Hi Everyone,
I had a mason build this bbq when I had my chimney rebuilt. It has 3 flues.
(1) furnace (1) indoor fireplace (1) outside bbq. Everytime I have have used the bbq I get a lot of smoke coming out the front and it seams to fill up my covered patio area and up the soffit. I smell and see smoke inside my house. Attached are some pictures of the bbq and features. Any ideas on what could be wrong or what I can do to troubleshoot.
