Hey all! I have posted on here before several times about how my quad trekker was having issues with venting issues with a 3 inch vent. This is in a basement setting. OAK was installed and didnt seem to change much with the “dirty glass”. So it seemed the answers i got here were considered as to a light gray/light brown to white was a good burning stove. I would only achieve these results if i burned the stove hotter than what was comfortable in the finished basement room. If I didnt have it turned up my glass would get black and creosote looking. That all being said over the summer of 2021 I replaced the venting with a 4 inch since several people said they had better results with 4 inch in basement settings. OAK is still installed and I am getting same results as before. I have tried several settings on stove, changed venting, and changed to several different hard pellet brands. The only option for pellets I havent tried are pine pellets with a higher btu. So was curious if burning a hotter fire faster because the area could be to small to heat with this large stove. I have been burning the stove on high at a high temp for a continuous burn and my glass stays clean with very little clouding over last 3 days. Anything under a 75* temp the stove starts and stops and glass gets black. Have had the stove set to 80* and have the door to unfinished side open to help with even heating. Lookin for any advice and if i was unclear with details i will do my best to answer. Thanks!
