Question:

I have been shopping around for a woodstove insert for my masonry fireplace. I am getting different "stories" from the local dealers when I ask them about installation. Some say I need to line the masonry chimney all the way to the top with 6" pipes. Others claim that all I need to do is to tie the damper open- put the insert in the fireplace- and it is ready to use



Answer:

Neither is totally true. Do not buy from the guys who say all you have to do is keep your damper open..they are not educated and are doing a disservice to you. The minimum job entails a 5 or 6 foot flexible tube running from the insert up to the first flue tile area of the chimney- with a sheet metal block-off plate fit into the area below the damper to seal off room air from going up the chimney. The full lining is great- and the price of around $1000-1500 is accurate- although if it is a 6" pipe- you might find it a little less. No doubt- the lining is the best job- and a Mercedes is a great car- but we can't all have what we want. If your chimney is sound- there is a good chance that the tube to the first tile area will do the job--usually around $400. installed labor and material.
