DuraVent DuraChimney II 8 inch 15 Degree Elbow Kit: a small sideways step around a rafter or joist
The DuraVent DuraChimney II 8 inch 15 Degree Elbow Kit is a pair of angled chimney fittings with a support strap. The two elbows move the chimney sideways around a rafter or joist, then point it straight up again. This sideways section is called an offset. Both elbows have a fixed 15 degree bend, so you cannot adjust their angle. Each pipe length in the offset needs a strap of its own. The kit includes one strap, so a longer offset with more pipe sections needs extra straps. A chimney can have no more than two offsets.
This kit fits only the 8 inch DuraChimney II family, which uses twist lock joints. 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. Its parts cannot be modified or combined with DuraTech, DuraPlus, or another brand’s chimney. Need a bigger sideways step? See the DuraVent DuraChimney II 8 inch 30 Degree Elbow Kit. The DuraVent DuraChimney II 8 inch 15 Degree Elbow Kit 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
What is in the 15-degree Elbow Kit for 8-inch DuraChimney II?
Two 15-degree elbows and one elbow strap, sized for 8-inch DuraChimney II only. The pair lets the chimney step sideways around a rafter, ridgepole or joist and then return to vertical; the strap carries the weight of the pipe above the offset so the elbows are not loaded. The elbows are fixed at 15 degrees and are not adjustable.
When should I choose the 15-degree kit instead of the 30-degree one?
Use 15 degrees when the obstruction only needs a small sideways step; it keeps the flue closer to vertical, which drafts better and collects less creosote. The 30-degree kit reaches further per foot of rise. The DuraChimney II offset chart in the catalog shows how much horizontal reach each angle gives for a given length of pipe between the elbows.
How many offsets can an 8-inch DuraChimney II have?
A maximum of two offsets, four elbows in total, and nothing steeper than 30 degrees; that is a UL 103 limit in the United States. Each offset needs at least one elbow strap, so buy a second kit or a strap for a second offset. DuraVent advises a straight vertical run wherever possible and roughly 30 to 60 percent more chimney height when elbows are used.
Are these elbows compatible with DuraTech or DuraPlus?
No. They fit the 8-inch DuraChimney II air-cooled system only, and DuraVent does not allow its chimney lines to be mixed. The elbows twist-lock onto the chimney sections like the straight pipe, so screws are not normally required, and the 2-inch clearance to combustibles applies through the offset.
Do I still need a firestop at an offset in a ceiling?
Yes. Building code and DuraVent’s instructions require a firestop at every floor or ceiling the chimney passes, offset or not, and an attic insulation shield where it crosses an attic. Plan the offset so the elbows sit clear of the framing and the straight sections pass through the firestop opening with 2 inches of air space all round.

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

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.

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!
