the State of California to cause cancer, birth defects
and other reproductive harm.
California Health & Safety Code Sec. 25249.6
Fuels used in gas, wood-
Drafts
The fireplace should not be located in areas that create
drafts (ie: frequently opened doors and central heating air
inlets/outlets) that hamper the normal flow of air into the
fire.
Gas Logs
-
If you plan to install a gas log, the gas line should be
installed before framing the fireplace. The gas line must
be installed by a certified gas line installer.

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 1/2" (13 mm) from a
combustible back wall and 1/2" (13 mm) from a com-
bustible side wall or support. (Page 12, Fig. 19)
Planning the Chimney Run
WF288
Fig. 6 Installed lengths of chimney sections.
5. No more than 2 offsets (4 total 30° elbows in U.S./or
2 total 45° elbows in Canada) per fireplace may be
used.
6. A guy wire stabilizer is required for chimneys extend
ing more than 6' (1.8 m) above a roof line.
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. 7)
The key points of the "Ten Foot Rule" are:
1. If the horizontal distance from the chimney to the
peak of the roof is 10' (3 m) or less, the top of the
chimney must be at least 2' (610 mm) above the
peak of the roof, but never less than 3' (914 mm)
in height above the highest point where it passes
through the roof.
2. If a horizontal distance from the chimney to the peak
of the roof is more than 10' (3 m), a chimney height
reference point is established on the surface of the
roof a distance of 10' (3 m) from the chimney in a
horizontal plane. The top of the chimney must be
at least 2' (610 mm) above the reference point, but
never less than 3' (614 mm) in height above the high-
est point where it passes through the roof.
-
Determine how the chimney will be run, length of run
and chimney components required to complete the
job. (Fig. 5) Never install a chimney below minimum
heights.
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° from a
vertical plane.
3. A chimney may run straight up or it may be neces
sary to offset it to avoid obstructions.
4. The maximum length of an angled run (total chimney
system) is 20' (6 m).

Chimney Supports
The chimney system is supported by the fireplace for
vertical chimney heights less than 30' (9 m) above the
hearth. Chimney supports are required if the vertical
height exceeds 30' (9 m) with SK8 chimneys or 20' (6 m)
with 3-wall chimneys. Locate
chimney supports at ceiling holes or other structural framing at 30' (9 m) (SK8)
or 20' (6 m) (3-wall) heights. Spacing between chimney
supports must not exceed 30' (9 m) (SK8) or 20' (6 m)
(3-wall). Use Chimney Support Model SKCS8. (NOTE:
The SKCS8 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" (64 mm)
long when installed.)
Angled chimney runs require a support every 6' (1.8 m)
in addition to the elbow straps. Chimney supports are
used for this function. (Fig. 8)
Chase Installation
A chase is a vertical boxlike 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. (Page 4, Fig. 3)
If you need help in determining fireplace location or how
the chimney system should be run, contact your Majestic Fireplaces dealer for assistance.
Installation
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 noncombustible
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. 9)
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. 3)
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 INSULATED ENCLOSURE, BE SURE ALL RE
QUIRED AIR SPACES ARE MAINTAINED. (Page
12, Fig. 19)
