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 chim-
ney 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 possible obstructions are located...i.e. wiring,
plumbing etc... If necessary, re-position chimney and/or
fireplace to avoid obstructions.
2. 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 or 3 for
basic fireplace specifications.
Note: Framing should be positioned to accommodate
wall covering and fireplace facing material.
3. 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.
Note: ODSHR Series Fireplaces must use Vermont
Castings, Majestic Products model 11CF, 11 inch, 2 wall
chimney systems. The installation procedure described
in this manual applies only to the 11CF system, chim-
ney components 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 11¹⁄₈". Mark
a spot on the ceiling directly above the fireplace. Draw
a line parallel to the back wall through this mark. (Fig.
9)
Using a plumb bob positioned directly over center point
of fireplace flue collar, mark the ceiling to establish the
chimney center point. (Fig. 9)
Offset Installation
In order to clear an obstruction, it may be necessary to
offset chimney from vertical. This is accomplished by
using Majestic elbows. Use the
30˚ Offset Elbow
table
on Page 5 to determine proper offset and parts re-
quired.
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.
