VENTING INSTALLATION

WARNING: 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.

NOTICE: Failure to follow these instructions will void the warranty.

INSTALLATION PRECAUTIONS

Consult local building codes before beginning the installation. Only a qualified 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 roof tops

• 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 DESA International

• Installation other than as instructed by these instructions

Your fireplace is approved for use with any listed gas vent. A listed gas vent is a factory made and listed system designed, and installed exclusively for removing products of combustion, excess air, and dilution air resulting from burning fuel gas. Metal vents, the most common type of vent, employ

double wall construction enclosing an insulating air space. This air space both helps keep flue gases warm and reduce heat transferred to nearby combustibles. This appliance is equipped with a safety control system designed to protect against improper venting of combustion products.

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.

WARNING: This gas fireplace and vent assembly must be vented directly to the outside. The venting system must NEVER be attached to a chimney serving a separate solid fuel burning appliance.

TYPE B-VENT INSTALLATION (Listed B-0 or Greater)

Before beginning installation be sure that the overall height and gas vent size conform to building code requirements. Gas vents extending through pitched roofs can extend a minimum height of at least 600 mm (2') higher than any obstruction within 3m (10'). Gas vents extending through flat roofs are required to extend at least 600 mm (2') above the roof and at least 600 mm (2') higher than any portion of the building or adjoining building within 3m (10') of the gas vent.

• Venting instruction contained in this manual may or may not apply to your area. Consult your local authority for requirement in your area.

• Where the gas vent extends through accessible spaces, it should be enclosed to avoid personal contact and damage. Enclosure walls should have a fire rating equal to or greater than the floors through which the gas vent passes except in single or two-family dwellings.

INSTALLING VENT SYSTEM IN A CHASE

A chase is a vertical boxlike structure built to enclose venting that runs along the outside of a building. A chase is not required for such venting.

NOTICE: Treatment of firestops 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.

Note:

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. Minimum clearance between vent pipes and combustible materials such as insulation is 1".

CHIMNEYS

• Complete familiarity with chimney condition, height, size, clearance to combustibles and other factors is essential.

NOTICE: Consult the authority having jurisdiction in your area regarding masonry chimney venting applications.

NOTICE: A complete chimney inspection by a qualified person should be performed.

• Appliances using B-vent connectors to vent into a masonry or factory-built chimney should not exceed 1 1/2 feet in length for every inch of connector diameter (3" vent connector has a maximum 4 1/2 foot length; 5" connector has maximum 7 1/2 foot length).

• Oversized chimneys should be relined with appropriate listed relining systems.

• Cleanout access may be required.

RELINING SYSTEMS

• Suitability and approval of relining materials should be determined.

• Condition, size, height, and termination of the chimney to be relined must be determined.

• No substitution of components should be made.

• Joints and connectors should be made according to manufacturer’ s instructions.

NOTICE: Consult the authority having jurisdiction in your area regarding listed chimney liner venting applications.

WARNING: Operation of improperly installed and maintained venting system could result in serious injury, property damage, or loss of life.

CHECKING VENT CAPACITY

Complete all gas piping, electrical, and vent connections. After adjusting the fireplace and lighting the main burners, allow a couple of minutes for warm-up. Hold a lighted match just under the rim of the draft hood relief opening. Proper venting will draw the flame toward or into the draft hood. Improper venting, indicated by escape or spillage of burned gas, will cause match to flicker or go out. Smoke from a cigarette will also be pulled into the draft hood if the vent is drawing properly.
