As Ron said, the furnace will work with your 12volt system.
As for how long those two batteries last depends on the following:
- What kind of battery and how big (In amp-hours such as the 20hr rate)?
- How long does the furnace need to run?
- What are your other power needs during the period?
That info will help estimate for you.
Also, keep in mind that you do not want to discharge your batteries under 50% SOC before fully recharging. So, you basically have half the capacity you think you do.
Here's a nicely written primer on everything 12 volt.
