Field Controls Pressure Switch for Power Venter

Field Controls pressure switches are replacement draft-proving switches for Field Controls power venters. They work as an airflow safety control for gas and oil-fired heating systems. The switch confirms that the venter is moving enough air before it lets the burner fire. This helps keep combustion gases moving out of the building. These OEM replacement switches suit furnaces, boilers and water heaters that use a power venter or a power venter control kit.

Key Features:

• Draft-proving safety function: senses airflow from the power venter and closes its contacts to complete the circuit to the burner only after the venter motor is up to speed.
• Burner lockout protection: if airflow is not sufficient, the switch stays open and prevents burner operation.
• OEM replacement: built by Field Controls for use with its power venters and control kits, so it can restore original system operation.
• Works with the post purge sequence: part of the control system that runs the venter after the burner shuts off to clear remaining flue gases.
• Suitable for gas and oil appliances: the product line covers the different power venter and control kit designs Field Controls offers.

Field Controls is a long-time maker of venting and draft control products for residential and light commercial heating equipment. The diaphragm of the pressure switch should be mounted in the vertical orientation shown on its label. Match the switch to your power venter or control kit model before ordering.
