The Field Controls 46086400 GSK-3 is a thermal safety switch designed for residential and light commercial use. This switch operates at millivolt or 24 VAC and is ideal for gas furnaces, boilers, and water heaters. It is primarily used with sidewall venting systems. The switch activates when there is flue gas spillage, ensuring the safety of the system by preventing the burner from restarting until manually reset.
This thermal safety switch efficiently detects flue gas spillage due to blocked flues or inadequate draft conditions, making it essential for maintaining safe operation.
