Have the chimney inspected and swept before installation and use a certified installer. New York City does not permit new wood-burning fireplaces or heaters under Local Law 38 of 2015, so confirm the rules for your building with us; we sell this insert for installations outside the five boroughs where local code allows. Book a free design consultation and we will check your fireplace, chimney and local rules before you order.
