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 in- staller 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

Installation other than as instructed by these instructions

Your DESA stove with B-vent burner system 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 stove with burner system and vent assembly must be vented directly to the outside. The venting system must NEVER be at- tached 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.

In absence of local codes, follow Section 7.0 of the current Na- tional Fuel Gas Code NFPA 54/ANSI Z223.1 and the Natural Gas Installation Code - vent sizings for Category I systems us- ing double wall B-1 vent pipe.

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-fam- ily dwellings.

Situate the gas vent in the structure so that it can be installed without cutting joists, sills, plates, or major load bearing parti- tions or members. It is also important to locate the base of the gas vent as near as possible to the heating appliance.

This burner system must be properly connected to a venting system. This burner system is equipped with a vent safety shutoff system.

Use only vents labeled "FOR EXTERIOR USE" above the roofline.

Consult the authority having jurisdiction to select the correct gas vent diameter. Avoid using a larger than necessary diameter.
