All Espar heaters low and high voltage controls that will shut the heater off if voltage is below 10.5V and above 15 volts. Make sure you have 12 volts AT THE HEATER during startup of the heater.

One of the most important preventative maintenance procedure to be performed is running the heater once a month for about 20 minutes, every month.
