ABSTRACT:
A control unit for controlling operation of a fuel-fired burner includes a housing having an air inlet which is open to an interior chamber of the housing. An air pump is positioned in the interior chamber of the housing and has an air inlet which is open to the interior chamber of the housing. The air pump generates reduced air pressure in the interior chamber which draws air into the housing and into the pump's inlet. This flow of air cools an electronic controller along with other components position in the housing. The air pump may be operated to draw air from the interior chamber of the housing and supplies the air to a combustion chamber of the fuel-fired burner to facilitate operation of the burner. An associated method of advancing air to a fuel-fired burner is also disclosed.
