MASONRY FIREPLACE INSTALLATIONS
1. Determine Chimney Size:
Use table 3 to determine the correct diameter
chimney for your fireplace.
2.
Mount Anchor Plate:
Chimneys for masonry fireplaces begin with an Anchor
Plate. Make sure the surface of the masonry chimney has a level surface on
which to attach the Anchor Plate. If the top of the masonry does not have a level
surface, then you will need to modify the masonry accordingly. Center the
Anchor Plate over the masonry flue opening, and seal the Anchor Plate with a
high-temperature (1000
℉
) sealant. Secure Anchor Plate with (4) ¼” x 2” masonry
anchors (Fig 26). It is very important that the Anchor Plate is level. Be sure to
maintain a 1” minimum clearance to combustibles from the Anchor Plate.
3.
Attach Chimney:
Twist lock the first chimney section clockwise onto the Anchor
Plate.
4.
Finish Chimney:
Install the rest of the chimney as directed in the Ceiling
Supported Installation section, Steps 4 through 10 (page 8-11). Refer to Figure 1
and Table 3 for chimney height requirements. Always maintain at least 2 inches
of clearance to combustible materials, and enclose the chimney where it passes
through occupied areas. Use a Wall Bracket for every 8 feet of chimney height.
