Keep Your Stove Running – Even When the Power Goes Out

Power outages happen, but that doesn’t mean you have to be left in the cold. The Model 933 Battery Backup System automatically keeps your pellet stove running when the electricity goes out.

Here’s how it works:

  • During normal power: The Model 933 keeps your battery fully charged and ready.
  • When the power fails: It instantly switches to battery power, so your stove keeps running without interruption.
  • When power returns: It automatically switches back to wall power and recharges the battery for next time.

 
You don’t have to lift a finger. The Model 933 handles everything for you. It’s reliable, automatic protection that gives you peace of mind during storms, outages, and emergencies.
