Securing the Connector to a Masonry Chimney
The Dutchwest Convection heater may be connected to either a freestanding masonry chimney or a masonry fireplace 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
The opening through the chimney wall to the flue (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 fit is snug and the joint between thimble and chimney wall firmly 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 flush with the inner flue wall. Don’t extend it into the actual flue passage, as that could interfere with the draft.
The thimble sleeve should protrude

Above the Fireplace
In this installation, the chimney connector rises from the stove, turns ninety degrees, and goes back into the fireplace chimney. The liner of the fireplace 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)
•
•The fireplace damper must be closed and sealed to prevent room air from being drawn up the flue, reducing the draft. However, it must be possible to
