The Napoleon High Definition gas fireplace is the first See Through fireplace in the industry to offer so many dynamic design choices for firebox design.
The clean-faced surround design is understated ensuring that it’s all about the fire.
Stick to a rustic and traditional feel with beautifully hand-painted PHAZER® Logs and the split burner system produces beautiful YELLOW DANCING FLAMES® or give the look a modern twist with the Topaz CRYSTALINE™ Ember Bed and burner or the natural-looking Mineral Rock Media Burner.
Besides supplying two rooms with exceptional focal points, the High Definition also features a dual NIGHT LIGHT® which illuminates the ember bed and firebox while gently adding a glow to the room, even when the fire is off.
One fireplace, two rooms, exceptional views, the High Definition is a gorgeously refined fireplace.

Why is the High Definition 81 special in Napoleon’s lineup?
Raw output and picture: 60,000 BTU — the strongest indoor unit we carry from Napoleon — behind a 36.75 x 30.75 in two-sided-view firebox with a deep, traditional flame presentation (HD81NT-1).
Can the High Definition 81 heat a large open area?
Yes — 60,000 BTU with the included internal blower is genuine whole-zone heating for big great rooms; many owners treat it as their primary evening heat source.
What framing does the High Definition 81 need?
A substantial minimum opening of 54.50 in wide x 49.50 in high x 27.75 in deep — its 28.75 in deep firebox is the largest of our Napoleon indoor units. Build strictly to the installation manual.
Does the High Definition 81 need a chimney?
No — even at 60,000 BTU it is direct vent: one sealed pipe through the roof or wall covers exhaust and combustion air, with no masonry chimney required.
What does the High Definition 81 cost to run?
About 0.60 therms of natural gas per hour at maximum — roughly 90 cents hourly at average U.S. rates — with the flame-height control trimming that substantially in normal use.
Is the High Definition 81 outage-capable?
Yes — battery backup on the ignition lights it without power, which matters most on a unit strong enough to carry a whole zone in a storm; the blower resumes with electricity.
What is the warranty on the High Definition 81?
Napoleon’s President’s Limited Lifetime Warranty — full factory coverage, preserved through our authorized Napoleon dealer status.
