Fireplace doors · Start with the right type

Brick outside.
But what is inside?

A brick or stone surround can hide either type of fireplace. Look at the firebox, then find its label before choosing doors.

The finished surround shows the style. The firebox and its model details tell us which doors to consider.

01 · Look inside a cold fireplace

Compare construction, not decoration.

Look at the inside walls and opening edges. Illustration of one construction, not a test of every fireplace.

Masonry fireplace

A site-built firebox is usually made from firebrick and mortar. Individual bricks and joints can be visible on the inside walls. A metal lintel may support the opening at the top.

Useful evidence: clear views of the inside walls, opening edges and hearth, plus any construction records.

What does not prove it: the stone mantel, a brick chimney seen from outside, or the age of the house alone.

Factory-built metal firebox with refractory panels
Compare the metal body and interior panels. Panel patterns and vents vary by model.

Factory-built / prefab fireplace

A manufactured firebox has a metal body. Its interior may have refractory panels with a brick pattern, so a brick-looking interior can still be prefab. Some units have vents or louvers around the opening.

Useful evidence: the fireplace manufacturer, exact model number, and the matching manual.

What does not prove it: a metal part by itself. Some masonry fireplaces contain metal components too.

These cutaway illustrations show the difference in construction. A finished wall can hide either system; use the fireplace model or construction evidence to confirm yours.

Already behind sealed glass? If the glass is part of a gas fireplace or insert, start with that appliance’s model and approved front. Decorative doors for an open fireplace are not a substitute for its sealed glass or safety barrier.

02 · Find the most useful detail

A model number is better than a guess.

What to photograph: the manufacturer and full model number, plus the whole label. This is an illustrative label with example numbers, not a product certificate.

  1. Let the fireplace cool completely

    Use your phone light to look for a rating plate or label near the opening or in an accessible area described in the manual. Label locations vary. Do not remove sealed glass, fixed panels, gas parts or electrical covers to search.

  2. Photograph the whole label

    We need the brand and complete model, including letters and suffixes. A close-up of the whole label is more useful than a cropped serial number. Keep a second photo showing where the label sits.

  3. Check whose label it is

    The name on the old door, gas-log burner or remote may be different from the fireplace manufacturer. Tell us what the label is attached to. If you have the fireplace manual, send its cover or exact model listing.

I cannot find a label

That does not make the fireplace masonry. Send the full opening, inside sidewalls, top edge and hearth in clear photos. Leave the fireplace type as “not sure” until we review the evidence.

03 · A useful next step

Choose the description closest to yours.

I have a fireplace brand and model

Start with prefab options if the manual identifies a factory-built fireplace. Ask us to check the exact door against that model, its mounting points and required airflow. Matching opening dimensions alone is not enough.

I can see built-in brickwork, but have no model

Masonry is a possible starting point. Photograph the inside construction and measure the opening. Our specialists can review it before you choose a mounting style.

There is fixed glass, a sealed insert, or controls

Find the appliance model first. The correct replacement may be an approved glass assembly, screen or decorative front rather than a custom door for an open firebox.

Help me find the right part
I am still not sure

Use “Check my fireplace” on our door collection to share a photo, or schedule a call. You can explore styles while we sort out the construction; a photo suggestion is a starting point, not a final fit selection.

Open the fireplace photo check

Let us look at it with you.

Bring a photo of the whole fireplace, close-ups of the inside and opening edges, any model label, and the style you like. We can tell you what information is still needed before you order.

Why the type matters

Different fireplaces require different doors. The Hearth Craft Essentials manufacturer manual, for example, limits those doors to masonry fireplaces and directs owners of factory-built fireplaces to check their make and model. Always use the instructions for the actual fireplace and door you select.
