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 inches, allow- ing the remainder to extend in front of ﬁrebox. Overlap strips at least 1/2 inch to provide a positive joint. (Flat safety strips are packed with ﬁreplace.) (Fig. 16)

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 inches wide and equal in length to the metal strips provided with the ﬁreplace.

NOTE: Safety strips are not required over noncombus- tible ﬂoors where all supports at the base of the ﬁre- place are noncombustible.

Four (4) 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 17.

Installing Outside Air Kit

An outside air damper assembly is installed in all SHR Series Fireplaces. 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 damper assembly to the outdoors). If the outside air kit is to be used, the AK-MST MUST be installed BEFORE the ﬁreplace is enclosed. Refer to the AK-MST instructions for ﬁeld installation. The outside air control lever is located in the center, just above the left side brick. To 'open', push control lever up and back. To 'close', pull lever forward and down. (Fig. 18)
