Shop by Brand - Marco - Builder's 41" B41 Series

Builder's 41" B41 series fireplaces.  The newer revision B41 circulating models allowed for either the FBK-100 or FBK-200 blower kit, while the older revision models used the #793623 and 793630 axial fan kits.  The FBK-100 and FBK-200 blower kits are still available.  You can determine if your fireplace uses either of these kits by removing your lower access panel and looking for two flush mounted tabs on the floor of the insert.  These tabs secure the blower's bracket assembly to the floor and indicate acceptable fitment of the FBK-100 or FBK-200 blower.  


Other models may not be listed, so be sure to consult with your owner's manual before purchasing.

Need help finding the correct blower or fan kit for your fireplace? Let our experts help you track down the correct replacement blower, fan kit or part for your application. We typically only need the fireplace or stove's make and model to determine exactly what you need. This information can usually be found on gas fireplaces by removing the lower access panel and finding your fireplace's name tag or identificaton card. Wood inserts will often times have the same identificaton card, while freestanding stoves and others might have this information printed on a rear panel or door.

Once you've located your fireplace's brand and model information, simply use the Find Your Blower tool above, or the Help Find My Blower at the top of the page.
