Schaefer Brush 36186 Round Poly Chimney Brush 8 in

Product Description

The SCHAEFER BRUSH 36186 is an 8-inch diameter round poly chimney brush designed for cleaning flue liners and chimney passages in residential and light commercial heating systems. The flexible poly bristles conform to the interior surfaces of the flue, dislodging creosote, soot, and debris without damaging liner materials. The brush connects via a 1/4-inch NPSM male threaded fitting, which is compatible with standard chimney rod systems. Weighing 1 pound, it is easy to maneuver through vertical and offset flue runs. Chimney sweeps and HVAC technicians rely on this tool for routine flue maintenance and pre-season inspections.

This brush is suited for use in round flue liners measuring 8 inches in diameter. Typical applications include cleaning terra cotta tile liners, stainless steel liners, and cast-in-place flue systems in residential gas, oil, and wood-burning appliances. It is also appropriate for use on B-vent and Type L vent systems where the flue diameter matches the brush size. The 1/4-inch NPSM male connection threads onto most commercially available flexible and rigid chimney cleaning rods sold separately.

Installation Notes

Chimney sweeps and licensed HVAC technicians should ensure the appliance or fireplace is completely cooled and the damper is closed before beginning flue cleaning. The brush should be attached securely to compatible chimney rods before insertion into the flue. Work from top to bottom where possible to allow debris to fall into the firebox for removal. Follow NFPA 211 guidelines for chimney inspection and cleaning intervals.
