New topic for newbies: Furnace know how
So were were discussing the furnace while we ordered our generator and my son says: So I get you running the furnace on LP but if you're not hooked up isn't there a fan or something that runs the furn...

My furnace fan draws about 8 amps DC (from the batteries).
This is roughly 0.8 amps (round up to 1 amp) AC needed from your generator to run the converter (charger). Nothing to worry about especially if you sized your generator to run the air conditioner. However, to minimize the generator run time necessary to recharge your batteries, you will want a good converter (charger), along with correctly sized wire, to charge the batteries at close to maximum capacity.
When the generator isn't on, your batteries will provide the power to run the furnace fan. If you figure on using up 50% of the capacity of one battery (maximum recommended draw for most batteries) per night in cold weather, you will be pretty close. So two batteries (doesn't matter if they are 6 or 12 volts) will last you about two nights (4 batteries = 4 nights, etc.).
There is a lot more to it, but this should get you in the ballpark.
