IGNITION CONTROL-Limits igniter current.
VOLTAGE LIMITER-Clamps igniter voltage to a safe level.
IGNITOR-Provides heat for lighting fuel/air mixture by glowing red-hot when energized.
FLAME DETECTOR SWITCH-Turns off ignition system once heater has started. It also connects the blower
motor directly to the +24-voIt supply so it runs at full speed. It consists of a transfer-type microswitch operated
by a ceramic rod in a closed metal tube. Heat expands the tube, moving the rod away from the switch. When
the rod moves far enough, the switch operates.
DIODE-Separates start circuit from the motor circuit. It stops the current from entering the start circuit when
heater is running.
A properly adjusted flame detector switch can prolong igniter life.
Misadjustment can cause a burned-out igniter or a heater that will not
start. information on required adjustments is contained in the individ-
ual heater component paragraphs, referenced on page 2-39 (Section
Vl. Organizational Maintenance Procedures).
