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 materi- als. 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 sup- ported by the ledge brackets. Refer to Figures 20 and 26 for details.

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 SEC- TIONS AND ELBOWS.

NOTE: STR33/36 and CVR36 models use CFM Cor- poration 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 indicate dimension X to locate the side wall framing. (Fig. 10) Be sure to observe clear- ance requirements for side and parallel combustible walls as noted in Page 16, Figure 23.

Offset Installation

In order to clear an obstruction, it may be necessary to offset chimney from vertical. This is accomplished by using CFM Corporation elbows. Use the 30° Offset Elbow table on Page 6 to determine proper offset and parts required.

Each offset requires two (2) elbows. The second elbow is equipped with support straps. It is very important to install the second elbow in each offset as close to the ceiling or support as possible so that the elbow straps can be secured to framing members to help support the weight of the chimney.

Determine offset distance of your chimney arrangement from centerline of fireplace to centerline of chimney where it is to pass through ceiling.

Locate center point of the chimney on ceiling as though a straight up chimney arrangement is to be used. Measure your offset dimension from the chimney center point on the ceiling.
