Make sure the size of the chimney’s flue is
appropriate for this stove, and that it is not too large.
Use a masonry chimney with an 8" x 8" (203 mm x
203 mm) maximum tile size for best results. An
oversized flue will contribute to the accumulation of
creosote.
Use the following checklist to ensure that your
masonry chimney meets these minimum
requirements:
Chimney wall construction:
Brick or modular block at least 4" (102 mm) thick.
A mortared rubble or stone wall.
Flue
liner:
Minimum thickness of 5/8" (16 mm).
Installed with refractory mortar.
At least 1" (25 mm) air space.
An equivalent flue liner must be a listed chimney
liner system meeting type HT requirements or
other approved material.
Interior
chimney
requirements:
1. At least 2" (51 mm) clearance to combustible
structure.
2. Fire stops installed at the spaces where the
chimney passes through floors and/or ceiling.
3. 2" (51 mm) gap maintained to any insulation
from the chimney.
Exterior chimney requirements:
1. At least 1" (25 mm) clearance to combustible
structure.
Chimney height requirements: (See Figure
below)
1. At least 3 feet (0.9 m) higher than the highest
part of the roof opening through which it
passes.
2. At least 2 feet (0.6 m) higher than any part of
the roof within 10 feet (3 m) measured
horizontally from the top of the chimney.
This stove requires a minimum chimney height of 13
feet (4 m). The maximum allowable chimney height
is 30 feet (9m).
