PILOT (On standing pilot controls only): Permits
pilot burner gas flow when red knob is held down or
thermocouple current is above power unit dropout
value.
ON: Permits gas flow into gas control. Pilot burner gas
is controlled as in the PILOT position for standing pilot
and intermittent pilot systems. Main burner gas flow
is controlled by thermostat and automatic valve
operators.
Perform Gas Leak Test
WARNING
Fire or Explosion Hazard.
Can cause property damage, serious injury
or death.
Check for gas leaks with soap and water solution
any time work is done on a gas system.
Gas Leak Test
1. Paint pipe connections upstream of gas control
with rich soap and water solution. Bubbles indicate
gas leak.
2. If gas leak is detected, tighten all pipe connections.
3. Stand clear of main burner while lighting to prevent
injury caused from hidden leaks that could cause
flashback in the appliance vestibule. Light main
burner.
4. With main burner operating, paint pipe joints
(including adapters) and control inlet and outlet
with rich soap and water solution.
5. If another gas leak is detected, tighten adapter
screws, joints, and pipe connections.
6. Replace part if gas leak can not be stopped.
Light Pilot (Standing Pilot Models)
1. Turn gas control knob clockwise
Wait five minutes to dissipate any unburned gas.
Smell for gas around the appliance near the floor.
Do not relight pilot flame if you smell gas.
2. Turn gas control knob counterclockwise
PILOT. Push down and hold the knob while lighting
the pilot flame.
3. Hold down the gas control knob about one minute,
then release.
a. If pilot flame goes out, turn gas control
knob clockwise
1 through 3.
b. If pilot flame remains lit, turn gas control
knob counterclockwise
Turn on System (Intermittent and
Direct Ignition Systems)
Rotate the gas control knob counterclockwise
ON or slide gas control switch to ON.
Turn on Main Burner
Follow appliance manufacturer instructions or adjust
thermostat setting to call for heat.
Adjust Pilot Flame
The pilot flame should envelop 3/8 to 1/2 in.
(10 to 13 mm) of the thermocouple or igniter-sensor tip.
