Get cleaning
Scotch brite pad, gun cleaning brushes, whatever works to get in the small spaces....
Scotch brite pad, gun cleaning brushes, whatever works to get in the small spaces....It looks like you have a good bit of baked-on fly ash or creosote on your heat exchanger tubes. I have a 1st gen Quad Castille that has the scrapers on all the heat exchanger tubes, but I see your SF only scrapes the middle 4 tubes. Any baked on ash residue is no doubt reducing your heat exchange capability, so I would go in there when the stove is cool and vacuum and scrape as much of that stuff off as you can. I use my shop vac crack tool attachment to scrape off the baked ash that the exchanger tube scrapers don't get. I've also used a dryer lint brush or similar stiff bristled brush and a screw driver to scrape in between the tubes.
