Hi all, I recently joined the forum due to a feed problem on my pellet stove insert. It is a Whitfield Advantage manufactured in Oct 1994, according to the stamped label on the unit. The auger was not turning and I finally found the info to check the pressure switch on the combustion motor. When I disconnected the orange hose at the switch the auger turned. So, I have now determined from the info on this forum (thank you for all the info you have provided!) and other sites that the problem is the flue is clogged. The funny thing is I am convinced it is full of stink bugs. They have infested the area I live in to the point my house is covered with them in the fall, I mean hundreds if not thousands of the buggers. A friend that lives close by had a chimney full of them when she did the sweeping this fall. Anyway, my problem is I cannot figure out how to open the bottom of the clean out tee. I feel foolish asking, I have seen where the bottom is supposed to screw off but no matter what I do nothing moves. I just don't want to break anything. There is a bit of the rubber sealant in the area so I don't know if it was sealed on for good with this at install. I'm thinking there might be a screw where that black hole is at the bottom, it is covered with the rubber sealant. I can also tell the sealant has separated from the joint where the stove (combustion motor) joins the clean out tee. I have the RTV silicone sealant so I will reseal the joint. I have the stove about half way out of the fireplace, enough to open the T up and vacuum what I can out of there. What would be the best way to go about getting the flue opened up to clean out the bugs and ash?
