Use Only as Connector Stovepipe

This elbow is part of the single-wall connector section between the appliance and the listed insulated chimney system. It is not a substitute for insulated Class A chimney where the venting system passes through walls, ceilings, roofs, attics, or other combustible construction.

At the required transition point, use the 4-Inch HT Pipe Adapter and compatible insulated chimney components.

Build the Connector Run

Pair this elbow with the straight connector lengths needed for your layout:

• 4-Inch Single-Wall Stove Pipe - 1-Foot Length
• 4-Inch Single-Wall Stove Pipe - 2-Foot Length
• 4-Inch Single-Wall Stove Pipe - 3-Foot Length
• 4-Inch Slip Joint Connector

Plan the Whole 4-Inch Venting System

Installation and Safety

Every change in direction affects the venting layout, so use elbows only where needed and follow the appliance manual for permitted connector configuration, rise, clearances, fastening, and chimney requirements. Do not rely on a universal clearance number for every appliance or connector-pipe system.

For general heating and chimney safety information, see the U.S. Fire Administration heating fire-safety guidance.
