Installation of a High temperature vent limit switch is recommended for LP and Natural gas fired power vented and natural draft water heaters. This device is installed to limit the vent temperature in either plastic pipe (1400 F temperature limit) or B vent installations (5500 F temperature limit) caused by scaled up tanks and/or inadequate venting. Wiring MUST be in accordance with the National Electrical Code and applicable local codes.
