Description

A McDonnell & Miller #67 low water cut-off, a long-standing standard on steam boilers. It shuts the burner down if the water level falls below a safe point, preventing the dry firing that cracks sections and destroys a boiler. It mounts into the boiler at the correct level, so the tapping and mounting arrangement have to match the boiler as well as the electrical rating — check both when replacing an existing unit.
