This brush meets the specifications for use with any outdoor boilers with tubes that measure 1.75" in diameter. This includes models GX15 and GX30.
There are multiple methods available to clean the GX Furnace, particularly the tubes located at the back. This brush serves as one option for cleaning the vertical tubes. It's important to note that you can also utilize this brush for cleaning the horizontal tubes; however, thorough cleaning may require the use of the nylon rod and head attachment. For effective cleaning of the horizontal tubes, we recommend using the nylon rod and head. Here's the link to that product.
