DuraVent DuraChimney II 16 inch Kit Builder: choose a whole chimney on one page
The DuraVent DuraChimney II 16 inch Kit Builder is a page for choosing a complete 16 inch fireplace chimney. Build it here without visiting separate parts pages. There is no base price, just the parts you choose. DuraChimney II is DuraVent’s air cooled chimney, a double wall pipe in 8 to 16 inch sizes for fireplaces that burn wood, oil, coal, or gas. This is the largest size. It must match your fireplace’s flue collar, the opening where the chimney connects. The fireplace maker must approve DuraChimney II.
Choose at least one pipe section, 12, 18, 36, or 48 inches long, and the quantity of each. Optional fixed 15 or 30 degree elbows are sold individually. Two make a sideways shift, but no pipe can run horizontally. Add supports, shields, flashing, and a cap as needed. The chimney normally sits inside a chase, a framed box with 2 inches of air space around the pipe. Flashing covers the chase top while leaving ventilation gaps. Need pipe separately? See the DuraVent DuraChimney II 8 to 16 inch Chimney Pipe. The DuraVent DuraChimney II 16 inch Kit Builder ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

Planning Your Installation:
The following recommendations are a general guideline to assist in the layout and selection of the chimney components needed for your installation. Always follow Duravent Installation instructions enclosed with the cap or support box before installing your chimney system. Installation instructions can be viewed online at www. duravent.com, under catalogs and instructions.
- Measure the diameter of the fireplace flue outlet. An improperly sized chimney results in poor draft and excessive creosote formation.
- Select the chimney with the same size diameter as the fireplace flue outlet. Refer to the chimney sizing chart in the back of this catalog for masonry fireplaces.
- Install the chimney in an enclosed chase.
- If possible, avoid offsets. A straight vertical installation is more efficient and less likely to develop creosote. If an offset is required to avoid rafters or other obstructions, measure the horizontal distance required and the vertical height available. Both 15° and 30° elbows are available. Elbows greater than 30° are not allowed in the United States. Two offset (four elbows) in a single installation is permitted. Refer to the offset chart in the back section of this catalog. At least one Elbow Strap is required. Elbow Straps ensure adequate support.
- Determine the minimum chimney height above the roof line. Building codes require a minimum of 3′ above the roof penetration and at least 2′ higher than any portion of a building within 10′. See figure 1. The termination cap is installed above that point.
- Chase Top Flashing is available. A pitched roof flashing can be locally made, if required. A storm collar is required for all installations using a flashing.
- Determine the total length of chimney required for the installation. To calculate the installed per length of 10″-16″ DuraChimney II pipe, subtract 1″ per joint. Minimum recommended chimney height, at sea level of straight vertical chimney, is 10′ to 15′ above the fireplace outlet. Higher elevations, or the use of elbows, will require approximately 30% to 60% more height to provide for an adequate draft.
- For a UL approved shroud, see the DuraChimney II Shrouds Installation Instructions (L181). View online at www.duravent. com, under catalogs and instructions.
- Be fire safe. Maintain at least 2″ clearance to combustibles. Follow local building codes and have your chimney inspected by a certified professional.

FAQ
How does the 16-inch DuraChimney II Customize your Kit page work?
The listing has no base price; you choose the parts and the selector totals them. The 16-inch Length of Chimney Pipe row is required (12, 18, 36 or 48 inch sections, any quantity), the Elbow row adds 15 or 30 degree offsets, and the Build Your Chimney Kit row holds the anchor plates, firestop spacer, shields, chase top flashing and collar, storm collar, cap, Bishop copper adapter and snow splitter.
What kind of fireplace uses a 16-inch DuraChimney II?
The largest wood, oil, coal or gas fireplaces with a 16-inch flue collar whose manual names DuraChimney II as an approved chimney. It is the biggest DuraChimney II diameter, a unitized double-wall air-cooled system listed to UL 103 and ULC S604 and rated for continuous 1000 F flue gas, with a 430 stainless inner and galvanized outer wall.
How is a tall 16-inch chimney supported?
Use a Wall Strap every 8 feet, a Supplementary Support once the total height passes 50 feet (each support carries 25 feet of chimney) and a Stabilizer clamped to the pipe to keep it centered in the chase. The Anchor Plate carries the base, and the Elbow Strap supports any offset. Sections twist-lock together, so screws are not normally required.
How much pipe should I order?
Measure from the anchor plate to the top, subtract 1 inch per joint, and keep to DuraVent’s minimum of 10 to 15 feet of chimney above the fireplace outlet, adding 30 to 60 percent at altitude or with elbows. The cap must end at least 3 feet above the roof penetration and 2 feet higher than any part of the building within 10 feet.
Can I use a chimney-top damper or a copper pot on this size?
Both are on the page: the Anchor Plate with Damper, which DuraVent says to use only where the fireplace manufacturer permits, and the European Copper Bishop Adapter for a decorative copper pot termination (the King adapter is not offered in 16 inch). The copper-pot instructions are linked in the Instructions tab. Smaller collars are covered in the DuraChimney II category.
What clearance and firestopping apply?
Keep 2 inches of air space to combustibles and run the chimney in an enclosed chase. Fit a Firestop Spacer at every floor and ceiling, an Attic Insulation Shield through an attic, a Roof Radiation Shield where the chimney exits the chase, and the Chase Top Flashing with a 1/2-inch air gap, then the Storm Collar and Chimney Cap. Follow local codes and have the installation inspected.

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

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.

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!
