NYC FGC 501.15.2 Flue Passageways
The flue gas passageway shall be free of obstructions and combustible deposits and shall be cleaned if previously used for venting a solid or liquid fuel-burning appliance or fireplace. The flue liner, chimney inner wall or vent inner wall shall be continuous and shall be free of cracks, gaps, perforations or other damage or deterioration which would allow the escape of combustion products, including gases, moisture and creosote.
What Our Customers are Saying…
Upon your recommendation I recently had my oil burner chimney repaired/replaced by Guaranteed Chimney. They increased the size of the flue to seven inches from four inches. The negative draft is now five.
This company was very professional and reasonable in their pricing. I highly recommended them.
