I had a PE Super 27 installed on Oct 30th. I haven't had any issues at all. Ive been burning seasoned hickory, apple but mostly cherry. Any questions Ive had Ive been able to find the answers to searching the forum without even asking. I have checked and cleaned the chimney 3 times so far everything is good just a tiny bit of gray ash. I have propane for heat, hot water, cooking and dryer (everything) I bought the house 1.5 ago knowing that propane was going to be way too expensive. One year of paying for propane was enough. My furnace has been turned completely off since Oct 30th. I figured I would just say thanks to everybody. I have recently read a few posts where it seems some people dont want to listen to sound advice. I have and its made my learning curve extremely short.
