GAS CONTROL KNOB
Gas control knob settings are as follows:
OFF prevents pilot and main burner gas flow from
passing through valve.
PILOT permits pilot gas flow only. Gas control knob
must be held depressed
must
be heated sufficiently to hold the Pilotstat safety control
valve open.
ON permits pilot or main burner gas flow into gas control
body. Under control of thermostat and ignition module, gas
can flow to pilot and main burners.
PERFORM GAS LEAK TEST
FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE, SEVERE
INJURY, OR DEATH
Check for gas leaks with soap and water solution
any time work is done on a gas module.
GAS LEAK TEST:
1. Paint pipe connections upstream of gas control with
rich soap and water solution. Bubbles indicate gas leak.
2. If leak is detected, tighten pipe connections.
3. Stand clear of main burner while lighting to prevent
injury caused from hidden leaks which could cause flash-
back in the appliance vestibule. Light main burner.
4. With main burner in operation, paint pipe joints (in-
cluding adapters) and control inlet and outlet with rich soap
and water solution.
5. If another leak is detected, tighten adapter screws,
joints, and pipe connections.
6. Replace part if leak can’t be stopped.
