CHIIMNEY INSTALLATION
CHIMNEY CAP CHASE INSTALLATION
The preinstalled chimney sections must be no more than 10" below the top of the chase. Plan the installation so that either
a 2' or 3' chimney section will be used for the top section. This is necessary to completely install inlet air telescope and
chimney cap into the top section.
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
fireplace in use from being drawn down the chimney of
fireplace that is not in use. Additional spacing between
caps or staggering the height of the caps will also
help.
1. Extend the chimney sections until the top of the chimney is not more than 10" below top of the chase.
2. Center the hole in the chase cover over the chimney. Lance and form chase cover overhang over the chase. Secure chase
cover overhang with nails. The chase cover overhang keeps water from seeping under the chase cover. If two or more
chase cover overhangs are to be used on the same chase, solder the chase covers together to form watertight seams.
3. Place the inlet air telescope inside the hole in the chase cover. Lower inlet air telescope down into the mating pipe of
the chimney until flange on the telescope section rest on flange of the chase cover overhang.
Note: All telescoping sections should extend a minimum of 3" inside the mating chimney pipes.
4. Place SCL or SQL8 chimney cap into matching duct telescope and flue telescope of the last chimney section. See Figure
27. Lower the cap until the brackets on the bottom of the chimney cap rests on the raised flange of the flat flashing.
Punch or drill
1
/8" diameter holes in the raised flange of the flat flashing. Fasten cap to the flashing with the No. 8 screws
provided.
5. Check all parts of the chimney and chimney cap. Make sure none have been damaged or bent during installation. Check
to see 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. Detergent-wash and paint exposed parts of the chimney and chimney cap
with galvanized primer paint. This will prevent rusting and rust staining of nearby structures.
Be careful around electrical wires
to avoid the electrical shock hazard
of contacting the wires with the
metal chimney components.
