If you were starting cold and the chimney had a downdraft when you started it will do this until the heat establishes a draft heading up the chimney. When I had a restart a couple weeks back after loading the grates with cowboy coal I popped off the baro in the T and placed a hair dryer on high for a few minutes until the manometer showed a draft of about .03. Took out the hair dryer, capped the T and then I hit the coal with a torch and fired it up.morabito wrote: Is it supposed to smoke a lot when you start it for the first time? I had this huge fire cranking and there was smoke coming out from around the edges of the fire door.
