Understanding 18 inch Selkirk Ultra-Temp / Galva-Temp

For 18 inch listed factory-built chimney pipe in the Selkirk Ultra-Temp / Galva-Temp product line, correct selection begins with the job the product needs to perform. Ultra-Temp and related Selkirk pipe systems use their own joint and accessory specifications for approved chimney applications.

Appliance and vent system

Stove connector, factory-built chimney sections, and liners used in an existing chimney are not substitutes for one another. This group is organized around 18 inch. Check whether the number refers to a single nominal vent diameter or, in concentric designs, a pair of passages; actual dimensions can vary by series. The Selkirk Ultra-Temp / Galva-Temp family is a useful way to narrow the search, but its joint style and approved accessories still need to match.

Selection details that matter

  • Confirm the appliance manufacturer, model, fuel, and approved vent category or vent family.
  • Match 18 inch nominal dimensions, wall construction, joint design, and all required adaptors.
  • Review elbows, tees, supports, wall or roof penetrations, clearances, and termination instructions.
  • Check whether any transition or substitute component is explicitly authorized by the manufacturer.

Venting layout and safety checks

A complete system may need more than a straight pipe section. Depending on the approved installation, review support hardware, turns, flashing, firestops, adaptors, cleaning access, and the appropriate termination. The permitted route and clearance to combustibles come from the appliance and vent manufacturer, not the category label. Confirm the exact Ultra-Temp/Galva-Temp series and matching supports, flashing, and caps. Determine where the system transitions from connector or liner to its listed chimney/termination arrangement, and account for structural support.

Does Selkirk Ultra-Temp / Galva-Temp 18 inch work with any existing chimney?

Not necessarily. A factory-built chimney is a listed system whose joints, supports, and penetration accessories need to match the model family. Compare the approval and installation manual for the exact appliance.
