Description
The IMPERIAL MFG GROUP USA INC BM0013 is a 5-inch, 24-gauge black adjustable elbow designed for single-wall stovepipe systems. This fitting allows for directional changes in venting runs, connecting sections of black stovepipe at variable angles to route exhaust from wood stoves, pellet stoves, or solid-fuel heating appliances. The 24-gauge steel construction provides adequate rigidity for interior venting applications. Installers receive four elbows per package. HVAC technicians and hearth installers use this fitting to complete vent runs where straight pipe cannot be used due to structural obstructions or required offsets.
This elbow is intended for single-wall black stovepipe applications in residential and light commercial settings. It is commonly installed in the connector pipe section between a solid-fuel appliance and the chimney thimble or flue entry point. The adjustable design allows the installer to dial in the correct angle without stocking multiple fixed-angle fittings. It is not rated for use as a chimney liner or in Class A all-fuel chimney applications.

- 24-gauge steel construction provides solid, stable connections in interior venting runs

Compatibility
Designed as an OEM-style replacement or new-installation fitting for 5-inch single-wall black stovepipe systems used with solid-fuel appliances such as wood and pellet stoves.
Installation Notes
This fitting is installed by qualified hearth technicians or HVAC professionals in accordance with NFPA 211 and local building codes governing solid-fuel appliance venting. Confirm the appliance manufacturer’s minimum clearance-to-combustibles requirements before routing the elbow. Single-wall stovepipe must not pass through walls, ceilings, or floors without the appropriate thimble or transition to a listed chimney system. Allow the appliance to cool completely before servicing or repositioning any venting components.
