 Troubleshooting Sequence.

START

•  TURN OFF GAS SUPPLY
•  ASSURE SmartValve SWITCH IS IN ON POSITION
•  DISCONNECT SYSTEM CONTROL HARNESS
•  SET THERMOSTAT TO CALL FOR HEAT

CHECK FOR PROPER VOLTAGE AT CONTROL 
HARNESS (SEE INSET A). VOLTAGE SHOULD BE 
24V BETWEEN THERMOSTAT OR PRESSURE 
SWITCH AND 24V COMMON, AND 24V 
BETWEEN 24V COMMON AND 24V HOT.

CHECK:
•   LINE VOLTAGE POWER
•   LOW VOLTAGE TRANSFORMER
•   LIMIT CONTROLLER
•   THERMOSTAT
•   WIRING
•   AIR PROVING SWITCH ON COMBUSTION AIR 
    BLOWER SYSTEM
•   VENT DAMPER (IF USED) IS OPEN AND END 
    SWITCH MAKES

PLUG HARNESS INTO SmartValve  CONTROL. 
WAIT FOR INTERNAL CHECK DELAY (SV9501/SV9601) 
OR PREPURGE (SV9502/SV9602)

IGNITER WARMS UP AND GLOWS RED

•  TURN ON GAS SUPPLY
•  PILOT BURNER LIGHTS

MAIN VALVE OPENS AND MAIN BURNER LIGHTS

REPLACE IGNITER/FLAME ROD ASSEMBLY

CHECK THAT PILOT GAS IS FLOWING.  WAIT TO 
ASSURE PILOT GAS TUBING IS PURGED.  RECYCLE 
CALL FOR HEAT IF NECESSARY.

MEASURE VOLTAGE BETWEEN 24V HOT AND 24V 
COMMON LEADS TO SmartValve CONTROL.  MUST 
MEASURE AT LEAST 19.5 VAC WITH IGNITER 
POWERED.  SEE INSET A TO IDENTIFY PROPER LEAD.  
THIS CHECK MUST BE DONE WITH THE SmartValve 
CONTROL CONNECTED AND IGNITER POWERED.

•   CHECK THAT PILOT FLAME MAKES GOOD 
    CONTACT WITH PILOT BURNER FLAME ROD.
•   CHECK FOR GOOD ELECTRICAL CONNECTION 
    THROUGH THE PILOT TUBING.
•   IF BOTH OF THE ABOVE ARE GOOD, REPLACE 
    IGNITER/FLAME ROD ASSEMBLY
