I have just purchased home with whitfield Profile 30 stove looks to be about 5yrs old. I have been having several problems and would like to ask some questions. When I first light the stove the flame compartment fills completely with smoke and sometimes it will puff and send smoke into the room when the flame starts. it also seems to overfill the pot and I end up with pellets in the side pockets. On low setting I get a pretty large flame almost all the way to the top of the stove. I have had it cleaned and have repleaced the gasket around the door. They charged me about $70 to replace it could they have used the wrong size I see the profile 30 has a specific size and it looks like to just buy it would be over $70 bucks. any help would be apprecieated.
