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 1

¹⁄₂

" (38mm), 

allowing the remainder to extend in front of firebox. 
Overlap 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 1

¹⁄₂

(38mm) 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 all STR 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 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. 
15) To operate, simply lift up to close or push down to 
open .
