We moved our pellet stove to change the base (previous homeowners put two by fours under the mat, we put it on tile). When we moved it back it won't fire up. It's a Quadrafire Classic Bay 1200 stove. The fan will come on but it won't feed pellets and then it shuts down. I have checked all the connections, cleaned out where the auger is, and blown out the tube for the vacuum switch. I have also checked pipe that goes to the outside and it is secure. Anyone have any ideas before I pay someone to come look at it?
