Having been chastised for "whining" about my 2010 Quad 4300 ACC Step Top , here are issues I have:
-The heat shields rattle when the blower is on. Given that this is a "jacketed convection stove", operating it without the $290.00 blower is not an option. Upon removal of the heat shields, I found that a support brace had been inadequately welded and was the cause of rattling on that side of the stove (it rattles on both sides). I globbed Red RTV on both sides of the brace and it has calmed down on that side. the other side still rattles.
-The $290.00 blower squeals, chirps and itself rattles at any speed. The bearings are supposedly sealed so I can't figure out how to stop that. Oh, you should hear what it's doing at this very moment.
-I have double wall stove pipe and double wall insulated chimney pipe, along with an outside air kit. The stove is very difficult to control, although I understand this is systemic to many EPA tube stoves. I used magnetic tape to block off some of the primary and secondary air inlets which has helped some. The secondary inlet had no control/damper on it at all.
-The insides of the heat shields are rusting and I'll have to sand them and hit them with high temperature paint.
-Ash removal system: Quad specifies that the stove has to be cold before you can remove the ashes into the pan...uh, it's cold as bleep outside and the stove is being used around the clock. I picked up an Ash Dragon and it works very well.
Given the caulking, blocking off the air intakes and the need to sand and paint, if I wanted a stove that needed work, I would have bought a used one and saved some money. As for the blower, forget it, I'm not buying another. This stove will go on the market before the next heating season.
