Framing, Chimney Setup | Vermont Casting ODSR36A, ODSR42A guide

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.

NOTE: Framing should be positioned to accommodate wall covering and ﬁreplace facing material.

Chimney Setup

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 num- ber 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: Fireplaces may use CFM Corporation model SK8, or Model S (three wall) chimney systems. The ODSR Series "A" Fireplace will accept the SK8 chimney system as is; but a TWABR adapter collar is required when using the Model S (triple wall) chimney system. The installation procedure described in this manual ap- plies only to the SK8 system. Either chimney system may be used, but may not be mixed.

Straight-Up Chimney Installation

To mark the centerline of the ﬂue, put the ﬁreplace in ﬁnal position and measure out from the wall: 9¹⁄₄" (235mm). Mark a spot on the ceiling directly above the ﬁreplace. Draw a line parallel to the back wall through this mark. (Fig. 10)

Using a plumb bob positioned directly over center point of ﬁreplace ﬂue collar, mark the ceiling to establish the chimney center point. (Fig. 10)

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 5 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. Mea- sure your offset dimension from straight up chimney center point on ceiling.

Ceiling Chimney Hole/

Possible Obstructions

The size of the hole in ceiling will vary with the angle at which the chimney passes through ceiling.

Drive a nail up through ceiling at marked chimney cen- ter point. Go to ﬂoor above and see where hole will be cut. Check to see where existing ceiling joists and other possible obstructions are located...i.e. wiring, plumbing etc... If necessary, reposition chimney and/or ﬁreplace to avoid obstructions.
