Wood Stove

The Home Wizard app calculates your ideal home care program to avoid problems with your Wood Stove, but sometimes trouble can still occur. Here are answers to questions about wood stove noisy blower fan.


The blower fan under my Kozy Heat Zero clearance wood stove makes noises like grinding or squealing. I have taken it apart before and oiled it, but the sound usually comes back by the next heating season.

The blower system is made up of two Dayton fans, Model 4C549, about 4 1/2" dia.x 1 1/2 " ht., in a housing unit 15 1/2" x 3 7/8".
What can I do to service one of these properly? What can I do to keep it from recurring?
Do ashes that get sucked into the space cause problems with the fans?

If I can't fix the problem, is it possible to buy the fans or complete unit without having to go thru a dealer? Thanks


Dear Della:

For a very specific question about the problem with the fan on this particular model of zero clearance woodstove, I would suggest that you call Kozy Heat toll-free at 1-800-253-4904, or you can send them at e-mail at:

Hope this is helpful.
