I bought the CS on sale from TSC in Oct/19. I installed it in a brand new 960sq/ft cabin in Nov/20. It is vented with DuraVent twist lock pipe and also uses a DuraVent OAK. It has a horizontal exhaust run of approx 30” through the wall thimble and connects to clean out tee, then rises vertically approximately 36” to the exhaust tip. Pipe is sealed with RTV and I had no leaks during first startup. Within 10 minutes of startup it shut off. I tried again and same result. Went to diagnostics and realized the proof of fire switch was faulty. Simple enough, switched wires to secondary POF. Re-started stove and things were fine for maintaining fire. First weekend burn was ok, but had lazy flame and smoky glass. I used Manual mode. Second weekend I used Temp mode to see if that would work better. Heat was good, only hit setting 5 a few times until the desired temp was reached. Ok, I’m getting the hang of this. Weekend came and went and nothing major to report. Following week I planned on staying for 10 days. I had plenty of pellets (Pennington hardwood from Sam’s Club). Started fire on Friday eve and stove ran fine. Loaded with pellets until Sunday when I shut it down to clean and inspect. Slightly dirty glass and varying flame throughout run time but nothing causing concern. To remedy the dirty glass I upped exhaust voltage in stall 1 by 5 volts 80-85 and changed nothing else in order to test it. Next day was good and burn pot looked like it was relatively empty and clean. Followed plan of loading pellets and checking over next two days. All was fine. Get to Wednesday, early morning, and I got up to get a drink and the fire was huge. Pellets spilled outside of burn pot and they were lit. Flame was large and lazy. I shut it down to take a look and I discovered that the “heat shield” (see pic) appeared to have disintegrated. I cleaned out stove and found no other issues. Left cabin early to get home and contact Ardisam. Sent pics and provided them with the details mentioned above. The stove was passed it’s one year warranty, but either, because I hadn’t used it or because they have never seen this issue, they replaced the stove; which I received today. I’m happy the stove has been replaced and can’t say enough good things about the customer service experience. However, I am concerned that there may be more issues down the road. The manual provides good info, but there is a lot of subjectivity regarding pellet brand and stove adjustments. This is my first pellet stove and this issue is not what I was expecting. I will re-install the new stove and tread lightly. I have located a better quality pellet as well. Wanted to share my story and see if anyone has any ideas? Also, Ardisam said that the initial stove couldn’t be easily repaired, but at least I have something to cannibalize parts from moving forward. Thanks!
