Figure 2 - Framing the Fireplace

Figures 2 and 2a show a typical framing of this fire- place assuming combustible materials are used. All required clearances to combustibles around the fire- place must be adhered to. A 1/2" air clearance must be maintained at the back and sides of the firebox assembly. A minimum of 38” is required to the bot- tom of a 7” mantle. Anything greater than 7” must be 42” above the base of the unit. Any framing on top of the fireplace must be above the top standoffs. Vent sections for a horizontal run require a 3" minimum air space on top and a 1" minimum air space on the sides and bottom. Vertical rise sections require a 1" minimum air space completely around the vent sec- tions.

Flue outside diameter: 8"

Minimum firestop framing: 10" X10"

Face of header to the center of the firestop spacer (FS6) framing: 87/8"

Note: The outside walls of the home around the fire place should be insulated and finished as one would any other outside wall, while maintain- ing the 1/2"air clearance around the firebox.

F. FINISHING MATERIALS

Only non-combustible materials may be used to cover the black surfaces of the fireplace front.

Combustible Finishing Material. Material made of or surfaced with wood, compressed paper, plant fibers, plastics, or any material capable of igniting and burning, whether flame proofed or not, plastered or unplastered.

Non-combustible Finishing Material. Material which will not ignite and burn. Such materials are those consisting entirely of steel, iron, brick, tile, con- crete, slate, glass or plasters, or combination thereof.

High Temperature Sealant Material. Sealants that will withstand high temperatures (300° F+); General Electric RTV103 (Black), or equivalent. Rutland, Inc. Fireplace Mortar #63, or equivalent.

After completing the framing and applying the finish- ing material (dry wall) over the framing, a non-com- bustible sealant, one-half inch wide maximum, must be used to close off any gaps at the top and sides between the fireplace and facing to prevent cold air leaks. See Figure 3.
