Slimfire 252 Operation & Installation Manual
MASONRY FLUE INSTALLATION
Two masonry flue installation options are available. These are Open Chimney and Lined Chimney.
An ‘Open Chimney’ installation uses the natural draft properties of a sound chimney along with the addition of an
approved chimney plate and cowl to provide the flueing for the heater. If there is doubt as to the soundness of the
proposed chimney then a Rinnai Flexiliner FLFHA5FLEX should then be installed.
A ‘Lined Chimney’ installation is used when the existing chimney condition is inadequate for an Open Chimney’
installation and uses a Rinnai Flexiliner (flexible) flue system “FLFHA5FLEX” to provide the flueing for the heater,
refer to the instruction sheet provided with this kit for installation details.
OPEN INSTALLATION METHOD
The chimney must be physically checked first and must meet the following set criteria along with local regulations.
Failure to meet these criteria will not only void the product warranty but may affect the performance of the heater.
Chimney Criteria For Open Installation
• All loose/broken bricks must be replaced or repaired ensuring the chimney is of sound construction and does
not leak in accordance with AS/NZS 5601.
• Any under floor air supply to the fireplace must be completely sealed off to prevent secondary air draw.
• Total chimney height
MUST NOT
be less than 3 metres and flue cowl must terminate above the chimney in
accordance with AS/NZS 5601.
• The chimney must be swept clean and be free of soot and creosote that may have built up if previously used for
a solid fuel fire.
• The hearth surface must be flat and level to support the entire heater. If the heater is not properly supported
noise and vibration may result.
In a masonry fireplace, use a slurry of sand and cement to level the base as required.
