Napoleon Ascent Linear 46: a wide gas fire with topaz glass included
The Napoleon Ascent Linear 46 is a direct vent gas fireplace built into a framed wall. The glass measures about 42 inches wide by 17 inches tall. Linear means the fire forms a wide, low band of flame. It burns over a bed of crushed topaz glass, which comes with the fireplace. This gives you a glass bed instead of logs.
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 24,000 BTU, enough to warm a living room. A battery backup control system comes with it. You can add a blower to move that warmth into the room, log kits, decorative back panels, a remote control, and more on the page. Napoleon backs it with its President’s Limited Lifetime Warranty. Want a wider fire? See the Napoleon Ascent Linear 56 gas fireplace. The Napoleon Ascent Linear 46 ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

FAQ
What exactly is a direct vent fireplace like the Ascent Linear 46?
A sealed gas fireplace that vents exhaust outdoors and draws combustion air from outdoors through one concentric pipe — no chimney, no open flue, and no consumption of the air you breathe indoors.
How do I keep the Ascent Linear 46’s glass clear?
A seasonal clean with gas-fireplace glass cleaner — applied only after the unit is fully cool, per the manual — removes the light white film that develops. Skip ammonia sprays; they etch ceramic glass.
How much natural gas does the Ascent Linear 46 consume?
About 0.24 therms per hour at its 24,000 BTU maximum — roughly 35 cents hourly at typical U.S. gas prices.
What are the framing specs for the Ascent Linear 46?
Minimum framing is 47.38 in wide x 39.38 in high x 18.56 in deep; the BL46 itself measures 46.94 x 39.06 x 18.31 in around its 41.65 x 16.75 in linear flame.
Is a blower part of the Ascent Linear 46 package?
Yes — the internal blower is standard equipment, converting the linear flame’s 24,000 BTU into circulated, room-filling warmth.
Can wood ever be burned in the Ascent Linear 46?
Never — it is a dedicated gas appliance. Solid fuel of any kind is a safety hazard in a sealed gas firebox and voids Napoleon’s warranty immediately.
How is the Ascent Linear 46 warrantied?
With Napoleon’s President’s Limited Lifetime Warranty — full factory coverage that our authorized-dealer status keeps intact. Compare widths across our direct vent fireplace collection.

What Our Customers Say
D
A sauna turns your garden into a spa oasis. We debated it for a while, but after renovating our house, we pulled the trigger and bought a sauna from Norse Steam and Maya. She was always super responsive and helpful throughout the process. Don't kid yourself, getting a really nice sauna is not that easy. Sizing and heating need to be figured out, as does the building, but we have always had a helpful partner on our side. She never upsold us on anything we didn't need, and we got some nice freebies when the sauna was delivered. And now we can really enjoy every moment in our garden.
KF
I'm really happy with my sauna purchase. Maya gave above and beyond excellent customer service. She wasn't pushy and gave impressive followup after the delivery to make sure everything was just right.
DE
I enjoy my FD2 Sauna with Red Light, Infrared and radiant heat. Use it 5x a week and my post workout soreness is minimal and sleep great. Maya at Norse Steam was excellent to work with.
B
We purchased the 3-person sauna for our outdoor garden. We chose the cube sauna for the aesthetic and could not be happier.
I assembled by myself except for the 2 large panels (requires a few people). Instructions were good - took me two partial Saturdays to complete and a few hours to unpack and organize in advance of assembly. Had my elec. add a NEMA enclosure on the back for the controller and power for lights and a 2nd panel for the wireless control.
Customer service was excellent
MP
Awesome Sauna and Awesome Company and Experience purchasing it from Maya!
After much research I chose the Finnmark FD-2 and it has met and exceeded all my expectations! Easy to assemble and it functions great - just as advertised. I highly recommend it for home use!
EA
Recently purchased the Finnmark one person after much research. Extremely happy with it and the ordering process. Maya was very responsive and helpful during the process and keeping us updated while we waited for shipment. There were several places I could have ordered this, but i chose Norse Steam based on the communication and customer service which was fantastic. The shipment was also excellent. The setup was pretty seamless for two people - but the best part is the sauna experience 10/10
G
Maya is amazing - super helpful and responsive. Looked at many stores, these guys have the best prices and service. Highly recommend
GR
Norse Steam, and specifically Maya, were extremely helpful as I was making the decision for our Sauna. I was able to get all of the necessary details to make a decision as construction was happening in my backyard to make space for it.
We absolutely love the CL7G. It is extremely comfortable for 6 people (can fit more less comfortably). The Thermory Spruce and Aspen in the interior smells great. The lighting is lovely. We paired the CL7G with the Harvia Spirit 10.5kw.
RS
Had great experience shopping at Norse Steam for the new heater. They had very good deal, with rocks. Customer service was good, and responded very fast with my questions. Received the heater, and it looks good, and the quality seem to be great. Will install soon, and am very excited to start experiencing sauna the way it ment to be

Can highly recommend Norse Steam for others.
JR
Smoking Hot Tub!
I got the Norse Steam SaunaLife wood-fired hot tub, the S4N model, and its been seriously great. It heats up quicker than I expected, usually around an hour and a half, and once its hot, it stays that way for a good long while. The wood-fired system is simple to use, and honestly kind of fun.
The tub itself feels solid and well put together. The thermo-spruce exterior looks beautiful in person, and the fiberglass interior is smooth, deep, and easy to clean. Its the kind of setup that just works without a bunch of fuss, which I really appreciate.
Also, the team at Norse Steam was genuinely great to work with. Super helpful, quick to respond, and made the process really easy from start to finish. It felt like they actually cared that I was happy with it. The tub has totally become a go-to way to unwind, and I wouldnt change a thing.

Great service

The heaters robust performance and durable stainless steel construction make it ideal for larger sauna spaces, providing consistent heat and a relaxing environment. Its compatibility with advanced controls ensures a personalized sauna experience every time.
The customer service team was exceptional, prompt, knowledgeable, and helpful throughout the purchase process. They ensured smooth delivery and provided clear guidance on installation and operation. Overall, I highly recommend Harvia Club for anyone seeking premium-quality sauna equipment backed by excellent support!

Great Sauna & Purchase Experience
Great experience purchasing Finnmark FD-2 from Norse Steam. Good communication and easy to assemble. Temperature increases quickly (30 minutes or less to 140) and maintains well. So far this has been a great purchase.
M
Great sauna and great customer service
We purchased the Finnmark SD-1 sauna. Maya was extremely helpful with the purchase. We had an issue with the sauna not reaching the maximum temperature, and Maya connected us with the appropriate technician that explained how to correct the issue. The sauna now heats to the maximum temperature (170 degrees) in less than an hour, and it is a great unit. We are very happy with it, and we would definitely purchase from NorseSteam if we needed any other items.

Sauna Review
I recently purchased a sauna from Norse Steam, and I couldn't be more impressed with the entire experience. From start to finish, their customer service was exceptional, and Maya deserves special recognition for her outstanding support!
Maya was incredibly knowledgeable and patient, answering all my questions about the sauna features, installation process, and maintenance. She went above and beyond to ensure I selected the perfect model for my home. Even after the purchase, Maya followed up to make sure everything was running smoothly and that I was satisfied with my sauna.
The sauna itself is top-notch beautifully designed, durable, and easy to use. It's clear that Norse Steam takes pride in the quality of their products and their commitment to customer satisfaction.
If you're considering a sauna, I wholeheartedly recommend Norse Steam. With their excellent customer service and high-quality products, you're in great hands. Thank you, Maya, and the entire Norse Steam team for a fantastic experience!
