• SECTION 11: Operation and Maintenance
  • 11.1 Sequence of Operation
    • 1. Turn the thermostat up. When the thermostat calls for heat, the SmartValve® II will energize. After a short period, power is supplied to the blower motor.
    • 2. When the motor approaches nominal running RPM, the pressure switch closes and signals the ignition module/SmartValve® II.
    • 3. The ignition module/SmartValve® II then energizes the hot-surface igniter for a timed warm-up period (approximately 45 to 60 seconds). After the warm-up period, the gas valve is energized.
    • 4. If a flame is detected, the gas valve remains open and the igniter is de-energized. When the call for heat is satisfied and the system control mechanism de-energizes the burner line voltage supply, the gas is turned off.
    • 5. If no flame is detected by the flame sensing rod, the igniter is de-energized and the module/ SmartValve® II will close and a purge period begins. After the purge, the module/SmartValve® II acts to power the igniter for a second warm-up period a...
    • 6. If the flame extinguishes during operation, the igniter module will provide multiple trial sequences described in step 5. If ignition is not re-established, the module/SmartValve® II will lockout for one hour or until reset.
    • 7. After lockout, reset by turning down thermostat for five seconds, and then raising it again to desired temperature, or by disconnecting power and then reconnecting.
