HE Series Infrared Gas Heater Installation and Operation Manual
The step-up transformer in the ignition control provides spark ignition at 30,000 volts (open cir-
cuit). To check the spark ignition circuit, proceed as follows.
• Shut off gas supply to the gas control
• Disconnect the ignition cable at the ignition control stud terminal to isolate the circuit from
the Spark Igniter or Igniter / Sensor
• Prepare a short jumper lead, using heavily insulated wire such as ignition cable
• Perform this test immediately upon energizing the system before the Ignition Control goes
into safety lockout and interrupts the spark circuit. Touch one end of the jumper firmly to the
ignition control GND terminal. (DO NOT remove the existing ground lead.) Slowly move the
other end of the jumper wire toward the stud terminal on the Ignition Control to establish a
spark.
• Pull the wire away from the stud and note the length of gap at which spark discontinues.
• A spark length of 1/8 in. (3 mm) or more indicates satisfactory voltage output. If no arc can
be established, or the maximum spark is less than 1/8 in. (3 mm), and power to the Ignition
Control input terminals was proved, replace the Ignition Control.
Use the following diagram to check the Igniter gap. If the gap is incorrect all adjustments
should be made with the
