Fenwal Triton Ignition Control Kit
This kit enables the Fenwal “Triton” local sense, one-hour retry, direct
spark ignition (DSI) control to be used as a service parts replacement for
earlier versions of Fenwal DSI controls used on HW/HWC models.
The operation and features of this ignition control differ from the other
types of DSI controls used. These features include:
• Longer trial for ignition (15 seconds nominal).
• One-hour retry feature (if main burner operation is not proved after
three trials for ignition, control goes into lockout for one hour, then
automatically initiates another ignition sequence; will repeat as long
as call for heat exists).
• Senses flame through spark electrode (local flame sense) instead of
through a separate flame sensor (remote flame sense).
• Diagnostic LED indicates certain ignition and venting system mal-
functions (refer to control label for specific diagnostic codes).
• Includes flame current (FC) test terminals.
