chimney. Chimney supports are
required for every 30 feet and 60 feet
chimney height above the hearth.
Determine the offset distance of your
chimney arrangement from the centerline of the fireplace to the centerline of
the chimney where it is to pass through
the first ceiling.
Note: This offset distance may not be
your full offset distance. See Examples

Planning Information
Preplanning an installation is very important to ensure
safety and to save time and money. An installer must
predetermine where a fireplace will be set and how the
chimney system will be run.
Mounting the Fireplace
A fireplace may only be mounted on the following
surfaces:
1. A flat combustible surface.
2. A raised wooden platform.
3. A concrete block or other solid object placed beneath
each of the four (4) corners of the fireplace.
The fireplace must be spaced 3/4 inch from a combustible back wall and 3/4 inch from a combustible side
wall or support. (Fig. 18, Page 13)
Planning the Chimney Run
Determine how the chimney will be run, length of run
and chimney components required to complete the job.
(Fig. 4) Never install a chimney below minimum
heights.

The Ten Foot Rule
Major U.S. building codes specify a minimum chimney
height above the roof top. The “Ten Foot Rule” is a fire
safety rule and not a draft rule. To ensure proper draft,
it is recommended that you always meet or exceed the
“Ten Foot Rule,” especially when installing a termination on a high pitch roof. (Fig. 6)
The key points of the "Ten Foot Rule" are:
1. If the horizontal distance from the center of the
chimney to the peak of the roof is 10 feet or less,
the top of the chimney must be at least 2 feet above
the peak of the roof, but never less than 3 feet in
height above the highest point where it passes
through the roof.
2. If a horizontal distance from the center of the
chimney to the peak of the roof is more than 10 feet,
a chimney height reference point is established that
is on the surface of the roof a distance of 10 feet
from the center of the chimney in a horizontal plane.
The top of the chimney must be at least 2 feet
above the reference point, but never less than 3 feet
in height above the highest point where it passes
through the roof.

In planning a chimney system, it is important to know:
1. The height of a chimney is measured from the hearth
to the exit point on the termination.
2. A chimney cannot be offset more than 30 degrees
from a vertical plane.
3. A chimney may run straight up or it may be necessary to offset it to avoid obstructions.
4. The maximum length of an angled run (total chimney
system) is 20 feet.
5. No more than 2 offsets (4 total 30˚ elbows in) per
fireplace may be used.
6. A guy wire stabilizer is required for chimneys extending more than 6 feet above a roof line.

Chimney Supports
The chimney system is supported by the fireplace for
vertical chimney heights less than 30 feet above the
hearth. Chimney supports are required if the vertical
height exceeds 30 feet with 11CF chimneys. Locate
chimney supports at ceiling holes or other structural
framing at 30 foot heights. Spacing between chimney
supports must not exceed 30 feet. Use Chimney
Support Model 11CS. (Note: The 11CS can not be
mounted directly to the fireplace.) Support provided
by elbow straps fulfills the support requirement only if
they are spaced as previously described. (A chimney
support is 2¹⁄₂" long when installed.)
Angled chimney runs require a support every six (6)
feet in addition to the elbow straps. Chimney supports
are used for this function. (Fig. 7)
Chase Installation
A chase is a vertical box-like structure which encloses
the fireplace and/or chimney. Chases are typically built
on the outside of the house with fireplace opening cut
into the outer wall of a room. (Fig. 2, Page 4)
If you need help in determining fireplace location or
how the chimney system should be run, contact your
Vermont Castings, Majestic Products dealer for assis-
tance.
Installation
1. Insulating Fireplace Enclosure
for Cold Climates
If you live in a cold climate, it is not required but
highly recommended that you insulate fireplace
enclosure to eliminate cold air penetration as much
as possible.
Insulate base of fireplace with a non-combustible
insulation rated for a minimum of 300° F. Insulating
is very important for outside wall installations over
a concrete slab. If fireplace is installed on a platform,
insulation should be placed on top of the platform
before fireplace is set. (Fig. 8)
When a fireplace is installed in a chase or on an
outside wall, enclosure should be treated like any
outside wall in a home. Insulation should be installed
on the inside wall as well as the outside wall(s). In a
chase, it is also a good idea to install a firestop at
the first ceiling level above the fireplace and enclose
the chase with sheeting material. Insulation may
then be installed above sheeting material to assure
the space around the fireplace is totally protected.
(Fig. 2)
When installing the chimney, DO NOT caulk between outer pipe and firestop. It is vital that some air
be allowed to flow through this very thin gap.
CAUTION: WHEN INSTALLING A FIREPLACE IN
AN INSULA TED ENCLOSURE, BE SURE ALL
REQUIRED AIR SPACES ARE MAINTAINED. (Fig.
17, Page 13)
