ACV Burner control 537D8185

The ACV 537D8185 is a burner control box for gas or oil burners, designated BG2000s V13. It manages the ignition and safety sequence, including pre-purge, ignition transformer energization, fuel valve opening, flame monitoring, and lockout if flame is not detected within the safety time. It also reads signals from air and gas pressure switches and responds to thermostat or controller heat demand. This unit is compatible with ACV BG2000s V13, HeatMaster 71 TC, and Smart 210 models.

Parts of this type are selected by matching the exact series and type designation, supply voltage, and programmed safety and pre-purge times. The flame detection method (ionisation for gas, UV or IR for oil) must also correspond. Verify the unit against the burner's original specification before installation, as controls are not interchangeable across series even within the same brand.

When a control box of this kind fails, the burner may not start, lock out repeatedly, or shut down during operation. Common issues include failure to detect flame, faulty pressure switch readings, or internal component failure. Check for error codes, verify power supply, and test the flame sensor and pressure switches before replacing the control.
