CHIMNEY CAP INSTALLATION
Model SC Chimney Cap
SPECIAL NOTE: The proper height as previously explained is important to assure proper draft and safety. The chimney
cap extends the flue outlet four inches above the top of the last section of chimney. This should be kept in mind when
determining the proper height for the chimney. The chimney should not be extended more than 90 inches 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 inches of chimney above the roof, a support should be attached to the chimney at the
90 inch level that is strong enough to support a wind load of 3-1/8 pounds for each inch the chimney extends above 90
inches. The flue outlet must be a minimum of three feet above the point where in penetrates the roof.
CAUTION: Be careful to avoid electrical shock hazard when contacting wires to the metal chimney components.
1. Extend the regular chimney sections until the top of the chimney is 4 inches below the total flue height desired. Do
not snap the last section of inlet air duct or largest diameter pipe in place until Step 3 is completed.
2. Remove the shingles from around the chimney so that the flashing may be installed, with the upper part of the flash-
ing under the shingles.
3. Set the flashing on the roof and scribe a line around the flashing, then cut the top off the flashing by cutting 1/4 inch
below the scribed line. This should increase the diameter of the flashing outlet sufficiently to allow the flashing to be
placed over the chimney. Figure 23
4. Snap the last section of inlet air duct in place and slide the flashing over the chimney. Adjust the chimney to assure
that the proper minimum clearances are maintained.

5. Nail the flashing securely in place with eight nails.

6. Seal the crack between the top of the flashing and the chimney with mastic. Leave some excess mastic at this area
������ ����
to be used in step eight. NOTE: Use pliers and wear gloves when performing step seven to minimize the danger of
cutting your hands on the edge of the storm collar. ����
7. Place the storm collar around the chimney and put the collar together like a belt in belt loops. Slide the end of collar
under the two loops on the other end with the loops facing up. Overlap the ends of the collar until it is tight against the
chimney. Bend the free end of the collar back over the loops to hold the storm collar securely together. The excess
end of the storm collar may be trimmed off.
8. Slide the storm collar down snugly against the flashing until the excess mastic left in step six is forced up into the
crack between the storm collar and the chimney. This should make the joint between the flashing and the chimney
watertight.
9. Install the chimney cap by placing the cap into matching parts of the last chimney section. Push down until the brack-
ets on the bottom of the chimney cap sit on the chimney pipe. Then punch or drill 1/8 inch diameter holes in the inlet
air duct (chimney pipe) where specified on the brackets and fasten it down with the No. 8 screws provided. Do not
penetrate the inner stainless steel pipe while installing the screws.
10.Check all the parts of the fireplace, chimney and chimney termination cap to assure that no parts have been dam-
aged or bent during installation and that all parts have been installed properly.
NOTE: The metal used for the chimney cap has a rust protective coating but the cut edges of the parts are not pro-
tected. To prevent rusting and rust staining of nearby structures, exposed parts of the chimney and chimney cap should
be detergent washed and painted with a galvanized primer paint.
