    2. IGNITER z The Igniter plays two roles of preheating and ignition Igniter heaters. z The Heater is print-incorporated into the ceramics; therefore, it is capable of obtaining a short time of red heating of approximately 30 sec. The electric current is turned on only for preheating, while it is turned off during combustion.
