For gas appliances, a flame supervision device (FSD) – alternative name: flame failure device (FFD) – is a general term for any device designed to stop flammable gas going to the burner of a gas appliance if the flame is extinguished. This is to prevent a dangerous buildup of gas within the appliance, its chimney or the room. [1]
Gas stoves today use two basic types of ignition sources, standing pilot and electric. [21] A stove with a standing pilot has a small, continuously burning gas flame (called a pilot light) under the cooktop. [21] The flame is between the front and back burners. When the stove is turned on, this flame lights the gas flowing out of the burners.
Flame rectification occurs when electrons flow through the flame burning, which the ignition controller senses and knows the flame is there, keeping the gas valve open. If the appliance loses gas or the flame goes out, the ignition controller does not see the flame, closing the gas valve. A red-hot surface can also be used to provide ignition.

Static instability [2] or flame blow-off refer to phenomena involving the interaction between the chemical composition of the fuel-oxidizer mixture and the flow environment of the flame. [13] To explain these phenomena, consider a flame that is stabilized with swirl, as in a gas-turbine combustor , or with a bluff body .
Wand lighter. A gas lighter is a device used to ignite a gas stove burner. It is used for gas stoves which do not have automatic ignition systems. It uses a physical phenomenon which is called the piezo-electric effect to generate an electric spark that ignites the combustible gas from the stove’s burner.
A "drop-in range" is a combination stovetop-and-oven unit that installs in a kitchen's lower cabinets flush with the countertop. Most modern stoves come in a unit with built-in extractor hoods. Today's major brands offer both gas and electric stoves, and many also offer dual-fuel ranges combining a gas stovetop and an electric oven.
Some combined main burner and pilot gas valves (mainly by Honeywell) reduce the power demand to within the range of a single universal thermocouple heated by a pilot (25 mV open circuit falling by half with the coil connected to a 10–12 mV, 0.2–0.25 A source, typically) by sizing the coil to be able to hold the valve open against a light ...
