All installations and services must be performed by qualified service personnel.

AFTER IGNITOR WARM-UP, THE 36E54 GAS VALVE IS ENERGIZED TO OPEN ON LOW FIRE SETTING

FLAME MUST BE DETECTED

WITHIN 4 SECONDS IF FLAME IS DETECTED, THE DELAY-TO-FAN-ON TIME BEGINS (45 SECONDS)

IF NOT

IF FLAME IS NOT DETECTED, THE GAS VALVE IS DE-ENERGIZED, THE IGNITOR IS TURNED OFF AND THE 50V61-143 CONTROL GOES INTO "RETRY" SEQUENCE

THE RETRY SEQUENCE

PROVIDES A 60 SECOND

WAIT BEFORE IGNITION

RETRY. RETRY IS

ATTEMPTED WITH A

DIFFERENT VOLTAGE

SETTING.

 

 

 

 

 

 

 

 

 

 

IF IGNITION ATTEMPT IS

 

IF SO

UNSUCCESSFUL, ONE MORE

 

 

 

 

RETRY WILL BE MADE

 

 

 

 

BEFORE THE 50V61-143

 

 

 

GOES INTO SYSTEM LOCKOUT

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

IF FLAME IS DETECTED, THEN LOST,

THE 50V61-143 WILL REPEAT THE

INITIAL IGNITION SEQUENCE FOR A

TOTAL OF TEN RECYCLES. AFTER

TEN UNSUCCESSFUL RECYCLE

ATTEMPTS, THE CONTROL WILL

GO INTO SYSTEM LOCKOUT.
