GrandSeal Fireplace Doors with Ceramic Glass
The Grand Seal Fireplace Door is expertly designed to eliminate back smoking in fireplaces operating under negative pressure levels up to -25 PA. This innovative enclosure allows you to enjoy the warmth and ambiance of a traditional wood-burning fireplace, even in areas with the most demanding energy efficiency codes. As one of the highest-performing ceramic glass fireplace doors available, it features gasketed swing sections that fully encase each glass panel, ensuring a tight seal. The frame is also gasketed to the face of the fireplace, reducing heat loss and improving efficiency. These premium ceramic fireplace doors provide exceptional durability, safety, and performance - making them the perfect fireplace doors with ceramic glass for modern, energy-conscious homes.
A sealed fireplace door features high-temperature, continuous woven gaskets that tightly seal the frame, operable doors, and glass panels to effectively block air movement into or out of the firebox. By eliminating air leakage and cold drafts, these doors enhance fire control, minimize lingering fireplace odors when not in use, and improve household energy efficiency by stabilizing indoor temperatures. Additionally, sealed doors prevent back smoking even under extreme negative pressure exceeding -25 PA, making them an ideal, code-compliant solution for wood-burning fireplaces in regions with strict building regulations.

Recommendations:
- Overlap: Each door will be built to overlap the masonry opening by one inch on the sides and top unless specified differently.
- Accurate Measurements: Your custom-built door will be as accurate as the measurements provided. Use a rigid tape or metal ruler for exact measurements.
- Mounting Flange: A mounting flange will protrude into your fireplace opening 2 inches, sized to allow a 1/4” space between it and your masonry opening. This area is used to pack fiberglass insulation to seal the frame to the masonry face. Holes must be site-drilled through this flange into the masonry for attachment.
- Caulking: Use high-temperature silicone or refractory caulking to fill any voids between the door frame and your fireplace.

Stove Bright Color Chart:
1. The tools required for installation: a power drill, a 1/4" metal drill bit, a 3/16" masonry drill bit, a 5/16" socket with ratchet, a caulking gun, hi-temp silicone and safety glasses. Always wear safety glasses during installation to prevent unwanted objects in your eyes. Use properly grounded electrical cords to prevent electrical shock.
2. The door installation kit includes: an insulation strip, self tapping masonry lag screws and 2-wooden handles.
3. Remove all parts and protective packing from the door carton.
4. WARNING! This door frame must be installed PLUMB!! DO NOT FORCE THE DOOR TO FIT IRREGULAR OPENINGS!! This will cause misalignment of the glass sections and a poor seal will result. Plumb the masonry front with cement or fill the void with insulation. All doors are factory fit on a plumb surface to verify alignment and fit of the doors.
5. Measure the sides of the opening to determine where cement joints exist. Drill the builders flange using the 1/4" metal drill bit at the appropriate joint heights and in ½ inch from the back side of the builders flange. Usually, the lowest holes are up approximately 8" from the hearth line. Drill the top holes approximately 2" down from the lintel iron. See the illustration on the back of this page. Place the door frame into the opening and mark the cement seams where the holes have been made in the builders flange. Remove the frame and drill holes into these marked areas with the 3/16" masonry bit. These holes must extend in as deep as the lag screws.
6. Reposition the frame into the opening and start the masonry lags in the holes. Set the door frame in the opening and center left to right. Insert the fiberglass seal between masonry and the builders flange. Tighten the screws into the masonry cement using the 5/16" socket and ratchet. Verify that the door frame is plumb. Place the doors on the hinges and re-plumb if doors are out of alignment. Tighten all mounting screws evenly.
7. Use Hi-temp silicone to seal the inner perimeter of the builders flange to the fireplace facing for maximum sealing, avoiding contact with the outside finished front of doors and frame.
8. If a bottom mounted block wood handle is used, place several drops of crazy glue in the handle hole to permanently attach the wood handle to the door latch. The flat non-milled side of handle goes toward the door. Glue contacting the door or frame finish may discolor this finish.
