What the heck are they doing with an SWG power vent??

PostBy: Carbondale On: Fri Jan 10, 2014 2:37 pm

Hi guys... Happy New Year

I have an SWG 4 SS on my stoker. I want to purchase a motor and fan kit so that I have it in stock should I have a failure. Imagine that, me being proactive. I see a replacement assembly from Patriot supply PN 46234800. The information on the description says; do not use for coal and wood stoves. This was interesting since this is the unit that came with my stove from Reading. I called Field Controls and was told that they do not test them for coal and wood and if the stove manufacturer does, then that is why they shipped the unit with the stove. Sounds like finger pointing liability away. Anyway, Field Controls told me to buy the unit from the stove manufacturer. I don't want to get pruned doing this if I can get one from Patriot Supply for a better price. I called Patriot Supply and was told that the stove manufacturers are doing something to the units to prevent the buildup of fly ash on the blower fans. The guy I spoke to said that he does not know what it is and they could not find out when they asked. He said that he has had people buy the blower kit from them for a coal and wood application and they have failed in a short period of time. When this happens Field Controls does not honor the warranty because of the application. Does anyone know what the modifications are that the stove manufacturers are doing to the power vent units? If so, is it something that someone could do to the standard unit? Sorry for all the words. Thanks!

When we forked out about $20,000 for the UL testing we should be able to have at least a long term plan to make that money back. At the current rate we should see profit in about 20-25yrs. :cheers:


P.S. The secret to longevity is keeping the blower motor and fan assembly clean and remove from high humidity conditions during the summer. And using the correct SWG oil that is recommend.

Oh yea, this is a secret don't tell anyone else. Mums the word .OK :)

edited to remove comment because it was taken in the wrong manner even though smiley's were used to convey a little light hearted joking!

Wow ask a serious question and get smart ass answers. That's OK

It wasn't a question on longevity and maintenance, it was a question on whether there are modifications made to the unit to handle the fly ash.

Sorry for the bother.

Touchy today ? :) Besides my answer was very serious and was directed at your statement that the mfgs. are pruning people. I can assure you we will not get rich selling powerventers.

There's a really good group of very knowledgable folks on this forum who freely offer their help and advice. And guess what? We joke around some too. Nobody intended their response to be a smart ass answer. If you felt it was meant that way then sorry, but you are wrong. Grow some skin and maybe develop a sense of humor. If that doesn't work, I've got no advice for you.....ever.

The original question certainly was about a concern with longevity and Flyer answered it. No reason to get snippy.

I was just joking too... hahahaha

Thanks for your answers.. I take away that there are no modifications made to the unit itself, the value add was in getting UL certification for the application of the power vent on a coal and wood stove (I managed a dept that handled UL/CSA filings for 10 yrs at a major computer company). Sounds like Field Controls did not file certification for that use and therefore does not recommend that usage for liability concerns.

That said....are there release agents other that WD 40 that can be applied to the internals and provide more corrosion protection from the effects of fly ash..

I have an Alaska stove what uses a Field Controls SWGII-4 stainless steel power vent. I bought a new one from my coal dealer for $375 (complete unit) in Jan. 2004 and it lasted until Mar. 2013. I cleaned it and oiled it regularly to try and extend it's life. I was told by my dealer that they seldom last more than 5 years, so I was really happy to get 9 years out of it.

Last year, I decided that I would just replace the motor and I purchased one from Patriot Supply for $158 even though I was aware that they say not to use them with coal stoves. The person that I spoke with said that none of the power vents from Field Controls are approved for use with coal stoves and he was surprised to find out that my two local dealers sell Alaska Stoves with these power vents. The new motor that I received has a new design with sealed bearings, so there aren't any oil holes.

Unfortunately, the performance of the motor has been diminishing over the past two weeks and now, even with the adjustment weight at the very end of its range, the damper barely moves. The only thing I can do is clean the power vent, which I did. With the old style, I could oil it and would see improvements in the air flow.

I don't know if the coal companies do anything to improve the performance of the motors in coal applications, but there definitely seems to be a difference.

I would like to hear about other people's experiences with motors from Patriot Supply.

Damn that's scary. Mine came with my '94 Stove and runs like a champ (although I'm on yr 2 with it and don't know how many hours are on the actual unit itself). I guess only time will tell.

I wouldn't go on blaming "Patriot" they are only a distributor, not the manufacturer.

I'm not blaming Patriot. From my limited interaction with them, I would highly recommend them if you're looking for products they sell. The people that I've spoke with seem to be very knowledgeable and were helpful.

Before replacing the motor, I decided to take the pipe off (between the stove and power vent) to make sure it wasn't plugged. In the past 10 years, I've only had ash accumulate the top of the stove opening going into the pipe. This time, I found that ash had settled at the power vent draft adjustment and plugged the vent. This has never happened before, so I didn't expect a problem there. So the motor is actually good and the stove is now running properly.

I spoke with a tech support rep at Alaska and he told me that they don't make any modifications to the motors they sell with their stoves. The only difference is they paid to have them UL certified for use with solid fuels. So, hopefully this new motor will last as long, or longer, than the last.

1 Tip to the longevity of the powervent motors is at the end of the season as soon as it is cool. Unplug the powervent, remove the motor assy from the end and clean and lube and apply anti corrosive to the bolts that hold the motor on. Keep the motor in a dry storage area for the summer.
