|
A.Check ignition cable ground wiring, ceramic insulator and gap. Correct if necessary.
B.Does ignition cable show signs of melting or buckling? Take protective action to shield cable and boot from excessive temperatures.
| A. Are all manual gas valves open? | |
NO | Are supply tubing and pressure good? | |
Are pilot burner orifices blocked? | ||
|
B.Check electrical connections between module and pilot operator on gas control.
C.Check for 24VAC across
If voltage is not correct, replace module.
|
| NOTE: If module goes into lockout, reset system. | |
NO | A. Check continuity of ignition cable and ground wire. | ||
B. Clean flame rod. | |||
|
| ||
|
| C. Check electrical connections between flame rod and | |
|
| module. | |
|
| D. Is ceramic flame rod insulator cracked? | |
|
| E. Is pilot flame a steady blue? Does flame cover flame rod? | |
|
| If not, adjust pilot flame. Replace module if problem | |
|
| persists. | |

A.Check for 24VAC across
NO | B. Are electrical connections between module and gas | |
control good? | ||
| ||
| If connections are good, replace gas control or gas | |
| control operator. |
| NOTE: If module goes into lockout, reset system. | |
| ||
| A. Check continuity of ignition cable and ground wire. | |
NO | NOTE: If ground is poor or erratic, shutdown may | |
occasionally occur even though operation is normal | ||
| ||
| at time of checkout. | |
|
B.Is pilot flame a steady blue? Does flame cover flame rod? If above checks out, replace module.
