My home is a ranch with a steel plate 1979 wood stove in a finished basement. The stovepipe goes thru the concrete foundation to an outside flue lined block chimney. I only run the stove on week ends so getting the draft started in a cold chimney was always met with a lot of smoke coming into the room and setting off the smoke alarm. My solution was to purchase a weed burning propane torch for a 20lb tank from Harbor Freight and with some adapters connected it to a disposable propane cylinder. The torch has a trigger on it to create a hot blue flame. I aim the flame into the exhaust pipe inside the stove and in a very short time the draft starts and the flame is pulled out the exhaust pipe. When I see that the draft is going, I hit my top down built fuel load with the flame and away it goes with no smoke coming into the room. I thought that the disposable cylinder would empty fast but I have used the same one for over ten fire starts. I don’t know if the newer type stoves let you get at the exhaust pipe like my old stove but maybe enough clean heat from the torch will work. This works so good for me I thought it a good tip for other cold chimney fire starters.
