The IMPERIAL MFG GROUP USA INC BM0346 is a 4-inch, 28-gauge single-wall black adjustable elbow designed for use in stove pipe venting systems. It connects sections of venting pipe and allows angular adjustment to route exhaust from wood stoves, pellet stoves, or similar solid-fuel appliances through walls or around obstructions. The 28-gauge steel construction provides durability in typical residential venting applications. This elbow is sold in a package of 4 units. Installation is performed by HVAC technicians or qualified stove installation professionals.
This adjustable elbow is suited for residential solid-fuel appliance installations where flexible routing of single-wall stove pipe is required. It is commonly used in new installations and retrofit projects where the venting path requires a direction change. The adjustable design accommodates a range of angles, reducing the need for multiple fixed-angle fittings on a job site.
Designed as an OEM-style replacement and standard fitting for 4-inch single-wall black stove pipe venting systems used with solid-fuel appliances.
Installation should be performed by a qualified technician in accordance with local building codes and appliance manufacturer guidelines. Shut down and allow the appliance and existing venting to cool completely before servicing or replacing any pipe sections. Single-wall stove pipe must maintain required clearances to combustibles as specified by the appliance manufacturer and applicable codes. Do not use single-wall pipe for through-wall or through-ceiling penetrations where listed double-wall or insulated connector is required.
