Caution on startup procedure, do NOT put power to the heater until after the pump has run a good 20

minutes or more so all air is out of the system. In other words, DO NOT TURN UP THE TEMPERATURE

until you run the pump 20 minutes minimum, AND INSURE ALL AIR IS OUT OF THE PIPING. Failure to

follow this important procedure runs the risk of dry-firing the element, and BURNING IT UP.
