Masonry Chimney Liner

For optimal performance, masonry chimneys used to vent this appliance should be:

1.	Lined with a 6 inch (152mm) stainless steel liner.
	• Installations into a clay fl ue without a stainless steel
	liner may reduce draw which affects performance,
	cause the glass to darken and produce excessive
	creosote.
2.	It is recommended that a chimney with a larger diameter

than 6 inches (152mm) be relined.

• The oversized fl ue can cause poor performance and

contribute to the accumulation of creosote.

3. Have the chimney cleaned before the stove is installed

Chimney Height / Rise and Run

This product was designed for and tested on a 6 inch (152mm) chimney, 12 to 14 feet (420-480cm) high, (includes stove height) measured from the base of the appliance to the the top of the chimney (not including chimney cap). The further your stack height or diameter varies from this confi guration, the possibility of performance problems exists.

Chimney height may need to be increased by 2 - 3% per each 1000 feet above sea level. It is not recommended to use offsets or elbows at altitudes above 4000 feet above sea level or when there are other factors that affect fl ue draft.

and operated.

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 fi re clay fl ue liner (or equivalent) with a minimum thickness of 5/8 inch (16mm) and must be installed with refractory mortar.

•An equivalent liner must be a listed chimney liner system or other approved material.

•Since an oversized fl ue contributes to the accumulation of creosote, the size of the fl ue 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.

•A chimney support package must be used when a connection is made through the ceiling to a factory built chimney.

•An approved thimble and chimney support package are absolutely necessary to provide safe clearances to combustible wall and ceiling material.

NOTICE: In Canada, the installation shall conform to CAN/CSA-B365.

NOTICE: Check with your local building authorities and/or consult the National Fire Protection Association (NFPA 211).
