ChIMNey Cap INSTaLLaTION
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
Z\,
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.
. Remove the shingles from around the chimney so that the flashing may be installed, with the
upper part of the flashing under the shingles.
3. Set the flashing on the roof. Hold a section of the outside pipe (13” diameter) on the flashing
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.

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.
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 damaged 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 protected. 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.
