4-Inch HT Chimney Pipe Adapter

The 4-inch HT pipe adapter connects compatible 4-inch connector stovepipe to Selkirk's 4-inch insulated chimney system. It is the transition piece used where the interior connector pipe changes over to the factory-built insulated chimney system required for the rest of the chimney run.

Selkirk identifies the 4-inch chimney adapter as product HT4PA in its current Ultra-Temp literature. The adapter is designed specifically for connection to connector pipe and the 4-inch Model HT / Ultra-Temp chimney system.

What Does the 4-Inch Pipe Adapter Do?

Single-wall connector pipe and insulated chimney pipe serve different purposes and should not simply be joined together without the correct transition component. This adapter provides the proper connection point between the two sections of the venting system.

On the chimney side, the adapter connects into the compatible Selkirk 4-inch insulated chimney system. On the connector-pipe side, it provides the transition to the 4-inch stovepipe used between the appliance and the chimney system when that configuration is permitted.

4-Inch HT Pipe Adapter Features

• Diameter: 4 inches
• Manufacturer: Selkirk
• Selkirk product number: HT4PA
• Purpose: Connects compatible connector pipe to 4-inch insulated chimney
• System: Selkirk Model HT / Ultra-Temp 4-inch chimney

Use the Correct Pipe on Each Side of the Adapter

Connector stovepipe is generally used between the appliance and the point where the listed chimney system begins. Insulated chimney pipe is used through approved ceiling, roof, wall, attic, and exterior portions of an installation when required by the system design and manufacturer instructions.

Read our 4-Inch Stove Pipe Guide for a clearer explanation of the difference between connector pipe and insulated chimney pipe.

For straight connector-pipe runs, see our 1-foot single-wall pipe, 2-foot single-wall pipe, and 3-foot single-wall pipe.

Complete the Insulated Chimney Side

After the transition, build the compatible insulated chimney run with the length and support components required for your installation. Popular related parts include:

Installation and Clearance Requirements

Do not rely on a universal clearance number for every installation. Required clearances can differ between the connector pipe, insulated chimney, appliance, support components, and the structure itself. Follow the appliance manual, the Selkirk installation instructions, the connector-pipe manufacturer's requirements, and all applicable building and fire codes.

Do not modify or improvise a chimney transition in place of the listed adapter. If your installation passes through a ceiling, wall, roof, attic, or other combustible construction, use the support, shielding, flashing, and firestop components required by the chimney system instructions.

For current manufacturer specifications and installation documents, see the Selkirk Ultra-Temp chimney information.
