Hi! New to the forum. recently purchased a Enviro Meridian pellet insert about 2 weeks ago. We are burning premium hardwood pellets. Some days it smells like smoke in my house, some days nothing. Ive tried giving it more air by adjusting the knob on the side. I run it on Low, just in setting 1 with the feed trim at 5, we really don't need more heat than that produces, dosent take much and the house is too warm. My house is just a small bungalow. I'm wondering if anyone has had this issue? I spoke to the dealer today and they will send someone to check it out. I don't see anything obvious. The gaskets all seem to be in place. When I put my nose to the top of the surround I don't smell smoke, I would think if there was a problem in the exhaust connection Id smell smoke there. I know the combustion/exhaust fan is running. Any Suggestions of other things to look at? Thank you in advance
