Abstract
An appliance includes a first gas-burning heating element, a first gas path extending from an inlet to the first heating element, and a first solenoid valve positioned within the first gas path. The appliance further includes a second gas path extending from upstream of the first solenoid valve to the first heating element and supplying a base gas flow to the first heating element. A controller is electronically coupled with the first solenoid valve for controlling a supplemental flow of gas through the first gas path to the first heating element such that the supplemental gas flow combines with the base gas flow to achieve a total gas flow. The controller controls the supplemental flow to adjust the total gas flow by pulsing the first solenoid valve at a first rate corresponding to a desired rate of the total gas flow to the first heating element.
