Napoleon Altitude X 36 Direct Vent Gas Fireplace

FAQ

Does the Napoleon Altitude X 36 need a chimney?

No. It vents horizontally through a wall or vertically through the roof with sealed direct vent pipe, so it can go into virtually any room — no existing chimney, flue, or hearth required.

How much heat does the Altitude X 36 put out?

Up to 36,500 BTU, delivered through an extra-tall 35.25 x 33.13 in glass viewing area. Its LHAD heat-management system lets an installer redirect some of that heat, protecting the wall above for artwork or a television.

What does it cost to run the Altitude X 36 per hour?

Expect roughly 0.36 therms of natural gas per hour at full output — about 50–60 cents per hour at typical U.S. gas prices, dropping as you lower the flame.

How do you clean the glass on the Altitude X 36?

Once or twice a season, let the unit cool fully, remove the glass front per the manual, and clean the inside surface with a gas-fireplace glass cleaner — never household ammonia cleaners, which can etch the coated glass.

What framing does the Altitude X 36 need?

Minimum framing is 35.75 in wide x 43.63 in high x 19 in deep; the fireplace measures 35.25 x 42.44 x 18.75 in. Its shallow 19 in depth keeps the chase footprint small for a fireplace with this much glass.

What warranty comes with the Altitude X 36?

Napoleon backs it with the President’s Limited Lifetime Warranty, included in full when you buy from us as an authorized dealer. Compare similar models in our direct vent fireplace range.

Can the Altitude X 36 heat a whole house?

It is designed as a zone heater rather than a whole-house furnace. Its 36,500 BTU output can carry the main living area — often letting you lower the central thermostat — but bedrooms behind closed doors will still rely on your primary heating system.
