30°

5.Nail the support straps of the second elbow to a building frame member.
6.Continue installing the vertical portion of the chimney. See Figures 22 and 23.
Note: If the inclined portion of the chimney passes through a floor or ceiling, an SF30 firestop spacer should be installed to provide the firestop and support required. Be sure proper spacing in maintained between the chimney and combustibles. See Figure 23.
CHIMNEY CAP INSTALLATION
MODEL SC CHIMNEY CAP
Note: The proper chimney height is important to assure proper draft and safety.The chimney cap must extend the flue outlet 4" above the top of the last section of chimney. Keep this mind when determining the proper height for the chimney. The chimney should not be extended more than 90" above the supporting roof structure without additional support. In the case of an “A” frame type construction or other steep pitch roofs that require more than 90" of chimney above the roof, attach a support to the chimney at the 90" level that is strong enough to support a wind load of 31/8 pounds for each inch the chimney extends above 90". The flue outlet must be a minimum of 3' above the point where in penetrates the roof. See Figure 24.
