I highly doubt it. I don't think it would last that long. You need some combustion air and a good draft, the draft of a chimney may be enough to get it thru short durations (20-40 mins) and come back burning.
From the Brochure. So, Maybe....
Harman sites states "Now offering Battery Backup option."
If it did, I don't think any of us would be talking about UPS units for our stoves.
Also, If you have a power vent or direct vent, forget it. The stove will go out after a short period (30+ mins).
