galvanized sheet using appropriate sheet metal screws and non-hardening
waterproof sealant. Use the Chase Top Flashing Spacers to allow the proper
air-gap clearances on the galvanized sheet. The Chase Top Flashing Spacers
are available to insure that the proper air-gap is maintained. Figure 26 displays
in some detail, how these air gaps are established using the Spacers and
Chase Top Flashing. Secure the Chase Top Flashing to the chase using a
sufficient number of #8, 1-1/2" wood screws, being careful to insure the air gap
is maintained between the flashing and the chase. Seal the screw heads with
non-hardening sealant. When installing the Storm Collar, allow a 1" air space
between the bottom of the Storm Collar and the Chase Top Flashing.
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
0
Plate with a high-temperature (1000
F) sealant. Secure Anchor Plate with (4)
1/4" x 2" masonry anchors (Fig 27). It is very important that the Anchor Plate is
level. Be sure to maintain a 1" min. clearance to combustibles from the Anchor
Plate.
