Framing
Framing can be constructed before or after the fire-
place 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 or 2 for
basic fireplace specifications. Headers and support
studs must be turned on end as illustrated in Figure 2,
Page 4.
NOTE: Framing should be positioned to accommo-
date wall covering and fireplace facing material.
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 DEALER ANY
PARTS DAMAGED IN SHIPMENT, SPECIFICALLY
CHECK THE END CONNECTION OF CHIMNEY
SECTIONS AND ELBOWS.
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. 8) Be sure to observe clear-

ance requirements for side and parallel combustible
walls as noted in Figure 20, Page 15.
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 the elbow straps can
be secured to framing members to help support the
weight of the chimney.
Determine offset distance of your chimney arrange
-
ment from centerline of fireplace to centerline of chim-
ney 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 chim-
ney center point on the ceiling.
