Installation Notes
Follow the venting tables in your fireplace manual for maximum lengths, elbows and terminations. On Kingsman power vent installations, the ZCV39/ZCV42 manual uses flex with the Z47PVA adapter kit and a one-foot section of 5/8 DV hard pipe at the power vent. 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.
