Abstract
A water heater has a gas burner in a combustion chamber below a tank. The burner has a venturi tube oriented in a collection housing, which receives a mixture of air and fuel from a duct at least partially protruding from a periphery of an exterior wall of the water heater. In some embodiments, the duct abuts the venturi tube within a collection housing in the combustion chamber.
