MASONRY FIREPLACE

USING DIRECT-CONNECT METHOD

This product conforms with the UL Standard for Safety 1482 (USA) and ULC S628 (Canada) in all respects, and is approved to UL & ULC safety standards for installation and use within a fireplace with a masonry chimney in accor- dance with NFPA 211, with or without a direct flue collar con- nection. A starter pipe is required to reach to the bottom of the existing flue.

1.Secure the fireplace damper in the open position. If this cannot be accomplished, it will be necessary to remove the damper.

2.Seal either the damper area around the chimney liner with a high temperature sealant or the fireplace front with fiberglass batting.

3.The chimney should be examined for cracks, loose mortar, and other signs of deterioration and blockage. The insert should not be installed until it is determined that the chimney is safe for use. Since an oversized flue contributes to the accumulation of creosote, the size of the flue should be checked to determine that it is not too large for the insert. The chimney should also be checked to ensure it meets the minimum standard of the National Fire Protection Association (NFPA) Standard 211. The following bullets list the more critical requirements for a properly constructed chimney:

•The masonry wall of the chimney, if brick or modular block, must be a minimum of 4 inches (102mm) nominal thickness. A chimney of rubble stone must be at least 12 inches (305mm) thick

•The chimney must have a fire clay flue liner (or equiva- lent) with a minimum thickness of 5/8” (16mm) and must be installed with refractory mortar. An equivalent liner must be a listed chimney liner system or other approved material.

•Cross-sectional area should be no more than 3 times the cross-sectional area of the flue collar of the insert. (28 sq inch flue area x 3 inches = 84 square inches maximum chimney area).

•A chimney inside the house must have at least two inches

(51mm) of clearance to the combustible structure. A chim- ney outside the house must have at least 1 inch (25mm) clearance to the combustible structure. Non-combustible fire stops must be installed at the spaces where the chim- ney passes through floors and/or ceiling (See Figure 8A and 8B on page 8).

NOTE: In Canada, a full reline is required.
