    Safety Precautions WARNING This device does not have a prepurge function. Use this device as part of a system whose design gives careful consideration to the prepurge timer and ignition sequence timing, following established safety guidelines. Connect loads (ignition transformer, solenoid valve, etc.) directly to the output terminals of this device.
  • Page 5 WARNING When the pilot turndown test is complete, turn OFF the power switch to shut down the power. Restore all test jumpers and limit interlock/regulator settings to their previous states. If operation begins without the above steps, damage to the equipment, gas leak or explosion may result.
  • Page 6 CAUTION Make sure the load connected to each terminal does not exceed the rating indicated in the specifications. If timers and auxiliary relays are needed for additional functions, select ones with high reliability, and be sure to design the circuit correctly. When installing and wiring, be sure to follow the instructions in this manual and in the user's manual for the combustion equipment.
  • Page 7 CAUTION When cleaning the burner, clean the flame detector as well. For transportation or storage of this device, remove it from the subbase and pack it in its original box. It might be damaged if transported while mounted on a panel or the like. Do not short the control load terminals (18-19, 18-20, 18-21, or 18-22) or the shutter terminals (7-8).
