The inside dimension of the frame must be the same as the hole size selected from Figure 13 in order to provide required the 1¹⁄₂ inches of air space between the outside diameter of the chimney and the edges of the framed ceiling hole.

■5. 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", allowing 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. 14)

Majestic Fireplaces® SR/SC Series

Note: Safety strips are not required over non-combus- tible floors where all supports at the base of the fireplace are non-combustible.

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 15.

FORM

An outside air kit is installed in all SR/SC 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 MUST be installed BEFORE the fireplace is enclosed. Refer to the AK-MST instructions for field installation.

■6. Installing The Chimney System

Start by attaching the first chimney section to the collar on top of the fireplace.

Install the pipe as pictured in Figure 16. When you get a good lock, you will hear the pipe clearly snap

Fig. 14 Safety strip installation.

Safety strips are used to ensure that any combustible materials in front of the fireplace are protected even though a non-combustible hearth extension is re- quired.

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 metals strips provided with the fireplace.

together. Once sections are snap-locked in place, it is extremely difficult to get them apart. Make sure the pipe is firmly snapped and locked together as each pipe section is mounted.

When installing elbows, only outer pipe will snap- lock. Middle pipes simply slide into position. Be sure to always attach straps on upper elbow to a structural framing member. (Fig. 17)
