Manual Reset
Thermostat
A manual reset thermostat (1) comprising a high-temperature cutout
with a built-in reset switch is located on the lower portion of the heater
housing. Its purpose is to backup the temperature sensors of the
heater control system. In a situation where the heat exchanger
overheated and the heater controller did not shut down the heater, this
manual reset thermostat would activate and cut off all electrical power
to the heater, thus causing the heater to shut down; Once the heater is
determined to be safe for operation, the manual reset thermostat
must be reset by pushing the reset switch button located
underneath the rubber protector that is located on the heat exchanger
end of the heater.
