(Fig. 7) The key points of the "Ten Foot Rule" are: 1. If the horizontal distance from the chimney to the peak of the roof is 10' (3m) or less, the top of the chimney must be at least 2' (610mm) above the peak of the roof, but never less than 3' (914mm) in height above the highest point where it passes through the roof. 2. If a horizontal distance from the chimney to the peak of the roof is more than 10' (3m), a chimney height reference point is established on the surface of the roof a distance of 10' (3m) from the chimney in a horizontal plane. The top of the chimney must be at least 2' (610mm) above the reference point, but never less than 3' (914mm) in height above the highest point where it passes through the roof.

STR/CVR Series Woodburning Fireplaces InstallationChimney Supports The chimney system is supported by the fireplace for vertical chimney heights less than 20' (6m) above the hearth. Chimney supports are required if the vertical height exceeds 20' (6m). Locate chimney supports at ceiling holes or other structural framing at 20' (6m) heights. Spacing between chimney supports must not exceed 20' (6m). Use Chimney Support Model SKCS8 for SK8 chimney, and Model 11CS for 11CF chimney. (NOTE: the chimney support can not be mounted directly to the fireplace.) Support provided by elbow straps fulfills the support requirement only if they are spaced as previously described. (A chimney support is 2..." (64mm) long when installed.) Angled chimney runs require a support every 6' (1.8m) in addition to the elbow straps. Chimney supports are used for this function. (Fig. 9) Chase Installation A chase is a vertical box-like structure which encloses the fireplace and/or chimney. Chases are typically built on the outside of the house with fireplace opening cut into the outer wall of a room. (Page 5, Fig. 4) If you need help in determining fireplace location or how the chimney system should be run, contact your Majestic dealer for assistance. Insulating Fireplace Enclosure for Cold Climates If you live in a cold climate, it is not required but highly recommended that you insulate fireplace enclosure to eliminate cold air penetration as much as possible. Insulate base of fireplace with a non-combustible insulation rated for a minimum of 300°F. Insulating is very important for outside wall installations over a concrete slab. If fireplace is installed on a platform, insulation should be placed on top of the platform before fireplace is set. (Fig. 9) When a fireplace is installed in a chase or on a outside wall, enclosure should be treated like any outside wall in a home. Insulation should be installed on the inside wall as well as the outside wall(s). In a chase, it is also a good idea to install a firestop at the first ceiling level above the fireplace and enclose the chase with sheeting material. Insulation may then be installed above sheeting material to assure the space around the fireplace is totally protected. (Fig. 4) When installing the chimney, DO NOT caulk between outer pipe and firestop. It is vital that some air be allowed to flow through this very thin gap. CAUTION: WHEN INSTALLING A FIREPLACE IN AN INSULATED ENCLOSURE, BE SURE ALL REQUIRED AIR SPACES ARE MAINTAINED. (Page 14, Fig. 20) Chimney Sup- port Strap SKCS8 FP284 Fig. 8 Chimney support installation Framing Framing can be constructed before or after the fireplace is set in place, however, most installers build the frame before setting the fireplace. Frame fireplace with 2 x 4 lumber or heavier materials. Refer to framing dimensions in Figures 1, 2, 3 or 4 for basic fireplace specifications. Headers and support studs must be turned on end as illustrated on Page 5, Figure 4. NOTE: Framing should be positioned to accommodate wall covering and fireplace facing material. Maintain 1/2" (13mm) air space between the outer dome and any combustible framing materials that may be supported by the ledge brackets. Refer to Figures 20 and 26 for details.

Hard, Flat Surface Insulation Plateform STR/CVR Series Woodburning Fireplaces Chimney Set-up Since you have already preplanned the chimney run, you should know exactly how the installation is to be accomplished — how much pipe is required, the number of elbows, if any, and type of termination to be used. CAUTION: REPORT TO YOUR DEALERS ANY PARTS DAMAGED IN SHIPMENT, SPECIFICALLY CHECK THE END CONNECTION OF CHIMNEY SECTIONS AND ELBOWS. NOTE: STR33/36 and CVR36 models use CFM Corporation SK8 (2-wall) chimney systems. STR/CVR42 Fireplaces use only model 11CF chimney system. Straight-Up Chimney Installation To locate the centerline of the flue put the fireplace in final position and place a plumb bob from the ceiling to the center of the fireplace flue collar. Mark this spot on the ceiling. Draw a line through that mark to either side of the firebox and ...
