B. Clearances Minimum Clearances to Combustibles WARNING! Risk of Fire! WITHIN ENCLOSURE AREA You must comply with all minimum air space clearances to combustibles as specified in Figure 3.2. DO NOT pack required air spaces with insulation or other materials. Framing or finishing material used on the front of, or in front of, the fireplace closer than the minimums listed must be constructed entirely of non-combustible materials (i.e., steel studs, concrete board, etc.). Failure to comply may cause fire.
C. Construct the Chase Round Termination Cap A chase is a vertical boxlike structure built to enclose the fireplace and/or its vent system. Vertical chimneys that run on the outside of a building must be installed inside a chase. Storm Collar Metal Chase Top Ceiling Firestop In cold climates, Hearth & Home Technologies recommends that the chase be well insulated using batt type insulation between the joists. Construction of the chase may vary with the type of building.
D. Frame the Fireplace The finished cavity depth must be no less than 23 in. (584 mm) from the finished backwall to the outside of front wall framing. NOTICE: Hearth extension design must be determined before installation of fireplace. If the fireplace is placed on the floor the maximum height of a finished raised hearth is 2 in. (51 mm), if you want a higher raised hearth the fireplace must be placed on a platform. CAUTION! Risk of Cuts/Abrasions.
F. Protective Metal Hearth Strips WARNING! Risk of Fire! Protective metal hearth strips MUST be installed on combustible surfaces. DO NOT cover metal strips with combustible materials. Sparks or embers may ignite flooring. WARNING! Risk of fire! High temperatures, sparks, embers or other burning material falling from the fireplace may ignite flooring or concealed combustible surfaces. • Protective metal hearth strips MUST be installed. • Hearth extensions MUST be installed exactly as specified.
G. Outside Air Kit (optional) If you install an outside air kit, Hearth & Home Technologies recommends you utilize the shortest duct run to optimize the performance of the outside air kit. The outside air inlet hood should be positioned in a manner that will not allow snow, leaves, etc. to block the inlet. In some installations the air duct may need to be run vertically.
4 Chimney and Termination Requirements A. Chimney Requirements Vertical distances are measured from the base of the fireplace as shown in Figure 4.1. Table 4.1 Chimney Requirements Minimum overall straight height 16.5 ft 5.03 m Minimum height with single offset/ return 16.5 ft 45.03 m Double offset/return minimum height 20 ft 6.1 m Maximum height 90 ft 27.43 m Maximum chimney length between an offset and return 20 ft 6.1 m Maximum distance between chimney stabilizers 35 ft 10.
B. Offsets/Returns • • Use an offset/return to bypass overhead obstructions. An offset and return can be used as a single entity or separated by chimney section(s). WARNING! Risk of Fire! DO NOT use offset/returns greater than 30°. Chimney draft will be restricted and could cause overheating and fire. Secure offsets with screws ( not to exceed 1/2” / 13 mm in length) Secure returns with strapping. Straight chimney sections may be secured with screws. Keep chimney sections from separating or twisting.
C. Termination Requirements • Install a cap approved and listed for this fireplace system. Locate cap where it will not become plugged by snow or other materials. Locate cap away from trees or other structures. The bottom of the termination cap must be at least 3 ft (.91 m) above the roof AND at least 2 ft (.61 m) above any portion of roof within 10 ft (3.05 m). The distance required between caps is shown below. Slanted Roofs Chimney must extend 2 ft (.
5 Chimney Installation A. Typical Chimney System NOTICE: Chimney performance may vary. • • Trees, buildings, roof lines and wind conditions affect performance. Chimney height may need adjustment if smoking or overdraft occurs.
B. Assemble Chimney Sections Use only those components described in this manual. Substitute or damaged chimney components could impair safe operation and cause overheating and fire. Attach either a straight chimney section or an offset to the top of the fireplace (depending on your installation requirement). Chimney sections are locked together by pushing downward until the top section meets the stop bead on the lower section. The inner flue is placed to the inside of the flue section below it.
C. Secure Offset/Return When offsets and returns are joined to straight pipe sections, they must be locked into position with the screws (outer only). To prevent gravity from pulling the chimney sections apart, the returns and the chimney stabilizers have hanger straps for securing these parts to joists or rafters. See Figure 5.3. * Use # 6 or # 8 sheet metal screw, or larger, no longer than 1/2 in. (13 mm). ROOM ABOVE (non-insulated ceiling) B Ceilng firestop attached to bottom of framing 2 in.
