Note: SCL chimney cap is the same
as SC chimney cap except that the
SCL cap is a longer telescoping pipe
used in special installations (i.e. chase
installations)
CHIIMNEY INSTALLATION
1. Extend the regular chimney sections until the top of the chimney is 4"
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. Install the upper part of the flashing under the
shingles.
3. Set the flashing on the roof. Scribe a line around the flashing. Cut
1 /
4
" below the scribed line. This should increase the diameter of the
flashing outlet enough to allow the flashing to be placed over the
chimney. See Figure 25.
4. Snap the last section of inlet air duct in place. Slide flashing over the
chimney. Check for minimum clearances. Adjust chimney if neces-
sary to make minimum clearances.
5. Nail the flashing securely in place with eight (8) nails.
6. Seal crack between top of flashing and chimney with mastic. Leave
some extra mastic at this area to be used in step 8.
Be careful to avoid electrical shock
hazard when contacting wires to the
metal chimney components.
CAUTION
Use pliers and wear gloves when
handling the storm color The edge of
the storm color is sharp. If you are not
careful, you could cut your hands.

9. Place chimney cap into matching parts of the last chimney section. Push chimney cap down until the brackets on the
bottom of the chimney cap sits on the chimney pipe. Punch or drill 1 /
8
" diameter holes in the inlet air duct (chimney pipe)
where specified on the brackets. Fasten chimney pipe down with the No. 8 screws provided. Note: 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. Make sure none have been damaged or bent
during installation. Check to see that all parts have been properly installed.
Note: The metal used for chimney cap has a rust-protective coating but the cut edges of the parts are not
protected. Detergent-wash and paint exposed parts of chimney cap with galvanized primer paint.
This will prevent rusting and rust staining of nearby structures.
7. Place the storm collar around the chimney and put collar
together like a belt in belt loops. With the loops facing
up, slide the end of collar under the two loops on the
other end. 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.
Trim off the excess ends of the storm collar.
8. Slide storm collar down snugly against the flashing until
the excess mastic left in step six is forced up into crack
between the storm collar and chimney. This will make the
joint between the flashing and the chimney watertight.
See Figure 26.
