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.

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 ﬂue (the “breech”) must be lined with either a ceramic or metal cylinder, called the “thimble”, which is securely cemented in place. (Fig. 6) 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 25-51 mm (1-2”) 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.

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 nec- essary combination of mantel, trim, and connector heat shields to provide the required clearances. (Fig. 7)

•Double-check connector clearance from the ceiling.

•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 re-open the damper to inspect or clean the chimney.

Fireplace Installations -

Through the Fireplace

The Convection heater may be installed either without legs* as a ﬁreplace insert, or with standard legs at- tached - depending on the safety regulations that apply to your situation, the height of the ﬁreplace opening and your own preference. For either situation, the chimney connector/positive connection kit extends back from the stove, enters the ﬁreplace cavity, and turns upward. It then passes through the ﬁreplace damper opening and smoke chamber and connects to the chimney ﬂue.

In such installations, a “positive connection” must be made to the chimney ﬂue with a special kit available from your local dealer. Also, special clearance and ﬂoor protection provisions must be observed. These provi- sions are discussed in the Clearance and Floor Protec- tion sections respectively.
