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.
. 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 (05mm) 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 times the
cross-sectional area of the flue collar of the insert. (28 sq
inch flue area x 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.
