INSTALLATION AND COMPONENTS

2)Acceptable Vent Connectors - The following may be used for vent connectors:

•Listed type B or L Gas Vent

•Single Wall Galvanized Pipe - Use 0.018” (26 gauge or heavier). The size and location of the chimney may not permit the use of a single wall connector in some cases. See Chapter 10 of the National Fuel Gas Code. Do not use single wall pipe for vent connectors in attics.

•Other Vent Connectors Permitted by the National Fuel Gas Code.

3)Chimney and Vent Connector Sizing - Size the chimney and vent connector in accordance with Chapter 10 of the National Fuel Gas Code.

4)Exterior Chimneys - An exterior chimney has one or more sides exposed to the outdoors below the roof line. There are two conditions under which an exterior chimney may be used:

•In some very restrictive cases, the AWI and TWI series boilers may be vented into an exterior ceramic lined masonry chimney. See Chapter 10 of the National Fuel Gas Code for information on when exterior chimneys may be used.

•An exterior masonry chimney may be used if it is lined with B vent or a listed chimney lining system.

5)This boiler may vented using a listed power venter. The power venter must be in sized and installed in accordance with the power venter manufacturer’s instructions, the terms of the power venter listing, and applicable codes. The boiler must be electrically interlocked with the power venter to prevent boiler operation if the power venter fails to operate. Before deciding to use a power venter, make certain that the flue gas exiting the power venter will not damage adjacent construction or other structures. Also make certain that the power venter terminal will not be subjected to winds which could effect power venter operation.

6)Do not connect the vent of this appliance into any portion of a mechanical vent system operating under positive pressure.
