Monessen Hearth BWBC400I, BWB400I manual Chimney CAP Chase Installation

CHIMNEY CAP CHASE INSTALLATION

The preinstalled chimney sections should be no more than 10 inches below the top of the chase. The installation should be planned so that either an 18-inch or 36-inch 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.

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 inches 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.

1.Extend the chimney sections until the top of the chimney is not more than 10 inches 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 inlet air telescope inside the hole in the chase cover and lower it down into the mating pipe of the chimney until the flange on the telescope section rest on the flange of the chase cover. Note: All telescoping sections should extend a minimum of three inches inside the mating chimney pipes.

4.Install the SCL or SQL8 chimney cap by placing the cap into the matching duct telescope and flue telescope of the last chimney section as shown by Figure 23. 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 inch diameter holes in the raised flange of the flat flashing, and fasten the cap to the flashing with the No. 8 screws provided.

5.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 structures, exposed parts of the chimney and chimney cap should be detergent-washed and painted with galvanized primer paint.
