It measures 6 inches inner diameter, 8 inches outer diameter, and 18 inches in length. This pipe is part of the Selkirk Chimney System, commonly known as SCS, which is engineered to vent appliances burning wood, Number 2 fuel oil, natural gas, and LP gas. HVAC technicians and heating contractors rely on this type of chimney pipe for reliable, code-compliant venting in both new construction and retrofit installations. The stainless steel construction resists corrosion from flue gases and condensation, making it a durable choice for long-term residential heating applications. This pipe section is specifically designed for gravity-fed, natural draft venting systems. It is intended for non-positive internal pressure applications only, which means it works with appliances that maintain neutral or negative draft at the appliance outlet. This includes power burner appliances such as oil furnaces, as long as they operate within those draft conditions. The system is also well-suited for modern high-efficiency airtight wood stoves, which require carefully managed venting to perform safely and efficiently. Proper chimney pipe sizing and material selection are critical for preventing creosote buildup, backdrafting, and carbon monoxide hazards. Using a manufacturer-matched system like the Selkirk SCS ensures that all components fit together correctly and meet relevant safety standards. This 18-inch section provides a solid building block for assembling a complete vertical or offset chimney run in a residential setting. Heating professionals use sections like this one to achieve the required total flue height and proper clearances from combustible materials.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eStainless steel construction provides long-lasting corrosion resistance against flue gases and moisture\u003c\/li\u003e\n\u003cli\u003eCompatible with wood, Number 2 fuel oil, natural gas, and LP gas burning appliances\u003c\/li\u003e\n\u003cli\u003eDesigned for gravity natural draft venting with non-positive internal pressure systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Selkirk 206018u is a stainless steel chimney pipe section sized at 6 inches ID by 8 inches OD and 18 inches long, designed for natural draft residential venting of wood, oil, and gas appliances.
