[quote author="HopWallop" date="1229459612"]The manual under General Maintenance does call for it to be removed for inspection and cleaning of the flue connector, liner and chimney. In looking at it I don't see why it would have to come all of the way out. Maybe a little so you could get the surround panel off. I am also going to let the chimney sweep take care of it. I just want to make sure he puts it back together correctly. I am wondering how often I should have it cleaned. I was ok with once a year with the fireplace, but I am burning everyday now.[/quote With a full liner I don't see why insert has to be pulled to be inspected. I never did that with my other insert....Pulling this thing out is no easy task and I can't imagine doing that on a regular basis. I'll check with my sweep and see what he say. I wonder what others with inserts here who have been using them for years would say about this...maybe a good thread for not just 550 owners.
