check plus valve on delay before ignition.
• Available with 4 or 11 second (nominal) lockout timing.
• 100 percent shutoff for use with all heating gases.
• Ambient temperature rating is -40°F to +175°F (-40°C to
+80°C).
• Separate electrodes for spark ignition and flame
sensing.
• Uses Honeywell or any other 2A or less dual valve
combination gas control designed for Direct Spark
