Safety Information

PLEASE READ THIS MANUAL BEFORE INSTALLING AND USING FIREPLACE.

IMPORTANT: Read all instructions and warnings carefully before starting installation. Failure to follow these instructions may result in a possible fire hazard and will void the warranty.

Description

The SR/SC Series "A" fireplaces are solid fuel, woodburning premium fireplaces. The SR36A/42A are radiant clean-face models and the SC36A/42A are circulating models with removable grilles (louvres). Both models are fully insulated fireplaces.

Precautions

CFM Corporation fireplaces and component parts have been highly tested and will operate safely when installed in accordance with instructions provided in this manual. Carefully read and understand all instructions before beginning installation.

If you notice any damage to fireplace or component parts, immediately report damage to your Majestic Fireplaces dealer.

Only use CFM Corporation components or the warranty will be voided and a fire hazard may be created.

CFM Corporation warranty will be voided by and CFM Corporation disclaims any responsibility for the following actions:

•Installation of any damaged fireplace or chimney component;

•Modification of fireplace, chimney assembly or any component parts thereof; (except for chase flashings as detailed in Chimney Top installation instructions).

•Installation other than as instructed by CFM Corporation; or

•Installation and/or use of any component part not manufactured or approved by CFM Corporation in combination or assembly with a Majestic Fireplaces fireplace system, notwithstanding any independent testing laboratory or other third party approval of such component parts or accessory.

Any such action may possibly cause a fire hazard.

Consult local building codes to ensure that you are in compliance before installing the fireplace.

Fireplaces must be vented to the out-of-doors.

Do not obstruct or modify air inlets/outlets in any manner.

Do not install combustible materials on any of the black fireplace surround.

Burn only solid wood fuel or gas logs.

Do not install a solid fuel burning insert or other products not specified for use with this fireplace.

Proposition 65 Warning: Fuels used in gas, woodburning or oil fired appliances, and the products of combustion of such fuels, contain chemicals known to the State of California to cause cancer, birth defects and other reproductive harm.

California Health & Safety Code Sec. 25249.6

WARNING: Check with your electronics manufacturer before installing a television or other electronic device above this fireplace.

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" (13mm) from a combustible back wall and 1/2" (13mm) from a combustible side wall or support. (Page 14, Fig. 20)

WF288

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' (6m).

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' (1.8m) 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. 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' (614mm) in height above the highest point where it passes through the roof.

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⁄" (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 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. 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, Fig. 20)
