Ovens _,_,rithPilotless Electric Ignition: Glow Bar Ignition System (-7 Models)
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.
NORTON GLOWBAR
When the thermostat knob is turned to a
selected setting, this closes a set of electrical
contacts in the thermostat applying pow'er 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 flowing in the circuit increases in
proportion to the drop in ignitor resistance.
The NORTON ignitor limits the operating
current flow' 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 flows out of the valve and into the
burner a portion of the gas flow's across the hot
ignitor and ignition occurs.
SERIES IGNITOR/VALVE CIRCUIT
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 flame will go out.
Pressure Regulator PRESSURE REGULATOR
The pressure regulator, located on the left side of the range, at the inlet of the gas range
piping system, serves two functions.
1. Controls the flow of gas to the gas piping system. It maintains a constant pressure of
4" water column on natural gas and for LP gas, if equipped, 10" of water column.
2. Incorporates a "shut-off" valve on some models on the gas supply system. This
valve, located on the opposite side of the oven supply tube incorporates a small "lever."
When this lever is "up", no gas will flow to the oven. When "down" oven gas is on. If
the ignitor glow's and the oven won't come on, check this valve.
NOTE: Sealed burner models have a "shut-off" located at the safety valve in the rear of
the broiler area. Turn the handle on the brass valve fully clockwise to close off gas.
