Same people as my previous post, slightly different problem. Turns out, they hadn't cleaned the stove after 5 tons of pellets and after a total cleaning, the bridging or lack of pellet feeding is solved. However, sometimes the homeowner says that on Stove Temperature mode, auto ignition, the stove will not feed pellets and the stove will not ignite itself. After the 36 minute period, the stove gives up, as it should and blinks the failed ignition light. The only way she can get the stove to light when this happens, is to manually throw pellets in the burnpot. Then the ignitor will light those pellets and everything goes as planned. I am thinking that the problem is the low draft indicator. If the lowdraft voltage was adjusted incorrectly, or not adjusted at all (more likely) its possible for it to cause the situation described above, correct? I think they may have done a self install, because there are a few other questionable parts of the installation in my opinion. The vent is straight up, through the roof, but does not terminate more than 12" above the roof line, as it should per the manual.
