🔥 Step 1: Identify Your Fireplace Type

Start by confirming whether you have a masonry or a prefabricated (factory-built) fireplace — this determines door compatibility and safety.

Masonry Fireplace
  • Built from brick/stone; real brick firebox.
  • Typically full brick chimney.
  • Works with heavy-duty custom doors; ceramic glass optional.
Prefab (Zero-Clearance)
  • Factory-built metal firebox; metal chimney pipe.
  • Manufacturer label/tag in louver or inside frame.
  • Use model-compatible doors; tempered glass typically required.
Tip: If you see a metal ID tag or a metal chimney pipe, you have a prefab (factory-built) fireplace. If the firebox is made of brick and the chimney is full masonry, you have a masonry fireplace.
📐 Step 2: Fireplace Shape
  • Rectangular: Most common and easiest to fit (often supports stock sizes).
  • Arched: Requires a template/tracing for a perfect custom fit.
  • Multi-Sided: Corner, see-through, peninsula need custom engineered solutions.

📏 Step 3: Measure Correctly
  1. Measure width at top, middle, bottom — use the smallest.
  2. Measure height at both sides (and center if arched) — use the shortest.
  3. Identify the lintel bar (steel support at top of masonry). Measure to the bottom of the lintel.
  4. Compute United Inches: width + height (helps with pricing brackets).
  5. Check diagonals for out-of-square openings.

⚒️ Step 4: Installation Fit
  • Overlap (Face-Mount): Frame overlaps the opening; hides gaps; ideal for masonry; forgiving on imperfect openings.
  • Inside Fit (Flush-Mount): Frame sits inside the opening; sleek; requires precise, square measurements; often used for prefabs.
  • Special Case: Hole-in-wall (no hearth) usually needs a 4-sided overlap frame with a bottom piece.

🚪 Step 5: Door Styles
Cabinet Doors

Two panels swinging left/right. Clean look; widest opening when fully open.

Bi-Fold Doors

Panels fold to reduce clearance; choose trackless (fold flat) or tracked (guided).

Sliding

Modern, custom track systems. Less common; used for specific designs.

🪟 Step 6: Glass, Materials & Finish
  • Glass: Tempered (standard; typical for prefab) or Ceramic (high-heat; suitable for burning with doors closed on masonry).
  • Frame: Steel (robust, ideal for high heat) or Aluminum (lightweight; common on prefab replacements).
  • Finishes: Powder-coat matte black, bronze, graphite, or premium plated/brushed metals.
  • Glass Looks: Clear for maximum view; gray/bronze tint to reduce glare; mirrored/black to conceal firebox when off.
🧵 Step 7: Mesh & Accessories
  • Mesh Curtain: Slides on a rod; simple spark protection when glass is open.
  • Mesh Doors (Gate): Hinged steel mesh panels; premium look and easy operation.
  • Hardware: Handle styles, magnetic catches, optional child-safe locks.
If you burn wood with the glass open, use a mesh barrier for safety and ember control.
🛒 Step 8: Order & Installation
  1. Choose custom (perfect fit, more options) or stock (faster, budget-friendly).
  2. For prefab: confirm model compatibility; don’t cover vents.
  3. Upload photos for expert review; verify narrowest measurements.
  4. Expect a few weeks for custom production; stock ships faster.
  5. Install with included hardware, or hire a pro for heavy/complex sets.
