Yesterday I lit my stove for the first time this year and I have smoke leaking out the back.  I think a gasket may be the problem, but I am not sure.  Any suggestions?  If it is the gasket, do I have to call a pro?  Can I take the back off to find the gasket?  Is this a costly issue?  The stove is only a few years old, but the place I where I purchased it was terrible with customer service and I don't think they will be eager to help me.  Please help me!
