Abstract
A manifold gas valve for controlling gas flow to a burner has a diaphragm operated main valve, an electrically operated control valve, and means to delay the application of gas pressure to the main valve operating diaphragm to effect a delayed opening of the main valve. Opening of the control valve permits an immediate flow of gas to the main burner and simultaneously admits the application of gas pressure to effect a delayed opening of the main valve. The immediate flow of gas to the burner, which occurs upon opening of the control valve, is sufficient to effect reliable and timely ignition and support combustion.
