The Selkirk 210036u is a UT Series Ultra-Temp insulated chimney pipe designed for reliable venting in both residential and commercial heating applications. This section measures 10 inches inner diameter by 12 inches outer diameter and 36 inches in length, providing a consistent and secure flue pathway for wood-burning stoves, fireplaces, boilers, and other solid-fuel appliances. The pipe is constructed from 430 stainless steel, a grade well known for its heat resistance, corrosion resistance, and long service life in high-temperature venting environments. Insulated chimney pipe is critical for maintaining proper draft, reducing creosote buildup, and keeping flue gases at the temperatures needed for safe and efficient exhaust. The air space or insulation layer between the inner liner and the outer wall helps the flue reach operating temperature quickly and stay there, which reduces condensation and the harmful deposits that come with it. HVAC installers and chimney professionals rely on insulated class A chimney pipe systems for applications that require the pipe to pass through or near combustible materials, including walls, ceilings, and attic spaces, where maintaining clearance-to-combustibles standards is essential. The Ultra-Temp UT Series is engineered for straightforward installation. The small-diameter coupling system uses a twist-lock mechanism so sections connect quickly without special tools. Once locked, a slim design lock band conceals and protects the seam, adding a clean finished look and extra security at every joint. This system works well for small residential builds as well as large custom chimney projects where consistent, fast assembly matters. Contractors appreciate the reliable fit and finish that reduces time on the job site. Replacement sections like the 210036u are commonly needed during chimney rebuilds, system extensions, or code-compliance upgrades. This pipe section is a direct fit within the Selkirk Ultra-Temp UT Series lineup.
The Selkirk 210036u Ultra-Temp UT Series insulated chimney pipe delivers durable, code-ready venting performance in a stainless steel design that installs quickly and fits seamlessly into both new construction and retrofit chimney systems.
