Not wanting to hijack the other topic post I thought I'd start one of my own, but with all this talk of stove and stack temps it got me thinking about my Morso 3450. The manual says nothing about stove top and pipe temps for optimal running, so does anybody know where I should be running these. I use a Condar Chimgard Thermometer on the pipe, about 18 inches above the stove and try to keep the flue in the orange area (250-475) while burning. I believe the instructions with the thermometer said to place it on the pipe rather than the stove, where I guess I would expect much higher temps. Any tips or other peoples experience with these thermometers would be much appreciated - just want to be sure I'm burning at the optimal and safe range.
