NYC MC 801.18.2 Flue passageways

NYC DOB

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. Where an oil-fired appliance is connected to an existing masonry chimney, such chimney flue shall be repaired or relined in accordance with NFPA 31.


What Our Customers are Saying…

Just a brief note to compliment your company and its people, specifically Mike and Alberto on the very professional manner in which the repair estimate and the subsequent repair of the boiler chimney and the chimney itself was executed.

I will not hesitate to recommend Guaranteed Chimney to any of my friends who might need similar work. Thank you again for a job well done!
