to enable the debris diverter (See page 8) to be fully operational
°
(ie. open 45
). Failure to do so will result in incomplete combustion and emissions discharged into the
room.
• All loose/broken bricks must be repaired ensuring the chimney is of sound construction and free from
leakage. Failure to do so may result in emission discharge into the room.
• The chimney must be free of soot and creosote accumulation resulting from previous slow combustion
wood fires. It must also be clear of all blockages and swept prior to installation.
• Any damper plate must be fixed in the open position or removed.
• Any underfloor air supply to the fireplace must be completely sealed off to prevent secondary air draw.
External Criteria:
• An approved chimney cap and cowl must be installed with this appliance. If there is an existing cap, it must
be free of defects/deterioration and repaired if found to be faulty.
• Inadequate chimney height can also effect product performance. Some applications may require the
chimney height to be extended to reduce possible down drafts.
• A flue draft smoke test must be carried out to confirm that an updraft occurs and the flue system is sound.
There must be no leakage of smoke through the structure of the chimney during or after the test. Inside,
upstairs and/or adjacent rooms should also be checked.
If any of the above criteria is not met, a Rinnai approved flue liner system
must be installed.
