Napoleon High Definition 81: a fire shared between two rooms

The Napoleon High Definition 81 is a see through gas fireplace for the wall between two rooms. See through means there is glass on both sides, so both rooms get the fire. The glass is about 37 inches wide and 31 inches tall. You can have hand painted logs for a wood fire look, a glass ember bed, or mineral rocks. Lights inside give the firebox a glow even when the fire is off.

Order it for natural gas or propane. Direct vent means it needs no chimney. A sealed pipe through the wall or roof carries the exhaust out and brings fresh air in. It puts out up to 60,000 BTU, shared between the two rooms. A remote control and battery backup come with it. On the page, you must pick the fire bed: logs, glass embers, or mineral rocks. Reflective back panels are also a required choice. Napoleon backs it with its President’s Limited Lifetime Warranty. Want another two room option? See the Napoleon Ascent Multi View see through gas fireplace. The Napoleon High Definition 81 ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

Which Fireplace Do I Need?

Fireplace Finder

Answer a few quick questions and we’ll show you the right kind of fireplace for your home or backyard, plus the models that fit.

Where will your fireplace go?

What kind of fire do you want outside?

How do you want it built?

Outdoor fireplaces come two ways: a finished piece you set in place, or a firebox that gets built into a wall.

How big a fireplace do you picture?

Measured by the width of the fire opening, or of the whole unit for ready-made pieces.

What kind of fire do you want?

Not sure yet? Pick “Help Me Choose” and we’ll ask two easy questions.

Do you have natural gas at home, or would you use a propane tank?

Which sounds most like you?

What type of unit do you picture?

Can a vent pipe go through an outside wall or the roof?

Gas fireplaces either vent outside (direct vent) or need no vent at all (vent-free).

What matters most to you?

How big is the space you want to heat?

Enter the square feet of the room, or of the open area the fire will warm.

FAQ

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.
