My Contour runs on HIGH mode only.
It runs sometimes on medium mode. I think you guys are right about CSS syndrome.
This stove for many years did run fine on medium. I have cleaned it from top to bottom and is running much better.
Also replace the vacuum switch.
If you're trouble shooting a vacuum problem do not blow an air can in the hose toward the vacuum switch. You will blow out the switch! I know this for a fact.
I plan on adjusting the pot dump plate. I believe it is a little too lose.
As these stoves get older, soot gets in the void aft of the exhaust fan and before the rear pipe coupling. This is a bear of a place to clean unless you remove the exhaust blower.
The Contour is an older model, but doesn't mean that it has CSS.
Also, the Combustion blower should be removed at least once a yr (the area you need to clean) according to the manual
As for CSS, some older Quads (Contour, 800, 1000, etc) did start up in the heat level selected (opposed to the New Quads starting in High, regardless of heat setting). But that Does Not mean that the older units wont start on Low or Medium
All the new Heatilators run just like the Older Quads. They start up in the heat setting they are on, just as the old box stoves. They start fine as does any other stove that is clean, has a good ignitor, clean vent, maintained motors and.blowers, and feed rate set correctly.
CSS is a made up term, related to this site only.
Stovers, CSS is BS IMHO....... If it 'used' to work OK, then it suddenly doesn't get CSS Syndrome. Something changed. These stoves have a lot of variables that affect how they run. Length of pellets and pellet density are often overlooked as a cause of problems. If you have the feed gate set for small pellets and you get a bag of longer pellets, suddenly you are feeding less lbs/hr and either it doesn't get enough pellets to start or the heat is less than you expected. That's just one example of how some people can blame CSS as a viable cause of problems.
