Label the exhaust and intake pipes so they are not crossed, attach them to the termination with Millpac and four screws per joint, and seal the plate to the chimney top. In New York City, gas fireplaces and inserts are installed under the NYC Fuel Gas Code by a licensed master plumber, with DOB filing where required.
