MULTIPLE HEATER VENTING (CONNECTIONS INTO A COMMON VENT OR MANIFOLD)

Requirements for venting of multiple heaters are the same as described for SINGLE HEATER VENTING except as follows:

1.The common vent size and total vent height is normally determined by the number of heaters per common vent, length of horizontal connector runs, and connector rise. Connector lengths should be as short as possible and have a minimum 1/2 inch per 20 foot fall. Without regard to connector rise and total vent height due to many possible venting configurations, the following should be observed:

a.Common vent pipe & vent connector diameter should be no less than that shown in the following Vent Sizing Table.

b.The connector length should be no more than 75% of the vertical portion of vent above the connector.

c.Where possible, use a Y-connector to the common vent.

2.Material for connectors should be constructed of galvanized sheet metal or other approved noncombustible corrosion resistant material as allowed by state or local codes. All common vent pipe should be double wall, Type B vent.

3.Avoid unnecessary bends. Limit to two (2) 90º elbows.

4.The entire length of vent connector shall be readily accessible for inspection, cleaning and replacement.

5.Groups of heaters with a common vent must be controlled by a common thermostat.
