3. Install Wall Thimble: From the outside wall, put the outer half of the Wall
Thimble in the opening. Center the outer half of the Wall Thimble. Secure the
Wall Thimble to the outside wall with at least (4) 8 penny nails or (4) #8, 1-1/2"
screws. For concrete wall, Wall Thimble is not needed. The hole on the wall
just needs to be slightly larger than the chimney. Install the inner half (with
round plate) of the Wall Thimble in the inside wall surface, ensuring that the
shield slides into the shield of the outer half. Secure the Wall Thimble to the
inside wall with at least (4) 8 penny nails or (4) #8, 1-1/2" screws
4. Install Wall Support, Tee and Tee Cap: Assemble the Wall Support
(Figure 23) by attaching the 2 side brackets to the support plate, with the
hardware supplied (female coupler of the insulated coupling section is down).
Install one 6" Chimney Section (or longer as required) to the horizontal branch
of the insulated tee. Lock securely into the tee by twisting clockwise. A locking
band must then be installed at this connection. Make sure the clamp is facing
down to prevent any water from collecting in the locking band.
From outside the building, slide the chimney length (previously installed on a
tee) through the wall thimble ensuring the male coupling on a tee is facing
upward.
Install the male coupler of insulated coupling section on the support plate into
the female coupler of the Tee. Lock securely into the tee by twisting clockwise.
Place the assembled wall support against the wall (plate up) directly below the
insulated coupling section of the Wall Support. Tighten the insulated coupling
section and the support plate with supplied lag screws (14#, 2"). Then secure
the whole Wall Support assembly onto wall using 14#, 2" wood screws
through the pre-punched slots in each bracket. Important: Verify that Wall
Support is level, and secure the leg brackets of the Tee Support to the wall
(Figs 24). Finally, install Tee Cap into the female coupler of the insulated
coupling section. Lock securely by twisting clockwise.
5. Complete Chimney: Attach the Chimney Sections as in Step 7 in the
Ceiling Supported Installation section (page 7). Secure the chimney to the wall
with Wall Straps at a minimum of 8-foot intervals and maintain at least 2 inches
of clearance to combustible materials. Slip the Wall Straps around the chimney,
tighten the bolts, adjust the clearance, and fasten the Wall Straps to the wall
Once the chimney is at the minimum height specified in Figure 1, attach the
Chimney Cap onto the top of the chimney by holding it by the collar and twist
locking it clockwise onto the Chimney Pipe. If the chimney penetrates an
overhang, frame for at least 2 inches of clearance, and install Flashing and
Storm Collar as described in Steps 9 & 10 for Ceiling Supported Installations
(page
8).
Another option is to cut away the overhang for a 2-inch clearance
(Fig 25). If the chimney extends more than 5 feet above the top Wall Strap or
Flashing, use a Roof Brace.
6. Install Chase Top Flashing: It is recommended that a Tee Supported
Chimney be enclosed in a chase. If a chase enclosure has been constructed,
you can either use a standard flat-roof flashing, or you can use a Chase Top
