4-Inch Insulated Chimney Pipe - 36-Inch Length

This 4-inch insulated chimney pipe is a 36-inch fixed length designed for compatible small-diameter chimney installations. Manufactured by Selkirk as part of the Model HT / Ultra-Temp family, it provides a factory-built insulated chimney section for installations that require a listed 4-inch chimney system.

Selkirk's current Ultra-Temp literature lists its 4-inch chimney system to UL 103 Type HT in the United States. The system uses stainless steel construction with 1-inch solid-pack insulation and requires 2 inches of clearance to combustible materials when installed according to the manufacturer's instructions.

Why Use Insulated Chimney Pipe?

Insulated chimney pipe helps maintain flue-gas temperature as exhaust travels through colder areas of the installation. That can support stronger draft and more consistent chimney performance compared with using uninsulated connector pipe where insulated chimney is required.

This 36-inch section is commonly used as part of a vertical chimney run, through approved ceiling or roof transitions, or on exterior portions of a compatible installation. The exact components required depend on the appliance, structure, chimney route, and local code requirements.

36-Inch 4-Inch Chimney Pipe Features

• Inside diameter: 4 inches
• Nominal length: 36 inches
• Insulation: 1-inch solid-pack insulation
• Clearance: 2 inches to combustibles when installed per Selkirk instructions
• Listing: UL 103 Type HT for the 4-inch Ultra-Temp system in the United States
• Connection: Twist-lock style chimney connection
• Manufacturer: Selkirk

Selkirk's current 4-inch product literature lists the 36-inch fixed length as product code 204036U. Installed system length is reduced slightly at each joint because chimney sections overlap when connected, so account for joint engagement when planning the total chimney height.

Build a Complete 4-Inch Chimney System

A safe chimney installation requires more than the straight pipe sections. Depending on the route, your installation may also require supports, flashing, firestops, adapters, locking components, and a termination cap.
