Resumen del manual
WARNING Fire Risk Asphyxiation Risk Do not draw outside combustion air from: • Wall, floor or ceiling cavity. • Enclosed space such as an attic or garage. • Close proximity to exhaust vents or chimneys. Fumes or odor may result. A. Install the Outside Air Kit Using an outside air kit is highly recommended to minimize the effects of negative pressure within the structure. We recommend you utilize the shortest duct run to optimize the performance of the outside air kit. Cold air flow can be minimized by putting a small dip in the duct creating a cold air trap. This trap can also help prevent heat build-up and exhausting out the intake due to the stack effect. The outside air kit inlet 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. In such an installation, a 3 ft (.914 m) height difference must be maintained from the top of the uppermost chimney section to the outside combustion air inlet. See Figure 4.2. See Figure 4.3 for proper placement of outside air inlet. The outside air kit is installed on the left hand side of the fireplace. See Figure 4.4 for handle location/operation. CAUTION Risk of Smoke Spillage Outside air inlet must be located to prevent blockage from: • Leaves • Snow/ice • Other debris Blockage may cause combustion air starvation.

Secure the Fireplace • Position the Fireplace This fi replace may be placed on either a combustible or noncombustible continuous fl at surface. Follow the instructions for framing in Section 3.D. Slide the fi replace into position. Be sure to provide the minimum air clearance at the sides and back of the fi replace assembly. See Section 3.B. Included with your fi replace you will fi nd two metal hearth strips measuring approximately 26 in. x 4 in. (660 mm x 102 mm). These strips are used to provide added protection where the fi replace and the hearth extension meet. Slide each metal strip 2 in. (51 mm) under the front edge of the fi replace. The individual pieces must overlap each other by 1 in. (25 mm) minimum in the middle of the fi replace to provide continuous coverage of the fl oor. See Figure 4.5. These metal strips should extend from the front and sides of the fi replace opening by 2 in. (51 mm). Note: When elevating the fi replace above the hearth extension the front of the elevated platform must be protected with a protective metal hearth strip as shown in Figure 4.6. Raised Platform Floor 2 in. (51 mm) 1 in. (25 mm) min. overlap 2 in. (51 mm) Top piece must overlap bottom piece Figure 4.6 Protect the Front of an Elevated Platform • Level the Fireplace Level the fi replace side-to-side and front-to-back. Shim with noncombustible material, such as sheet metal, as necessary. Secure the fi replace (using the nailing fl anges located on either side of the fi replace) to the vertical framing. Important: To ensure proper fi t of the glass doors, check the fi replace opening for square. Measure diagonal distances of the opening to make sure they are equal. If they are not, continue to shim the fi replace until those diagonals are equal. 1 in. (25 mm) overlap Metal strips are placed 2 in. (51 mm) under the front of the fireplace and must extend beyond the front and sides of fireplace opening by 2 in. (51 mm). Figure 4.5 Position the Protective Metal Hearth Strips • Place the Protective Metal Hearth Strips Fire Risk! • Prevent contact with sagging, loose insulation. • Do NOT install against vapor barriers or exposed insulation. WARNING Fire Risk! • Metal hearth strips MUST be installed. Sparks or embers may ignite fl ooring.
