Schaefer Brush 36166 Round Poly Chimney Brush 6 in

Product Description

The SCHAEFER BRUSH 36166 is a round poly chimney brush designed for cleaning flue liners, chimney tiles, and vent passages in residential and light commercial heating systems. The 6-inch diameter head uses poly bristles, which are suitable for removing soot, debris, and light creosote deposits without scoring softer flue surfaces. The brush connects via a 1/4-inch NPSM male fitting, making it compatible with standard chimney rod extension systems. Chimney sweeps and HVAC technicians use this brush as part of routine flue maintenance and pre-season inspection work.

This brush is suited for use in round flue liners measuring 6 inches in diameter, including terra cotta tile liners and some factory-built metal flue systems. It is commonly deployed during annual chimney inspections, post-season cleanouts, and as part of compliance checks with NFPA 211 guidelines for solid-fuel heating appliances. The 1/4-inch NPSM male connection threads directly onto compatible chimney rod sets for variable-depth cleaning access.

Installation Notes

Installation and use should be performed by a qualified chimney sweep or HVAC technician familiar with flue cleaning procedures. Ensure the fireplace or heating appliance is completely cooled and the damper is secured open before inserting the brush. Work from the top down where possible, and use a drop cloth or firebox seal to contain debris at the firebox opening. Follow NFPA 211 and local jurisdiction requirements for chimney maintenance intervals and documentation.
