Imperial Mfg Group Usa Inc BM0026 Adjustable Flue Stop

Product Description

The IMPERIAL MFG GROUP USA INC BM0026 is a black adjustable flue stop designed to seal the space around a flue pipe where it passes through a ceiling or floor. Constructed from 24-gauge steel and finished in black, this flue stop adjusts to fit round flue pipe diameters from 6 inches up to 9.5 inches. It provides a clean, finished appearance at the penetration point while helping to limit air movement between floors. Licensed HVAC technicians and heating contractors install this component during new installations and service calls on vented heating appliances.

This adjustable flue stop is suited for residential and light commercial applications where B-vent, single-wall, or other round flue pipe passes through a ceiling or floor assembly. The adjustable design accommodates a range of pipe sizes without requiring separate SKUs for each diameter, making it a practical stocking item for service vans and supply houses. It is typically installed on gas furnaces, boilers, water heaters, and other atmospherically vented heating equipment.

Installation Notes

Installation is performed by a licensed HVAC technician or heating contractor. Shut down and allow the heating appliance and flue pipe to cool completely before handling components at the penetration point. Verify local building codes and the International Fuel Gas Code (IFGC) for required clearances between single-wall flue pipe and combustible materials. Do not use this flue stop as a firestop or draft-stopping device unless the product is specifically listed and labeled for that purpose.
