Connection To A Masonry Chimney - HearthStone Craftsbury 8390 Owner's Manual

ONNECTION O
Consider two primary
connecting your stove to a masonry chimney:
the chimney itself and the thimble where the
stovepipe connects to the chimney. Use only
Code approved masonry chimneys with a flue
liner.
Before connecting to a masonry chimney, hire a
professional to examine the chimney for cracks,
loose mortar, and other signs of deterioration
and blockage. If the chimney needs repair,
complete them before installing and using your
stove. Do not install your stove until the
chimney is safe for use.
Make sure the chimney's cleanout is complete
and working properly. To avoid a loss of draft,
the cleanout must close off completely.
allowed to cool, your stove will perform poorly
and creosote will build up in the chimney.
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) 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
