Robertshaw 712-017 Pilot Ignitor System

The uni-line 712 series pilot ignition system features flame rectification with solid-state logic and flame sensing to provide automatic sequencing that will ensure proper operation of an intermittent pilot ignition device. The 712 series pilot ignition system features quick and easy installation with complete in-depth instructions and trouble shooting information. The 712 pilot ignition systems are available with one of four different gas valve types to fit a wide range of furnace applications. Depending on the model of gas valve used, 712 systems are available to handle applications up to 720,000 btu (natural gas). see ordering chart for the exact specifications of each 712 series pilot ignition system. The Sp845 lockout ignition control used in the 712 lockout uni-kits, provides 90 seconds of spark followed by a six minute time delay (purge) period between ignition attempts. After three tries, if no pilot flame is sensed, Sp845 goes into a 1 hour lockout period. At the end of the 1 hour lockout period, if the demand for heat is still present, unit repeats the three tries for ignition.
