CHIMNEY CAP CHASE INSTALLATION
The preinstalled chimney sections should be no more than 13” below the top of the chase.
The installation should be planned so that either a two-foot or three-foot chimney section will
be used for the top section. This is necessary to ensure complete engagement of the inlet air
telescope and chimney cap into the top section.
1. Extend the chimney sections until the top of the chimney is not more than 13” below the top
of the chase.
2. Center the hole in the chase cover over the chimney. The chase cover overhang should be
lanced, formed over the chase and secured with nails. This prevents water from seeping
under the chase cover. If two or more chase covers are to be used on the same chase, they
should be soldered together to form two watertight seams.
3. Place the outer telescope inside the hole in the chase cover and lower it down into the mat-
ing pipe of the chimney until the support brackets on the telescope section rest on the flange
of the chase cover.
4. Bend the tab with a hole on each bracket outward and secure cap to flashing, using the tabs
provided.
5. Once the telescope is secured, place the rain shield over the top of the telescope pipe as-
sembly. The rain shield will be supported by the telescope brackets.
CAUTION:
Be careful around electrical wires to avoid the electrical shock hazard of contacting
the wires with the metal chimney components.
NOTE:
When two fireplace chimneys are terminated above the same chase, the centers of the
chimney caps should be at least 24” apart to help prevent smoke from a fireplace in use from
being drawn down the chimney of a fireplace that is not in use. Additional spacing between
caps or staggering the height of the caps will further lessen the likelihood of this occurring.
6. Place cap assembly into position by aligning the flue telescope into the last section of flue
pipe and lower it down until the 3 cap legs rest on the top edge of the outer telescope pipe.
Secure legs of cap to the telescope with screws provided.
7. Check all parts of the chimney and chimney 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 and 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 struc-
tures, exposed parts of the chimney and chimney cap should be detergent-washed and painted
with galvanized primer paint.
