ODSR Series "A" Outdoor Woodburning Fireplace
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 ac-
complished — 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: Fireplaces may use Vermont Castings Group 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 applies 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" (235 mm). Mark
a spot on the ceiling directly above the fireplace. Draw a line
parallel to the back wall through this mark. (Fig. 12)
Using a plumb bob positioned directly over center point
of fireplace flue collar, mark the ceiling to establish the
chimney center point. (Fig. 12)
Offset Installation
In order to clear an obstruction, it may be necessary to
offset chimney from vertical. This is accomplished by us-
ing Vermont Castings Group 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.

Chimney Centerline
Actual Centerpoint
Fig. 12 Locate centerline of chimney with plumb line.
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 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 center
point. Go to floor above and see where hole will be cut.
Check to see where existing ceiling joists and other pos-
sible obstructions are located...i.e. wiring, plumbing etc...
If necessary, reposition chimney and/or fireplace to avoid
obstructions.
