Chimney
The RAIS stoves must be installed using a Class A UL 103 HT
approved factory-built chimney system or a code-approved
masonry chimney with a flue liner. In Canada, the installation must
conform to CAN/CSA-B365.The chimney must extend through the
roof at least 3’ (1m), and 2’ (.6m) above any structure within 10’
(3m).
The condition of the chimney and height is very important. We
suggest a total minimum height of 10’ (3m). Do not connect this
stove to a chimney flue serving another appliance.
Required Installation Components

For venting vertically into a Class A chimney, single wall pipe (at least 24 gauge) may be
used in the room where the stove is installed. Refer to the manufacturer’s instructions for
the connection to the listed chimney. The chimney/stove pipe must not be smaller than 6”
(15cm) in diameter.
For venting directly into a masonry chimney or through a thimble, the top of the single wall
pipe must be at least 18” (46cm) below a combustible ceiling and conform to NFPA 211
guidelines and methods. See diagram below.
For rear venting or other not listed configurations, consult the local building codes and
follow the NFPA 211 guidelines.
