I got this last night.
It is the first Email correspondence I received on the subject.
Steve,
I apologize for the delayed reply as I’ve been working with the customer you referenced below from Walton’s website and his name is also Steve….in my mind, I had blended you both together. While we’ve got the other Steve taken care of I again apologize as I realize your inquiry has been idle.
We have not ever heard of this happening and we’ve had the PK in existence for almost 40 years with literally thousands of them in the field. There have been 3 instances where the smoker sides buckled when pellets were used…twice by consumers and once by our testing, but never before with sawdust. Pellets or wood chunks can absorb a great amount of heat and if ember is not created, you can get pressure to build up and once the temp gets high enough, along with the wrong mix of air flow, you get that massive ignition/combustion and pressure release. That’s why we over-mention the use of only sawdust for smoke within the first 4 pages of the manual.
We are having that unit brought back to our facility but there will be limited testing we can do on it. The customer is adamant that he only had sawdust in the smoke pan, so we can only assume that he got very high heat on the element without an ember starting and once temps got to that high enough point, airflow caused that ignition and release of pressure. But he also mentioned that this occurred in under 2 minutes and it would be very difficult to get that type of pressure to build up that quickly. We may never fully know the root cause of this. For my personal use, I do “slightly” moisten the sawdust when I’m smoking. It gives me just a slight amount of humidity in the chamber which is great for smoke distribution to the product when smoking. That being said, there are plenty out there who do not moisten the sawdust.
I also use my index finger and create a dimple in the center of the sawdust….the center of the pan is the hottest in smoke setting (625 low watt setting) and that allows oxygen to the wood…wood to the heat…to give me quickest/most thorough smoke. I hope that made sense, but if you have any questions, do not hesitate to reach out to me directly. I’d be happy to help where I can.
Thanks for reaching out to us and I hope your move forward with your Pro Smoker plan……you will absolutely love it.
