3.2 Chimney Installation
The Elegance ST is approved with a 6” chimney that is
listed under the UL 103 / ULC S629 standards (refer to
Table 3-1). WARNING: Mixing chimney
components from different brands is a safety
hazard and will void the warranty on the unit. When
connecting the unit to an existing chimney, thoroughly
inspect the condition of the chimney and that the
installation conforms to the requirements of the
chimney manufacturer and the building codes. Note
that to avoid any unnecessary risk, it is often
recommended to replace the chimney system.
Always respect the clearances to combustibles from
the chimney manufacturers; a minimum clearance of 2
inches is usually required for prefabricated chimneys.
3.2.1 General Rules and Guidelines
1. Carefully read the instructions from the chimney
manufacturer prior to installation (manuals can be
obtained from the chimney manufacturer’s website
or from the vendor). Unless specified, follow the
chimney manufacturer’s instructions for proper
installation.
2. For optimal performance of the unit, it is
recommended to install the chimney system in an
interior setting. To prevent drafting issues and
creosote buildups, avoid exterior installations of
the chimney system in regions that experience
extreme cold conditions.
3. The minimum and the maximum height of the chimney from the base of the unit are 15 and 35 feet
respectively.
4. A minimum lengthof 12 inches of straight chimney is requiredfrom the top of the unit before having an offset.
5. Only chimneys approved under the UL 103 / ULC S629 standards can be installed onto the unit (refer to
Table 3-1 in Section 3.2.2).
6. A 6 inch anchor plate is required to connect the fireplace to the chimney system. The anchor plate can be
secured onto the unit with 4 self-tapping screws.
7. The chimney installed onto the unit cannot be connected to another appliance.
8. Enclose any portion of the chimney that extends to accessible spaces.
9. The clearance of the chimney to any combustible material cannot be less than 2 inches. WARNING: The 2
inch clearance cannot be filled with insulation or any non-combustible material.
10. At least one support is to be incorporated in any chimney installation.
11. A firestop is required in the joists/frames where the chimney goes through (ceilings, floors, walls, and attic).
Assure that the joist opening is constructed in a way that the firestop is overlapping by a minimum 1” (25
mm) on all 4 sides. A spacer shall provide for substantial continuous interference with the framed joist
opening for a height or depth of not less than 1” (25 mm). A joint between factory-made parts which provide
for firestopping is not to have a through opening greater than 1/8” (3 mm) wide. Refer to chimney
manufacturer’s installation instructions.
12. A roof assembly shall resist the accumulation of soot and debris therein when such accumulation obstructs
flue-gas or cooling-air passages. An opening, other than one for flue gas passage, shall not have an entrance
of a ½” (12.7 mm) diameter rod.
13. A roof and a vented flashing are required in the installation of the Elegance ST. A roof flashing assembly that
provides for ventilation shall be constructed so that soot or debris shall not accumulate on the assembly to
the extent that ventilation openings intended to remain open are obstructed. The ventilation shall be provided
by one or more fixed openings surrounding the chimney and the assembly shall comply with all of the
following:
