Schaefer Brush 36406 Round Chimney Brush 6 Inch

Product Description

The SCHAEFER BRUSH 36406 is a round chimney brush designed for cleaning flue liners, chimney tiles, and vent passages in residential and light commercial heating systems. The brush body is constructed from tempered steel wire bristles, which provide durable scrubbing action against creosote, soot, and debris. It measures 6 inches in diameter and connects to standard flexible or rigid chimney rod systems via a 1/4 inch NPSM male threaded fitting. The 36406 weighs 1.7 pounds, making it manageable for single-person chimney sweeping operations. Certified chimney sweeps and HVAC service technicians are the primary installers of this tool.

This brush is suited for use on round flue liners in masonry chimneys and prefabricated metal flue systems. A 6-inch diameter brush is a common fit for flue tiles and factory-built chimney sections found in many residential gas, oil, and wood-burning appliance installations. It is typically used as part of an annual chimney inspection and cleaning procedure to maintain proper draft and reduce fire hazard. The 1/4 inch NPSM male connection is compatible with standard chimney rod systems available through most trade suppliers.

Installation Notes

Chimney brushing is typically performed by certified chimney sweeps or HVAC service technicians following NFPA 211 guidelines. Ensure the appliance is completely cooled and the damper is closed before beginning a top-down sweep to contain debris. Connect the brush securely to compatible chimney rods before inserting into the flue, and do not force an oversized brush into a liner as this can damage tile joints. Appropriate personal protective equipment including eye protection and a dust mask is recommended during the cleaning process.
