Startup and Checkout

OFF: Prevents main burner gas flow.
ON: Permits main burner gas flow. Under control of the

thermostat and ignition module, gas can flow to the
main burner.

NOTE: Gas controls are shipped with the gas control knob in

the ON position.

PERFORM GAS LEAK TEST

WARNING

FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY, OR DEATH

Check for gas leaks with a rich soap and water
solution anytime work is done on a gas control.

GAS LEAK TEST

1. Paint all pipe connections upstream of the gas control

with a rich soap and water solution. Bubbles indicate a gas
leak.

2. If a gas leak is detected, tighten the pipe connection.

WARNING

FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY, OR DEATH

1. Do not force the gas control knob. Use only your

hand to turn the gas knob. Never use any tools.

2. If the gas control knob will not operate by hand,

call a qualified service technician to replace the
gas control.

GAS CONTROL KNOB SETTINGS

The gas control knob operates differently in intermittent

pilot, hot surface and direct spark ignition systems.

The gas control knob settings for an intermittent pilot

system are:

OFF: Prevents pilot and main burner gas flow.
ON: Permits gas to flow into the control body. Under

control of the thermostat and intermittent pilot mod-
ule, gas can flow to the pilot and main burner.

The gas control knob settings for hot surface or direct

spark ignition systems are:
