Monessen Natural Blaze See-Through: a gas log fire you can enjoy from two rooms
The Monessen Natural Blaze See-Through is a vent free burner and log set made for a see through fireplace. See-through means it sits inside a wall between two rooms, and both rooms see the same fire. It is 27 inches wide and needs an opening at least 21 inches deep. The ceramic fiber logs reflect heat into the room and look finished from either side. The burner puts out up to 39,000 BTU. It heats up to 1,400 square feet.
Order it for natural gas or propane. Vent free means it needs no chimney or vent pipe at all, and nearly all the heat stays in the room. Check your local code first, since some areas restrict vent free heaters. The price covers the burner and the logs. On the page you pick the fuel. It is millivolt with auto spark ignition: push the button and it lights, with no electricity, so it works when the power is out. You can add a hand held on and off remote or a touchscreen remote. Need a firebox instead? See the Monessen Lo-Rider Designer firebox. The Monessen Natural Blaze See-Through ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

A real wood-burning fireplace with a flue and a damper you can open.
What matters most to you?
Vented logs look the most like a real wood fire. Vent-free logs put out the most heat.
How wide is the front opening of your fireplace?
Measure across the front of the opening, from side to side. Logs sit a few inches narrower than the opening.

FAQ
What does the two-sided design of the Natural Blaze See-Through mean?
Most log sets are sculpted to face one direction. This one carries a unique design on both sides, so whichever room you view it from you see a finished, authentic stack rather than the back of the mold. Monessen builds it specifically for see-through fireplaces, where the fire shows from both faces of the firebox and needs to look right from each.
What accent materials are included with the set?
More than logs. The package includes the Natural Blaze burner as standard, plus volcanic rock, rock wool embers, and an ember bed log switch to dress the base of the fire. The glowing floor of the firebox is therefore provided out of the box rather than left as an accessory purchase, with millivolt control and auto-spark ignition handling day-to-day operation.
Do the logs themselves contribute to heat output?
They do. The pieces here are ceramic fiber, a material Monessen uses because it reflects more heat back into the room instead of absorbing it. Combined with vent-free operation and the 39,000 BTU burner rating, that material choice is part of how this set turns its numbers into warmth you can actually feel in both connected spaces.
Why is the minimum depth 21 inches when single-sided sets need 13?
This set is made for see-through fireboxes, which are simply deeper chambers. The spec calls for an opening at least 32 inches wide, 21-1/2 inches tall, and a full 21 inches front to back, versus the 13-inch depth Monessen’s single-sided sets require. Within that deeper opening the 27-inch stack sits with a finished face presented toward each room.
Where does this set rank for output among Monessen vent-free logs?
At the top of its burner family. The 27-inch see-through runs 39,000 BTU, above the 37,000 ceiling of the single-sided sets built on the same burner technology, and it is rated to warm up to 1,400 square feet. Natural gas and propane versions are both offered. Browse the rest of our ventless gas logs for the single-sided options.
Why do gas logs often look unfinished from the back?
Because most sets are sculpted and detailed only on the side that faces the room; nobody expects the rear to show. In a see-through fireplace both sides are on display, which is exactly the problem this set was designed to solve: its stack is finished on each face, so there is no bad seat in either room.
Does the fire still look right from a sharp viewing angle?
That is one of its design goals. Monessen states the included burner produces realistic flame viewing from a wide range of angles, not just head-on, and the double-faced stack backs that up with authentic detail wherever your seat happens to be. For a firebox open to two spaces at once, off-axis viewing is the normal case rather than the exception.

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

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

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.

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

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 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.

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!
