Vermont Casting 1990 installation instructions Fireplace Chimney Installations Above a Fireplace

The opening through the chimney wall to the flue (the “breach”) must be lined with either a ceramic or metal cylinder, called the “thimble”, which is cemented firmly in place. The fit must be snug and the joint between the thimble and the chimney wall must be cemented. (Fig. 6)

A special piece called the “thimble sleeve,” slightly smaller in diameter than standard connector 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. (Fig. 5)

To install a thimble sleeve, slide it into the breach 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 1-2” (25-50mm) into the room. Use furnace cement and thin gasketing to seal the sleeve in place in the thimble. Secure the chim- ney 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 breach to the inner face of the flue liner, and cemented securely in place. Additional pieces of connector are then attached with sheet metal screws.

Above a Fireplace

The Intrepid II may be connected to a chimney above a fireplace opening also. In such installations, 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. (Fig. 7)

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 26” (660mm). To find out how much this clearance may be reduced with heat shields, see the clearance chart on Page 14.

•The fireplace damper must be sealed to prevent room air from escaping up the flue. However, it must be possible to re-open the damper to inspect or clean the chimney.
