| The safety valve contains a small heater and a bimetal connected directly to the gas valve. (see figure 6-J) When enough voltage is applied as described in section 6-4, the heater heats the bimetal, which opens the valve. When the oven thermostat senses the right oven temperature, it cuts off the power to the ignitor and gas valve, and the bimetal cools and shuts off the gas flow. | ||||||||||
| There are two different types of ignitors in common use, round (aka carborundum) and flat (aka square, or Norton-type.) (see figure 6-K) Their resistances are different, so the gas safety valve that each uses is different, but the principle is the same. | ||||||||||
