Yesterday I had my official start to the '09/'10 burning season with an all-day burn to bring my storage tanks up to temp. This was also my first real test of the inducer I installed over the summer.
I bought the inducer from Zenon at New Horizon. The price was right but my unit arrived pretty heavily damaged. It took me an hour of heating, bending, pounding and straightening to get the fan to run in the inducer without grinding on the fan housing. This was a big pain and quite disappointing for a brand new unit. I requested from New Horizon a replacement gasket for the fan mount for my "troubles" which I never received. Another disappointment.
So on to the function of the unit. During the first fire I found a ALL KINDS of spots I had apparently missed with the RTV sealant. Holy crap did this thing leak. I might as well have lit my first fire with both doors off my EKO for as much smoke as I got in the house. For the record - the inducer has a very odd ball size which doesn't lend itself to fitting snugly over existing 8" black pipe. A metric ton of RTV sealant is required to stop the smoke. And applying sealant during a burn can be fun (re: burn on forehead).
Once I stopped all of the leaking at the unit itself I moved on to inspecting my Class A pipe joints which were previously sealed with RTV after my test runs of the inducer. The inducer is able to push fly ash (and smoke) out of just about any joint during operation. Everything needs to be sealed. I was good to go here after a few more dabs of sealant.
Once I had an established fire and good draft without the inducer I decided to try her out during a mid-burn reload. I kept the bottom door closed, open bypass, turn on inducer, open upper door slowly. Initially I thought the inducer was exceeding my expectations....but I quickly realized even on full power it wouldn't keep "all" of the smoke in the upper chamber. I still had some smoke coming out the door during loading. Unfortunately, this is exactly what I bought the unit to prevent.
This morning I used the inducer during a cold start. It worked great at getting a quick fire going. I'm pretty sure the inducer cuts my cold start time in half when compared to starting without one. Very impressed with this part of the unit.
So at the end of the day I have very mixed feelings about the inducer. Since the real reason I wanted the unit was to have smoke free mid-fire reloads I can't say I'm overly pleased with it. I think the problem is that the inducer seems to suck more air through the HX tubes than it does the bypass opening. When you run it with very little wood/coals in the chamber you can see that it actually draws fire/smoke down through the nozzle. When the upper chamber is half full with wood I think the amount of air it pulls through the bypass opening is not enough to catch all the smoke.
Overall I give it a C+. For the amount of work I had to do to get this thing functioning, installed and sealed I dare say I may not have done it had I known how it performs. Here are a few photos of my install for you:
