Abstract
An exhaust system for withdrawing a supply of exhaust gases from an exhaust flue of a heater and expelling the exhaust gases to atmosphere at a remote location that includes a mixing tee for mixing a flow of dilution air and a flow of exhaust gases. The mixing tee includes a first end coupled to the inlet opening of a blower housing and a second end coupled to a supply of dilution air. The dilution air inlet pipe of the mixing tee extends along a longitudinal axis. The mixing tee includes a flue pipe having a first end positioned to receive the exhaust gases from the heater and a second end that enters into the dilution air inlet pipe. The flue pipe extends along a longitudinal axis that is positioned at an angle relative to the longitudinal axis of the dilution air inlet pipe. The exhaust flue extends toward the upstream end of the dilution air inlet pipe such that the flow of dilution air impinges upon the flow of exhaust gases.
