I agree, just need the confidence to do so. When I purchased the stove, I was told that they come once a year to do thorough cleaning. I was waiting to see how they did it so I can do it myself. In the mean time I thought I was doing a good job keeping up with the stove. I run it pretty much 24hrs a day. I need another set of hands to get the stove out and one the floor to clean. Will be done soon.
you do not need to build some froofy stand to support the stove when you pull it out.....a few 2x4's, cut to 2' long or so, stacked one on top of another to the height of the hearth would suffice.
The unit is heavy, and you will need to take care not to damage the wiring when you pull it out.
As for confidence, you need to just do it. There is no way to clean the fines chamber, the combustion fan chamber, and vent pipe without doing so. It isn't a thorough cleaning if you don't do this. There's some pretty good resources on the 'net as well to show you how.....and even if the seller says he'll come out and do it, really, you need to do this once a month, otherwise, you *might* have a dead stove due to lack of maintenance by the time they get out there, whenever that will be. Fr'instance....that left tube which was blocked would never have gotten there had the stove been adequately cared for.....now you know that, but obviously your dealer didn't tell you so...you might also take a look at page 30 and beyond in your manual...it details how to clean the unit...here is a link to your manual if you don't have one:

here is another cleaning link for you, with more pictures!:

anyhow hope this helps.....cannot stress enough how important it is to read your manual and do the required service. Without doing so, you are setting yourself up for failure, through no fault of the stove or dealer, and will likely result in an expensive service charge that could have been avoided.
