BR/BC36 BR/BC42
C. The chimney cannot be more than 30˚ (45˚ in Canada) from the vertical plane in any installation*.
D. The maximum length of the angled run of the total chimney system is 20 feet. (G plus H cannot exceed 20 feet.)
E. A chimney support (Model SKCS8) is required every 6 feet of angled run of chimney. Chimney supports are required for every 30 feet and 60 feet (SK8 pipe) or 20 feet and 40 feet (3-wall pipe) of ver­tical 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 2 and 3.

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" (13mm) from a com­bustible back wall and 1/2" (13mm) from a combustible side wall or support. (Page 14, Fig. 20)
Planning the Chimney Run
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. 8)
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' (3m) or less, the top of the chimney must be at least 2' (610mm) above the peak of the roof, but never less than 3' (914mm) 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' (3m), a chimney height reference point is established on the surface of the roof a distance of 10' (3m) from the chimney in a horizontal plane. The top of the chimney must be at least 2' (610mm) above the reference point, but never less than 3' (914mm) in height above the high­est point where it passes through the roof.
Fig. 7 Installed lengths of chimney sections.
Determine how the chimney will be run, length of run and chimney components required to complete the job. (Fig. 6) 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 neces­sary to offset it to avoid obstructions.
4. The maximum length of an angled run (total chimney system) is 20' (6 m).
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 extend­ing more than 6' (1.8 m) above a roof line.

Chimney Supports
The chimney system is supported by the fireplace for vertical chimney heights less than 30' (9m) above the hearth. Chimney supports are required if the vertical height exceeds 30' (9m) with SK8 chimneys or 20' (6m) with 3-wall chimneys. Locate chimney supports at ceil­ing holes or other structural framing at 30' (9m) (SK8) or 20' (6m) (3-wall) heights. Spacing between chimney supports must not exceed 30' (9m) (SK8) or 20' (6m) (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" (64mm) long when installed.)
Angled chimney runs require a support every 6' (1.8m) in addition to the elbow straps. Chimney supports are used for this function. (Fig. 9)
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. (Page 5, Fig. 5)
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. 10)
When a fireplace is installed in a chase or on a 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. 5)
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 REQUIRED AIR SPACES ARE MAINTAINED. (Page 14, Figure 20)
