Only noncombustible materials (i.e. brick, tile, slate, steel, or other materials with a UL fire rating of Zero) may be used to cover the black painted face of the appliance. It is permissible to bring combustible wall board to the top and side edges of the black painted face. A 300°F minimum adhesive may be used to attach facing materials to the black surface. If joints between the finished wall and the fireplace surround are sealed, a 300°F minimum sealant material (General Electric RTV103 or equivalent) must be used.

VENT INSTALLATION

Read all instructions completely and thoroughly before attempting installation. Failure to do so could result in serious injury, property damage or loss of life. Operation of improperly installed and maintained venting system could result in serious injury, property damage or loss of life.

WARNING

Failure to follow these instructions will void the warranty.

NOTICE

INSTALLATION PRECAUTIONS

Consult local building codes before beginning the installation. The installer must make sure to select the proper vent system for installation. Before installing vent kit, the installer must read this fireplace manual and vent kit instructions.

Only a qualified installer/service person should install venting system. The installer must follow these safety rules:

• Wear gloves and safety glasses for protection.

• Use extreme caution when using ladders or when on rooftops.

• Be aware of electrical wiring locations in walls and ceilings.

The following actions will void the warranty on your venting system:

• Installation of any damaged venting component.

• Unauthorized modification of the venting system.

• Installation of any component part not manufactured or approved by MHS.

• Installation other than permitted by these instructions.

This ﬁ replace must be vented to the outside. The venting system must NEVER be attached to a chimney serving a separate solid fuel burning appliance. Each gas appliance must use a separate vent system. Do not use common vent systems.

WARNING

12 74D0009

Horizontal sections of this vent system require a minimum of 3" clearances to combustibles at the top of the ﬂ ue and 1" clearance at the sides and bottom until the ﬂ ue penetrates the outside wall. A minimum 1" clearance all around the ﬂ ue is acceptable at this point of penetration.

WARNING

Vertical sections of this vent system require a minimum of 1" clearance to combustibles on all sides of the pipe.

VENT INSTALLATION

INSTALLATION PLANNING

There are two basic types of direct-vent installation:

• Horizontal Termination

• Vertical Termination

It is important to select the proper length of vent pipe for the type of termination you choose. It is also important to note the wall thickness.

FOR HORIZONTAL TERMINATION

Select the amount of vertical rise desired. All horizontal run of venting must have termination.

You may use up to three 90° elbows in this vent configuration. See Horizontal Termination Configurations on pages 17 and

18.

FOR VERTICAL TERMINATION

Measure the distance from the fireplace floor to the ceiling. Add the ceiling thickness, the vertical rise in an attic or second story, and allow for sufficient vent height above the roof line.

NOTE: You may use two 45° elbows in place of a 90° elbow . Y ou must follow rise to run ratios when using 45° elbows. The appliance is approved for use with three 90° elbows maximum or a combination of 90° and 45° elbows up to a maximum of 270°.

For two-story applications, firestops are required at each floor level. If an offset is needed in the attic, additional pipe and elbows will be required.

You may use a chase with a vent termination with exposed pipe on the exterior of the house. See Installing Vent System in a Chase below. If pipe is enclosed in chase, it is not exposed.

It is very important that the venting system maintain its balance between the combustion air intake and the flue gas exhaust. Certain limitations apply to vent configurations and must be strictly followed.

INSTALLING A VENT SYSTEM IN AN OUTSIDE CHASE

/4" rise for every 12" of run towards the

Never run the vent pipe level or downward. This may cause excessive temperatures which could cause a ﬁ re.

WARNING

A chase is a vertical boxlike structure built to enclose venting that runs along the outside of a building. A chase is required for such venting.

Treatment of ﬁ restops and construction of the chase may vary from building type to building type. These instructions are not substitutes for the requirements of local building codes. You must follow all local building codes.

NOTICE

When installing in a chase, you should insulate the chase as you would the outside walls of your home. This is especially important in cold climates. Insulation should be considered a combustible material. Maintain proper clearances to all combustible materials.
