V. Venting

A.General Guidelines.

1.Vent system installation must be in accordance with National Fuel Gas Code, NFPA 54/ANSI Z221.3, Part 7, Venting of Equipment; and/or CAN/CGA B149 Installation Codes, Section 7, Venting Systems and Air Supply for Appliances; or applicable provisions of local building codes. Contact local building or fire officials about restrictions and installation inspection in your area.

2.This appliance requires a Special Gas Vent. Use Vent Connector and Vent Terminal in Vent Accessory Carton provided with boiler (See Repair Parts, Key No. 8). The product is designed to use Burnham supplied AL 29-4C®Stainless Steel vent system components. The following manufacturers offer similar AL 29-4C®components and are approved for use with this product: Heat-Fab Inc. - Saf-T-Vent,

Flex-L International Inc., - Star-34, Protech Systems, Inc. - FasNSeal™, and Z-Flex U. S., Inc. - Z-Vent. The use of these alternate manufacturer's venting systems will require adapters to connect to the Burnham supplied vent connector and vent terminal. These adapters are not supplied with this unit and should be obtained from the supplier of the alternate manufacturer's venting system. See Table 5 for complete list of Burnham Vent System Components.

WARNING

Do not use this appliance with nonmetallic vent systems such as Hart & Cooley Ultravent, Plexco Plexvent, or Selkirk- Metalbestos Sel-Vent.
