Was finishing up a furnace installation and started to get strange problems.
My aux battery suddenly was down to 8V two mornings in a row.  My one pound
propane that I was using for pressure testing of new propane lines and
connections was empty as well.

I started all the usual trouble shooting for leaks and shorts and found
nothing.  Set it up again and this time checked it in the middle of the
night.  Just as I walked up to the van the furnace kicked on.

When adding a furnace and thermostat, make sure the thermostat has an off
position that is actually off.  Don�t think that putting the adjust all the
way to the bottom will work when temperatures drop to the twenties and
lower. With some testing I figure it was trying to keep my van at 30 degrees
all night with a window open.

I have now installed an on/off switch in the line.  Battery no longer
depleted and propane still in tank in the morning.
