My new RHFE-1004FA has a slight whistle to it
Went to camp today to start the furnace for the winter. When I fired it up it seems to have a slight whistle that is intermediate. It didn't do that this fall when I installed it. I did add a propane tank. Is it possible it has air in the line? If so how do I purge it?

May have a bad regulator on the tank or bad gas pressure. The colder it is, the less gas pressure you get out of the tank.
