Chimney Problems.....

in THE MAIN WALL
I have a customer whose oil boiler (Weil McLain WTGO-7 7” vent) was having drafting problems. After checking the boiler it was determined to be the chimney. He called a chimney sweep and found the chimney (8” x 13”) had been lined with four inch standard smoke pipe surrounded with cement. The house underwent construction two years ago with over 7 feet added to the top of the chimney. The building contractor (the guy involved with extending the chimney) thinks his guys found the smoke pipe in the bottom half and continued the smoke pipe up to the top. Until yesterday the boiler seemed to be drafting but I have no proof as to previous tests showing the draft. A four inch wire brushing was able to remove a portion of rusted smoke pipe and re-open the chimney. This is my problem… (Other than a 4” chimney) The chimney is located in the center of the house completely surrounded by finished walls. The sweep says he cannot remove the pipe and cement without major damage to the interior. I have no place on the outside walls to place a side wall power vent. I do not feel safe with running the boiler with a 4” chimney. I though if it would fit a 4” liner with a chimney top power vent. I and stumped and would love to hear a few Ideas.

Thanks
