Just got off the phone with Dale @ Econoburn (Dunkirk Metal Products). Even though I bought my Econoburn second-hand, he took time to answer the technical questions that I had about my used boiler and told me to call back anytime I have a question on it. Dale and Hank are very easy to talk to and I am glad that I bought an Econoburn. Just thought I would give them a little 'thank you' for their information and time.
