HearthStone STARLET Owner's Manual page 11

Whenever possible, choose an interior chimney. An
interior chimney heats up more quickly and retains its
heat; thus promotes a better draft and discourages the
formation of creosote. An exterior chimney does not
benefit from the warmth of being surrounded by the
building, so it typically operates at lower flue
temperatures than an interior chimney. An exterior
chimney's draft is not as strong and may experience
increased creosote accumulation.
When connecting the Starlet to a prefabricated metal
chimney, you must follow, precisely, the manufacturer's
installation instructions. Use only Type HT (2100 deg.
F), prefabricated metal chimneys listed per UL 103 or
ULC S629 standards.
¦ WARNING:
DO NOT CONNECT THE STOVE TO A
CHIMNEY FLUE SERVING ANOTHER
APPLIANCE.
Make sure the size of the chimney's flue is appropriate for
the Starlet. The Starlet requires a 6" (152 mm) inside
diameter flue for new installations. A 6" diameter flue
provides adequate draft and performance. You can use an
8" (203 mm) diameter existing flue with a reducer. An
oversized flue contributes to creosote accumulation. (In
this case, bigger is NOT better.)
When purchasing a prefabricated chimney to install with
your stove, be sure to also purchase from the same
manufacturer the wall pass-through (or ceiling support
package), "T" section package, fire-stops (when needed),
insulation shield, roof flashing, chimney cap, and any
other needed accessories. Follow the manufacturer's
instructions when installing the chimney and accessories.
In addition, be sure to maintain all manufacturers'
recommendations for the proper clearances to the
chimney.

Connection To A Masonry Chimney
Consider two primary elements when 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
