(393691) and 3.5 in. wc (0.9 kPa) for natural gas
regulator (394588).

START-UP
Gas Control Knob Settings
OFF: Prevents pilot and main burner gas flow.
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 stand-
ing 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 severe injury, death or property
damage.
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 indi-
cate gas leak.
2.
If gas leak is detected, tighten all pipe connec-
tions.
3.
Stand clear of main burner while lighting to pre-
vent 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
to OFF.
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
to PILOT. Push down and hold the knob while
lighting the pilot flame.
3.
Hold down the gas control knob about one min-
ute, then release.
a. If pilot flame goes out, turn gas control knob
clockwise
to
OFF
and repeat steps 1
through 3.
b. If pilot flame remains lit, turn gas control
knob counterclockwise
to ON.
Turn on System (Intermittent and
Direct Ignition Systems)
Rotate the gas control knob counterclockwise
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. Refer
to Fig. 3. To adjust pilot flame:
1.
Remove pilot adjustment cap screw. Refer to
Fig. 1.
2.
Turn inner adjustment screw clockwise
to
decrease or counterclockwise
to increase
pilot flame.
3.
Always replace cap screw after adjustment and
tighten firmly to safeguard proper operation.
