Securing the Connector
to a Masonry Chimney
The Dutchwest Convection heater may be connected
to either a freestanding masonry chimney or a masonry
ireplace chimney.
Freestanding Installations
If the chimney connector must pass through a combus-
tible wall to reach the chimney, follow the recommenda-
tions in the wall pass-through section that follows.
The opening through the chimney wall to the lue
(the “breech”) must be lined with either a ceramic or
metal cylinder, called the “thimble”, which is securely
cemented in place. (Fig. 7) Most chimney breeches
incorporate thimbles, but check to be sure the it is snug
and the joint between thimble and chimney wall irmly
cemented.
A special piece called the “thimble sleeve,” slightly
smaller in diameter than the standard connector and
most thimbles, will ease the removal of the chimney
connector 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 lush with the inner lue wall. Don’t extend it into
the actual lue passage, as that could interfere with the
draft.
The thimble sleeve should protrude 1-2” (25-50 mm)
into the room. 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.
Fireplace Installations -
Above the Fireplace
In this installation, the chimney connector rises from
the stove, turns ninety degrees, and goes back into the
ireplace chimney. The liner of the ireplace chimney
should extend at least to the point at which the chimney
connector enters the chimney. Follow all the guidelines
for installing a chimney connector into a freestanding
masonry chimney, and pay special attention to these
additional points:
•
Check the stove and chimney connector clearances
to combustible mantel or trim materials. Use the
necessary combination of mantel, trim, and connec-
tor heat shields to provide the required clearances.
(Fig. 8)
•
Double-check connector clearance from the ceiling.
•
The ireplace damper must be closed and sealed
to prevent room air from being drawn up the lue,
reducing the draft. However, it must be possible to
re-open the damper to inspect or clean the chimney.
