Are there any safety issues concerning the door and feeding the fire?

Opening Your Furnace Door

• Your furnace is equipped a double latch safety system and 18″ handle. When opening the door the latches will “catch” before completely opening.
• If you burn only approved materials, you should never have any “blow back” when you open the door.
• It is unlikely in the Earth Furnace to ever have “blow back”… but it is always wise and prudent on any type of furnace to be aware of any potential and use reasonable care when opening.
• Always keep your facial area away from or close to the door area. That fire is hot! Sometimes a rush of air on a simmering furnace can cause pretty quick combustion. Always use caution.
