I'm looking at purchasing a used Gibraltar CFI model. If I put this coal insert into the fireplace, do I need some kind of stove pipe that runs part way up the chimney, or will it just vent out the back and up the chimney. This particular insert has a shield behind it which completely covers the opening of the fireplace.
Thanks for any answers to my questions.
If you can see bricks and mortar or blocks and mortar in the vertical run past the fireplace
, then there is no liner. Since it is outside the house, you likely will be ok but I would still bounce this off the code people or an expert installer.
I don't have any experience with inserts. Direct your questions to a stove and hearth shop. I suspect that the fireplace opening, or the chimney flue, will somehow have to be sealed air tight with a plate and also around the stove pipe penetrating that plate. The pipe will probably have to run up the flue a bit. If the chimney dimensions are huge (greater than 100 square inches) then you might not draft as well as you need to because it's a lot of space to heat up especially if it's unlined.
Have you checked to see if the chimney is clear and drafts well using a manometer?
I recommend this thread link since we are re-hashing an older thread: Do I need a stainless steel liner for my chimney?
