Claim 13:
14. A gas safety control system for a flame module comprising:
an oxidant gas safety controller configured to charge a first energy storage circuit when a first switch is powered, and configured to discharge the first energy storage circuit through an oxidant gas valve output as an oxidant gas valve signal to increase the flow rate of the oxidant gas through the oxidant gas valve when the first switch is switched from a powered state to an unpowered state; and
a fuel gas safety controller comprising:
a fuel gas valve signal output configured to output a fuel gas valve signal to a fuel gas valve for controlling a flow rate of a fuel gas through the fuel gas valve;
a second switch;
wherein when the second switch of the fuel gas safety controller is not powered, the fuel gas safety controller is configured to close the fuel gas flow valve.
