PERFORM GAS LEAK TEST
WARNING:
Stand away from the main burner while lighting.
Hidden gas leaks can cause flashbacks in the appliance area. Check for gas leaks with rich
soap and water solution any time work is done on a gas system.
GAS LEAK TEST
- Using a solution of soapy water, paint the piping connections which are upstream of the control.
The presence of bubbles indicate a gas leak is present.
- If a leak is detected, tighten the pipe connections and repeat leak test.
- Light the main burner.
- With the main burner in operation, paint all piping connections from the valve with a soap and
water solution.
- If another leak is detected, tighten the connection.
- If after tightening the connections the leak is still present, replace the leaky part and, or valve.
Shut off the main gas supply before attempting replacement of parts or the valve.
- Using the soap and water solution test, the pressure test ports and min rate screw to verify that
no leak is present.
- If a leak is detected tighten the screw and retest.
- If after tightening the pressure test port or min rate screw the leak is still present, shut off main
gas supply and replace the valve.
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 the appliance in operation. The pilot and main burners should be 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.
