Provide electronic control of direct spark ignition systems, with external spark transformers, used on gas-fired furnaces, boilers, conversion burners and other heating appliances.
FEAturEs
• Controls ignition sequence and gas control operation in direct spark ignition systems. • Control separate 120 Vac spark generator that provides high voltage potential for main burner ignition. • Lockout after one trial for ignition if main burner fails to ignite.
• Reset from thermostat after lockout. Use separate electrodes for spark ignition and flame sensing. • Use any 24 Vac combination gas control designed for direct spark applications and rated at 2.0A or less. • For use with Natural or LP gas.

Universal Retrofit Intermittent Pilot Gas Burner Ignition Systems
Model Y8610U DEsCrIPtIon
Complete kits converting conventional standing pilot system to intermittent pilot system. For use with 24 Vac gas-fired atmospheric furnaces, boiler and heating appliances.
FEAturEs
• Y8610U kits are for use with natural or LP gas: provides 100 percent pilot gas shutoff if pilot fails to light; after 6-minute delay, trial for ignition is repeated. • Ignition trail/delay sequence is repeated until the appliance lights or call for heat is removed.
