Masonry Fireplace Requirements

CANADA ONLY:
The fireplace insert must be installed with a continuous chimney liner of 6" diameter extending from the
fireplace insert to the top of the chimney. The chimney liner must conform to the Class 3 requirement of
Can/ULC S635, Standard Lining Systems for Existing Masonry or Factory- Built Chimney & Vents, or
CAN/ULC S640, Standard for Lining Systems for New Masonry Chimneys.

Chimney must have a clay tile liner or a stainless steel liner (positive connection).

Entire fireplace, including chimney, must be clean and undamaged. Any damage must be repaired
prior to the installation of the insert.

Chimney height: 15' (4.5M) minimum; 33' (10M) maximum.

The fireplace insert must be placed on a masonry hearth built to UBC standards.

Do not remove bricks or mortar from the existing fireplace.
EXCEPTION: Masonry or steel, including the damper plate, may be removed from the smoke
shelf and adjacent damper frame if necessary to accommodate a chimney liner, provided that the
removal will not weaken the structure of the fireplace and chimney, and will not reduce protection
for combustible materials to less than that required by the National Building Code.

Remove or lock the fireplace damper in the open position.

Permanently seal any opening between the masonry of the fireplace and the facing masonry.
