Tip & How-To about Rinnai RHFE-1004FA 38,400 BTU Energy Saver Ductless Heater - LP Gas

CHECK OUTSIDE

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.

You can cover the system as long as the vent is clear if this is a gas package unit & not a heat pump.

rinnai 431 wont start


You could have something as simple as a blocked flue pipe. Check outside and make sure the pipe is clear of ice or snow. Check the circulating fan and filter for lint. Be sure the lovers on the front of the stove are open and clean of lint.
