The Princess, has a large 2.85cu.ft. firebox. All Blaze King catalytic stoves have a thermostat control to allow you to regulate the heat output making them usable in a wide variety of home sizes. Our deep firebox design minimizes any chance of coals rolling forward and out of the firebox when the door is opened. The distance from the door opening to the bottom of the firebox is 6 in., allowing the Princess to hold up to 60 lbs. of wood. Our deep fireboxes minimize the need to remove ashes.
