I just installed basically the same pool heater a few days ago which I bought used (two years old) off a local pool installer. I was lucky to find your post, it's been very helpful since I never got any information or literature when I bought the heater. I fired it up just yesterday and so far so good, but I am experimenting on how to get the most efficient burn. Have you tried different position on the lower damper door to get more heat? Also, wondering if your burning seasoned wood or green? Any insight would be appreciated.
