Temco TLC36 Fireplace Doors — Custom Exact-Fit Replacement
Replacement Doors for the Temco TLC36 Fireplace
The Temco TLC36 is a 36-inch, louvered, heat-circulating wood-burning fireplace built by Temco Fireplace Products from the 1980s into the 1990s. Temco is long gone as a standalone company — its hearth lines were eventually folded into what is now Innovative Hearth Products (IHP) — but hundreds of thousands of these fireboxes are still in living rooms across the country, usually with a rusted screen and no doors at all. If yours is one of them, this page is for you.
First, confirm what you have. Every TLC36 carries a metal rating plate inside the firebox — typically riveted to a side wall of the smoke shield area, or visible when you look up behind the top edge of the opening. On louvered models like this one, it may also sit just behind the lower louver grille below the opening. Shine a flashlight and look for the model number. You may see TLC36-2, TLC36-3, TLC36-2I, or TLC36-3I — all revisions of the same 36-inch louvered circulating firebox, and all take the same style of door. Close cousins in the TFC36 series share the front frame design as well. If the plate is unreadable, don't worry: a photo of the fireplace front is enough for us to identify it.
Why You Can't Buy the Original Doors Anymore
Temco stopped producing this fireplace decades ago, and OEM door kits dried up with it. What's left in the parts channel is a shrinking pile of new-old-stock and "Temco-style" generics, and most listed accessories for the TLC36 are already marked discontinued by parts houses.
The tempting shortcut — a universal or masonry fireplace door from a big-box store — doesn't work here, for three concrete reasons:
- Prefab fireplaces need an inside-fit door. The TLC36 is a zero-clearance, factory-built unit with a sheet-metal face. Masonry doors are overlap-fit: they clamp to flat brick around the opening. On a prefab face there's nothing safe to clamp to, and covering the louvers or face vents can overheat the chase.
- The fit must be exact. A prefab door mounts inside the opening against the firebox flange. A quarter inch off and it either won't seat or leaves gaps that defeat the purpose of the door.
- Safety listing matters. The TLC36 series was listed under UL 127 as a complete system. A door designed for prefab fireboxes — tempered safety glass, correct frame depth, no blocked airflow — keeps the installation within the spirit of that listing. A random door does not.
One more caution: the "36" in the model name is nominal. Aftermarket listings for this family quote an opening around 36 inches wide and roughly 22 inches tall, but as-installed openings vary with refractory panels, hearth height, and how the surround was finished. Never order a door off the model number alone — measure your actual opening.
Our Approach: Doors Built to the 1/8-Inch
ExceptionalFire builds replacement doors for discontinued prefab fireplaces as a specialty, and the Temco TLC36 family is squarely in our wheelhouse. Here's the path:
- Identify it in 15 seconds. Snap a photo of your fireplace and upload it to our AI Fireplace Expert. It matches the face, louver pattern, and frame style against our model library and tells you what you're looking at — even when the rating plate is gone.
- Price it instantly. Open the configurator on our prefab fireplace door collection, enter your measurements, pick frame finish, glass, and handle style, and see your price on the spot. No "request a quote" black hole.
- We build it to your numbers. Each door is fabricated to the dimensions you provide, to the 1/8-inch, with tempered safety glass and an inside-fit frame designed for zero-clearance fireboxes. It arrives ready to install with basic hand tools — screwdriver and drill, no welding, no masonry work.
How to Measure Your TLC36
You need three numbers: opening width (measure at top, middle, and bottom — use the smallest), opening height (left, center, right — again the smallest), and the depth of any obstruction just inside the opening. Take the measurements with the screen pulled aside and note anything unusual, like a raised refractory floor panel. Our step-by-step measuring guide walks through each measurement with photos, and if two of your numbers disagree, send us both — we'd rather see the raw data than a rounded guess.
What NOT to Do with a TLC36 Door
| Don't | Why |
|---|---|
| Burn with tempered-glass doors fully closed | Standard prefab doors use tempered glass, which is not rated for direct sustained flame heat. Burn with the doors fully open; close them only as the fire dies down or when the fireplace is cold, to stop draft loss up the flue. |
| Install an overlap-fit masonry door | It has nothing solid to anchor to on a prefab face and can block the louvers that cool the unit. |
| Block or cover the louvers/vents | They circulate room air around the firebox. Covering them can overheat the fireplace and the framing around it. |
| Order from the model number without measuring | Actual openings vary between installations of the same model. |
| Drill into the firebox liner or refractory panels | Doors mount to the front frame flange only. Penetrating the firebox compromises the unit. |
Frequently Asked Questions
What size fireplace doors fit a Temco TLC36-3?
The TLC36 family takes an inside-fit prefab door sized to your measured opening — nominally a 36-inch-wide firebox, but every installation should be measured before ordering. We build each door to your exact numbers rather than forcing a stock size.
Are original Temco TLC36 replacement doors still available?
No. Temco ceased production decades ago and OEM door kits are discontinued. Remaining "Temco-style" stock doors come in one fixed size; a custom-built door is the reliable route, especially if your opening is out of square.
Can I close the glass doors while the fire is burning?
Not with standard tempered glass on a prefab fireplace. Keep the doors open during the burn and close them once the fire is out to cut heated-air loss up the chimney — that's where doors earn their keep.
Will a door for a TLC36-2 fit a TLC36-3I?
The -2, -3, -2I, and -3I revisions share the same front frame design, so a properly measured door for one will generally suit the others. Measure your unit either way — it's the measurement, not the suffix, that guarantees fit.
