  • Fireplace door installation requires power tools. You will need a pencil, 1/16” Drill Bit, Power Drill, and a Phillips head Screwdriver.
  • Place new door carefully into fireplace opening and use the pencil to mark hole location through inside of the door frame.
  • Remove door from opening and use the power drill and 1/16” drill bit to drill holes through the sheet metal of the metal firebox.
  • Place door back into fireplace opening and use screws and screwdriver to finish installation. DON'T forget to peel off protective plastic.
  • Self tapping screws are provided and eliminates the need for pre-drilling. Be careful when using a power drill, to avoid slipping off the screw heads and damaging the fireplace door!

PLEASE NOTE: MESH SPARK PROTECTION IS NOT INCLUDED WITH THIS PRODUCT! Our pictures show factory-installed mesh that came with the zero clearance fireplace.
