I've had a Quadra-Fire 1200i (Insert) for about three years now. I've only had the controller box replaced under warranty. I'm cleaning all myself now since the dealer was charging $420. I just watched him last time a few years back and took good notes. Anyway no problems this year, but I'm sure something will come up in the future. So I have the Insert and was wondering if all the snap disc / convectional blower discussions on the 1200 stand alone apply to 1200 Insert? Any technical details that are significantly different or are they really two completely different designs?
