anode rod is a maintenance item that you should plan on replacing annually.

Water Heater 12 Volt / Propane Operation
Turning the 12 Volt Water Heater switch ON should start the propane side of the heater as long as
propane is flowing and your batteries/power converter are providing approximately 12V DC.
Once the switch is turned ON, a small indicator light will illuminate for about 15 seconds to let you know
that the ignition sequence is underway. When the burner is lit, the light will go out. During the 15
seconds, the control board will attempt to purge air from the propane feed line and will attempt to light
the propane burner 3 times. If it fails, the water heater will lock the LP operation for safety reasons and
the light will stay on. To clear the lockout, turn the switch off for 10 seconds and then turn on again to
retry. Note that if the water in the tank is already heated, the ignition sequence may not occur until the
water cools a bit.
Yeti Package - Tank Heaters and Heat Tape
The optional YETI package includes 120V AC powered tank heating pads on each holding tank along with
12V DC powered heat tape on the portion of the fresh water feed line in the underbelly. One switch
turns on all the tank heating pads. The other switch turns on the heat tape so that the water line from
fresh tank to the pump doesn’t freeze.
