Two masonry flue installation options 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.

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, chimney plate and cowl to provide the flueing for the

heater.

Open Chimney Installation

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

and may void the warranty.

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 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 AS5601.

• 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.
