Slight problem this morning!
8:00 am Christmas morning my Dad calls and his propane furnace and stove aren't working! I go over and he is at 45% in his tank,looking at the regulator mounted to the side of the house I noticed it was caked in ice from water dripping from the eaves and freezing on it. A bucket of lukewarm water and a slight tap (not sure if it helped but it made me feel better!) and everything was set to go. I believe the ice was frozen around the vent/breather on the bottom of the regulator. Do you think this was the problem rather than the ice on the rest of it?
Looks like I will have to fashion a hood/overhang to fit over it.

Probably was just clogging the vent.

Make that cover SOON! Clogging that vent can cause the regulator to develop excess pressure and overfire the furnace and has caused explosions on natural gas systems. The excess pressure can blow the gas valve.

Around here, there are about 2 or 3 house fires/explosions each year caused by an ice covered regulator. It's far more hazardous than you might think.

City gas main pressure can go up to 60 psi. Gas valve rated for 1/2psi. House go BOOM BOOM. Gas co. guy told me of such a story where I am. Scary stuff!!

Got my buddy making a cover! On the LP tank there is one regulator and then another at the entrance to the house. Are they just set at different psi?

The primary, brings the pressure down to 10 PSIG.
The secondary/house regulator lowers the 10 PSIG to 11.5" or so.
