Blower mixing tee

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, the system comprising:

• a blower assembly having a housing and a rotating impeller for creating a source of negative pressure within the housing, the housing having an inlet opening and an exhaust outlet;
• a dilution air inlet pipe having a first end configured to receive a supply of dilution air and a second end in communication with the inlet opening of the blower housing, the dilution air inlet pipe extending along a longitudinal axis, wherein the rotation of the impeller within the blower assembly creates a flow of dilution air in a first direction along the longitudinal axis of the dilution pipe from the first end to the second end;
• and
• a flue pipe having a first end configured to receive the exhaust gases from the exhaust flue of the heater and a second end in communication with the dilution air inlet pipe, the flue pipe extending along a longitudinal axis, wherein the rotation of the impeller in the blower housing creates a flow of exhaust gases that travels along the longitudinal axis of the flue pipe from the first end to the second end,
• wherein the longitudinal axis of the flue pipe is oriented at an angle relative to the longitudinal axis of the dilution air inlet pipe such that the flow of exhaust gases enters the inlet pipe against the flow of the dilution air.
