Securing the Connector to a Prefabricated Chimney

Follow the installation instructions of the chimney manufacturer exactly as you install the chimney. The manufacturer of the chimney will supply the accesso- ries to support the chimney, either from the roof of the house or at the ceiling of the room where the stove is installed.

Again, your dealer can supply a variety of specialty pieces to simplify the installation. Some adaptors, for example, enable you to make an attachment directly to the chimney or to the chimney’s ceiling support package. The bottom of the adaptor is screwed to the chimney connector. (Fig. 18)

Some pieces are designed so the top end will fit outside the inner wall of the chimney, and the bottom end will fit inside the first section of chimney connector. In this way, any soot or creosote falling from the inner walls of

the chimney will stay inside the chimney connector.

NOTE: For double-wall chimneys with an outside dimension greater than 10¹⁄₄", or with triple-wall chim- neys, check with the manufacturer of the chimney for

the right trim collar to finish the installation.

Securing the Connector to

a Masonry Chimney

Both freestanding masonry chimneys and fireplace masonry chimneys may be used for installation of your Vigilant II Coal Stove.

Freestanding: If the chimney connector must pass through a combustible wall to reach the chimney, follow the recommendations in the Wall Pass-Through sec- tion.

Fig. 19 The thimble, made of either ceramic or metal, must be cemented securely in place.

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 cement- ed in place. Most chimney breeches incorporate thim- bles, but check to be sure the fit is snug and the joint between thimble and chimney wall firmly cemented.

A thimble sleeve, available from your local dealer, will facilitate the removal of the chimney connector for inspection and cleaning. The thimble sleeve is slightly smaller in diameter than standard connector pipe and most thimbles.

It is installed by sliding it into the breech until it is flush with the inner wall. It should not extend into the actual flue passage, however, since this could interfere with the draft.

The thimble sleeve should protrude 1-2” (25-50 mm) into the room, and should be sealed in place with fur- nace cement and thin gasketing.

Once it the thimble sleeve is installed, the chimney con- nector should be attached to it with sheet metal screws.

Lacking a thimble, a suitable length of chimney con- nector can be extended through the breech to the inner face of the flue liner, and securely cemented in place. Additional pieces of connector are then attached with sheetmetal screws.

Above a fireplace

In this installation, the chimney connector goes up from the stove, turns 90 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
