System Operation
The glow-bar ignition system consists of three
main components:
1. The thermostat (or range control).
2. The glow-bar ignitor.
3. The oven gas valve (also called the safety
valve).
The thermostat, ignitor and gas valve are wired
in series.
When the thermostat knob is turned to a
selected setting, this closes a set of electrical
contacts in the thermostat applying power to the
series circuit.
With power applied, the ignitor begins to heat.
The electrical resistance of the ignitor will
decrease as the surface temperature of the
ignitor increases.
Current owing in the circuit increases in
proportion to the drop in ignitor resistance.
The NORTON ignitor limits the operating
current ow in the circuit to 3.3 to 3.6 amps.
When the current has risen high enough to open
the valve, the surface temperature of the ignitor
is between 1800 to 2500 degrees F.
As gas ows out of the valve and into the
burner a portion of the gas ows across the hot
igniter and ignition occurs.
The ignitor will remain energized when the
burner is lit. Once the oven reaches the selected
temperature, the thermostat contacts will open
and remove power from the ignitor/valve
circuit. The valve will then close after a few
seconds and the burner ame will go out.

Oven with Pilotless Electric Ignition: Glow Bar Ignition System (-7 Models)
Models with glow bar oven ignition have a manual shut-off valve located at the
safety valve in the rear of the broiler area. To access this valve, remove the broiler
pan and boiler rack. Turn the handle on the valve fully clockwise to close off gas.
If the ignitor glows and the oven won't come on, check this valve.
