Imperial Mfg Group Usa Inc BM0080 Black Flue Reducer

Product Description

The IMPERIAL MFG GROUP USA INC BM0080 is a 24-gauge black flue reducer designed to transition between an 8-inch and 7-inch round flue section in residential and light commercial venting systems. The small end is factory-crimped for straightforward insertion into the next flue section without additional field modification. Licensed HVAC technicians and plumbers install this fitting when connecting mismatched vent pipe diameters on single-wall black stovepipe or appliance connector runs. At 13.57 pounds per carton of 12 units, each reducer is lightweight enough for single-person handling during installation.

This reducer is intended for use in single-wall black flue pipe applications, including those serving wood-burning stoves, fireplaces, and solid-fuel or gas appliances that require a standard black steel connector. It fits into venting configurations where the larger 8-inch collar must step down to a 7-inch flue pipe, accommodating common vent diameters found in residential heating installations. Sold in cases of 12, it is a practical stocking item for HVAC distributors and service contractors who handle multiple installations.

Key Features

• Steps down from 8 inches to 7 inches for standard flue diameter transitions
• 24-gauge black steel construction suitable for single-wall flue connector applications
• Factory-crimped small end simplifies insertion into downstream pipe sections
• Consistent sizing across a 12-unit case pack supports high-volume stocking

Compatibility

Designed as an OEM-style replacement fitting for single-wall black stovepipe and appliance connector systems requiring an 8-inch to 7-inch round flue reducer.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified tradesperson in accordance with the appliance manufacturer instructions and applicable local codes, including the International Fuel Gas Code where required. Ensure the connected appliance is fully shut down and the flue is cool before beginning any vent pipe work. The crimped end inserts into the receiving pipe in the direction of flue gas flow; secure all joints per local code requirements. Single-wall black flue pipe must maintain the clearances to combustibles specified by the appliance manufacturer and local jurisdiction.
