Tip & How-To about Rinnai RHFE-1004FA 38,400 BTU Energy Saver Ductless Heater - LP Gas
Make sure your outside vent is not snow or ice covered. My heater kept flashing #12 and I went to check this first. There was no snow or ice directly on the vent, HOWEVER, there was a snow bank about 1/2 foot IN FRONT of the vent. I shoveled the bank to below the vent level providing more clearing; even though it wasnt touching the vent, this made my heater work again.
