• Verify supply voltage for proper polarity.
• Check external wiring for voltage feedback
• Check internal wiring for proper connections
• Check the flame sensor and verify that it is clean
• Replace DynaFlame Controller, if necessary
• Check wire connections from DynaFlame Controller to
touchscreen display
• Reset SOLA,
• If fault persists, replace SOLA
