Hi everyone, need some help. I installed an Englander 25pdvc in April of this year. I did not have much time to test pellet fuel till these past couple of days. I ended up buying a ton of Omalley pellets as that was all I could find at the time. Now I have been trying other brands. To make a long story short I purchased 2 bags of TSC pellets. these things are burning hot compared to the few others I have tried. The other brands temp was between 240 and 250 degrees as per temp gauge beside the door. The TSC pellets are burning around 270 and I noticed some turbulence at my chimney. I have 3 inch pipe going to 6 inch class a chimney pipe that I had used for my wood stove. Do I need to be concerned .
