I have a Englander 25-PDVC pellet stove. Tried to call factory and Email support never get through and no reply's to the Email. I bought a accurate magnetic temperature gauge and have it mounted on the top of the stove where the blower air comes out into the room. What should the max. temperature be so I will not overfire the stove? Right now I slow the pellet feed and inc. the blower speed around 200 deg. F.
