| 主权项 | 1. A burner assembly, comprising: a burner unit; a fuel supply attached to the burner unit and including a gas valve, an air intake, and a mixing portion in which gas and air are mixed; a choke movable relative to the air intake to adjust an amount of air entering into the air intake port; and an electronic controller to control the movement of the choke relative to the air intake, wherein the controlled movement includes momentarily moving said choke from a first position prior to activation by said electronic controller to a second position that reduces an amount of air entering the intake for a momentary pre-flow period when a cold start condition exists. | ||
