CR Series Woodburning Fireplaces
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 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 accommodate
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 ac-
complished — 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 clearance
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 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.
