Positioning, Safety Strips,

Securing the Fireplace

Slide fireplace into position.

Lift the fireplace front slightly and slide the metal safety strips under front bottom edge about 1¹⁄₂" (38 mm), al- lowing the remainder to extend in front of firebox. Over- lap strips at least 1/2" (13 mm) to provide a positive joint. (Flat safety strips are packed with fireplace.) (Fig. 13)

Safety strips are used to ensure that any combustible materials in front of the fireplace are protected even though a noncombustible hearth extension is required.

If fireplace is to be elevated above the floor, a “Z” shaped metal safety strip must be fabricated and used to protect combustible surfaces in front of the fireplace. This “Z” shaped safety strip is not provided but must be fabricated of metal with each horizontal leg at least 1¹⁄₂" (38 mm) wide and equal in length to the metals strips provided with the fireplace.

Note: Safety strips are not required over non-com- bustible floors where all supports at the base of the fireplace are noncombustible.

Eight (8) nailing flanges are supplied with the fireplace (found on the fireplace hearth). To level the box and secure it firmly in place, remove the nailing flanges from the hearth and install at the sides of the fireplace as shown in Figure 14.

Outside Air Kit

An outside air kit damper is installed in 424WBST Fire- places. If desired, or if local codes mandate the use of an air kit, then an AK-MST is required to complete the installation (from air kit to the outdoors). If the outside air kit is to be used, the AK-MST Air Termination Kit MUST be installed BEFORE the fireplace is enclosed. Refer to the AK-MST instructions for field installation. The outside air kit control is located in the lower left hand side of the fireplace behind the screen panel. (Fig.
