INSTALLATION OF LISTED B-1 VENT

INSTALLING VENT SYSTEM IN A CHASE

WARNING: Installation should only be made by qualified persons who are familiar with the safety procedures required for the installation of the prod- uct, who are equipped with the proper tools and testing instruments, and who have achieved proper certification of licensing. Installations made by un- qualified persons can result in the risk of injury or electrical shock which can be serious or even fatal.

Figures 21 through 23 show other options for the gas vent. When venting through a side wall your vent pipe must have the proper temperature rating (see Figure 23). Manufacturer's clearances must also be maintained. Consult the authority having jurisdiction in your area regarding venting through side wall.

A chase is a vertical box-like 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 fol- low 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".

CHECKING VENT CAPACITY

Complete all gas piping, electrical, and vent connections. After adjust- ing the burner system 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 burnedgas,willcausematchtoflickerorgoout.Smokefromacigarette will also be pulled into the draft hood if the vent is drawing properly.
