securely in place. Most chimney breeches incorporate
thimbles, but the fit must be snug and the joint between
the thimble and the chimney wall must be cemented
firmly.
A special piece called the “thimble sleeve,” slightly
smaller in diameter than standard connectors and most
thimbles, will facilitate the removal of the chimney con-
nector system for inspection and cleaning. Thimble
sleeves should be available from your local dealer.
To install a thimble sleeve, slide it into the breech until
it is flush with the inner flue wall. Do not extend it into
the actual flue passage, as this could interfere with the
draft.
The thimble sleeve should protrude 25-51 mm (1-2”)
into the room. (Fig. 6) Use furnace cement and thin
gasketing to seal the sleeve in place in the thimble.
Secure the chimney connector to the outer end of the
sleeve with sheet metal screws.

Without a thimble, a suitable length of chimney con-
nector can be extended through the breech to the inner
face of the flue liner, and cemented securely in place.
Additional pieces of connector are then attached with
sheet metal screws.
Fireplace Installations
The chimney connector may be connected to the
chimney above the fireplace opening or through the
fireplace.
Above the Fireplace
The Encore Multi-Fuel may be connected to a chimney
above a fireplace opening. (Fig. 7) In such installa-
tions, the stove is positioned on the hearth in front of
the fireplace and the chimney connector rises from the
stove top and then angles ninety degrees back into the
chimney. The chimney liner should extend to the point
at which the chimney connector enters the chimney.

If the chimney connector from your installation enters
the chimney above a fireplace, follow all the guidelines
mentioned above for freestanding installations. In addi-
tion, give special consideration to the following points:
• Check the clearance between the stove and the
chimney connector, and any combustible trim or the
mantel. Use the necessary combination of mantel,
trim, and connector heat shields to achieve the required
clearances.
• Check the clearance between the chimney con-
nector and the ceiling. If no heat shields are used, the
clearance should be at least 24” (610 mm). To find out
how much this clearance may be reduced with heat
shields, see the clearance chart on Page 14.
