This is a kit that pro fab made to fix the problem of smoke drifting back to the blower and causing it to fail.
Since I put this bolt on kit on the back of my aspen 175 I have not had as many problems with my blower
but there is now a huge build up of wet thick creosote in the blower chamber and this has rusted out the metal sides.
I have since taken the kit off as to stop any further damage. I would buy a central the next time around. The
customer service at pro fab never truly fixes anything. This would be similar to the emypre pro 400

Fan failures are rare but the problem is the trapped gasses condesning in the air box

Sounds like yours was an older design

As many probs as central has with gassers there is far better options out there

maineowb, do you remove the blower and clean the airbox regularly or only when there is a problem? Is it worthwhile to do this? I bet if we pool our knowledge and keep an open mind we can get the stove on the right track.

slim, his design I believe is different than the others we have seen

this kit was years ago when they put a flapper inside originally

I have now used this boiler for 6 years and as a plumber I am also the one who installed it. I have worked on most parts of this boiler.
I have gone through three fans and then was told about the flapper kit. I have used that only one year and have had that thick buildup
several of times. During the first five years I would check the blower box and it was almost always clean and dry. The kit helps the fan situation
but has made the blower box wet with creosote that has rusted the box all around. I will have to take off the outer jacket and cut the box off and re weld
all the metal i can reach. I hope to get another year or two out of this boiler. I have been talking to pro fab for several years about all these things but
we have never come up with an answer. My front door has also rusted out. every year i fill it with concrete and weld what i can just to get by without buying a new door for
a few hundred bucks.

Thanks for all info.

my blower died after 2.5 years.

How about some pictures guys and perhaps we can help solve the problem, many of these companies are not into the in field fixes that work and only build to pass EPA, lets try to fix the issue and not destroy the company or the industry! What do you say?
