Napoleon Ascent 36 Direct Vent Gas Fireplace

FAQ

Can you burn wood in the Napoleon Ascent 36?

No. The Ascent 36 (B36) is a sealed gas-only appliance — burning wood or anything else in it is unsafe and will void the warranty. If you want real logs, look at a dedicated wood-burning fireplace instead.

Does the Ascent 36 need a chimney?

No chimney needed. It is a direct vent fireplace that vents through an outside wall or the roof, drawing all combustion air from outdoors, which is why it can be added to homes that never had a fireplace.

How much gas does the Ascent 36 use per hour?

With an 18,000 BTU maximum input, it burns about 0.18 therms per hour — typically 25–30 cents per hour of natural gas at average U.S. rates, making it one of the most economical fireplaces we carry.

Is a blower included with the Ascent 36?

Yes, the Ascent 36 includes an internal blower to circulate warmth into the room, so its 18,000 BTU goes further as steady, comfortable zone heat for bedrooms, dens, and mid-size living rooms.

What are the Ascent 36’s dimensions?

The unit is 35 in wide x 34.63 in high x 15.75 in deep with a 30.69 x 23.69 in viewing area; minimum framing is 35.50 x 35 x 16 in. Its slim depth suits standard wall cavities — see all our direct vent models for deeper options.

How long is the Ascent 36 under warranty?

It carries Napoleon’s President’s Limited Lifetime Warranty — the strongest coverage tier Napoleon offers — and buying from an authorized dealer like us keeps that factory warranty fully intact.

Does the Ascent 36 have to go on an outside wall?

No. Horizontal venting through an exterior wall is the simplest install, but the Ascent 36 can also vent vertically through the roof, so an interior feature wall is possible wherever a vent run can be routed to the outdoors.
