In stock (7)

The GSK-3 detects flue gas spilling out of a draft hood or draft control and shuts down the gas burner. It opens at 180°F and stays open until someone presses the reset, so a blocked or backdrafting chimney can't go unnoticed. It works on millivolt and 24 VAC systems and mounts below a draft hood opening or along the bottom edge of an MG1 draft control (4 to 9 in.).
