I’m not sure of NJ Clinton Township code, but the partial may not meet code here. I believe it works fairly well and is a big improvement over what I replaced, a “slammer” that just dumped directly into the firebox of the fireplace. It worked, but boy did it ever produce a lot of creosote over the years. I was told that it had resulted in some “small” chimney fires too, told to me my a licensed chimney service. They were not trying to sell me anything, even though they are also a Quad dealer. I think the stub liner is much, much better. Bet it works great, and if run hot may not produce too much creosote.
