SHUTDOWN PERFORMANCE TEST
WARNING:
Fire or Explosion Hazard.
Can cause severe injury or death.
Perform the safety shutdown check any time work is done on a gas system.
1. Place appliance in operation with the pilot and main burners lit.
2. Place gas control knob in “PILOT” position. Main burner should extinguish and pilot should
remain lit.
3. Extinguish pilot flame. Pilot gas safety shutoff proves complete shutdown due to the fact the
safety shutoff valve prohibits main burner and pilot gas flow.
4. Wait at least five minutes for the safety magnet to reset and residual gas to clear from the
combustion chamber.
5. Relight pilot burner and operate the system through one complete cycle to ensure all functions
operate correctly.
