CHASE FINISHING

If the chase is frame construction, the header over the chase opening must be a minimum of 66"

above the hearth floor. ½" masonry board should be installed over the entire area from the

header, between the studs, and up to the ½" offset ledge on the firebox. This board can be

screwed directly onto the fireplace face. The sheetrock can be butted up to the sides of the

fireplace. If installed on a wood floor, a hearth extension of 24" deep and extending 12" beyond

the hearth opening on both sides is required.

If the chase is masonry and the inside wall is extended above the fireplace, an adequate 1½ x

1½" L-iron mantle should be placed at the same height as the wooden header. Masonry board

covers the same opening.

THE FIREPLACE CANNOT BE USED AS ANY PART OF A

STRUCTUAL OR BEARING WALL

FIREBOX ASSEMBLY PROCEDURE

THE FIREPLACE SHOULD BE COMPLETELY ASSEMBLED

BEFORE BUILDING ANY CHASE OR FIREPLACE ENCLOSURE.

CONCRETE FLOOR INSTALLATION

If the fireplace is being installed flush with the floor, the supplied hearth split firebricks should be

laid out as illustrated in FIG 5, (pg. 5). They can be adhered to the floor with the refractory mortar

"Flue Glue" with a ¼"x ¼" tile applicator. After allowing to set, begin to assemble the firebox

starting with procedure #2, of the wood floor installation below.

WOOD FLOOR INSTALLATION

When the fireplace is being set over a wood floor, a heat barrier is required, see FIG 3 and FIG 4,

and step #1 below. Six sets of 2 split bricks 1¼" thick with a sheet of 24 gauge metal steel

sandwiched in between; which should be the same size of the base, and laid out as illustrated.

A hearth extension is required and must extend a minimum of 24" out from the face of the

fireplace and 12" beyond the fireplace opening on each side. The thickness of the extension shall

be a minimum of ½" masonry board and ¼" of ceramic tile or stone. The fireplace and hearth

extension can be raised to any height desired as long as the above specification are maintained

or increased.

The complete installation procedure following the installation of the heat barrier is shown and

described below.

Base

If the fireplace is being installed with the base(B), the hearth will be elevated 5" above the

finished floor. It can be elevated to any height desired by adding non-combustible bricks or

blocks under the base.
