Abstract
A heater venting system comprises an exhaust blower, an exhaust pipe, and an acoustic shunt. An exhaust passageway of the exhaust pipe is in fluid communication with the blower discharge. The acoustic shunt includes a pipe section having a shunt chamber of a shunt chamber length. The shunt is coupled to the exhaust pipe such that the shunt chamber is in fluid communication with the exhaust passageway such that the shunt chamber extends generally laterally from the exhaust passageway. The shunt chamber length is sized to attenuate the noise of the heater venting system.
