Heatilator Icon 100 Fireplace Doors — Custom Doors for the 50" Icon

Fireplace Doors for the Heatilator Icon 100

The Icon 100 is the flagship of Heatilator's wood-burning Icon series — a 50-inch firebox with a front opening of 50 inches wide by 33 inches tall per Heatilator's own architect guide. That is over 1,600 square inches of opening, a scale most door makers simply don't stock for. Off-the-shelf prefab doors cluster around 36 and 42 inches; a 50-inch opening puts you in made-to-order territory almost by definition. Which is fine, because made-to-order is the right way to buy a door for a fireplace this visible anyway.

Confirm the model

The Icon family runs Icon 60 (36"), Icon 80 (42"), and Icon 100 (50"). The rating plate inside the firebox reads I100. If the plate is buried behind a finished surround — common on statement installations like this — a straight-on photo through our AI Fireplace Expert confirms the model and the fit style without disturbing anything.

Why a 50-inch opening changes the conversation

  • Stock doors thin out above 42 inches. The aftermarket is built around the common builder sizes. At 50 x 33, "just buy a door" becomes "have a door built" — the question is only who builds it and to what numbers.
  • Span matters. A five-foot frame carrying glass needs proper structure. Doors engineered to the measured opening carry their weight without racking or sagging over years of heat cycles.
  • The fireplace is the room. At this scale the door's frame lines, finish, and glass define the wall. A made-to-order door lets you decide those details instead of inheriting them.
  • Prefab rules still apply. The Icon 100 is a zero-clearance appliance: inside-fit mounting, no firebox modification, no blocked air passages. Big does not mean masonry.

Measuring your Icon 100

Heatilator's 50 x 33 specification is the design intent; your installed opening is the reality. Measure the width at the top, middle, and bottom, and the height at the left, center, and right — the steps are in our measuring guide — and use the smallest numbers. On an opening this wide, even a small variance across the span matters, which is exactly why we build to your figures and back them with the Perfect Fit Guarantee.

Frequently asked questions

What size doors fit the Heatilator Icon 100? The published fireplace opening is 50" wide by 33" tall. Doors for it are built to the measured opening rather than pulled from a shelf.

Can I use two smaller stock doors side by side? No — paired stock doors leave seams, gaps, and unsupported spans. One frame, built to the full opening, is the correct construction.

Can I burn wood with the doors closed? Only with glass rated for it. Standard tempered glass stays open during a fire. If you want the doors shut while the fire burns, talk to us about ceramic glass before you configure.

Where is the model number? On the metal rating plate inside the firebox — side wall or behind the lower grille. A photo to the AI Fireplace Expert works when the plate doesn't.
