INSTALLATION

DIRECT VENT RETROFIT OF EXISTING CHIMNEY SYSTEM - An existing Class-A (wood-burning) Metal Chimney or Masonry Chimney can be converted to a direct vent system. Use one of the following chimney conversion kits listed below. Have the existing chimney system inspected by a professional prior to the conversion. If using Simpson Dura-Vent brand liner kit, see “IMPORTANT” note at the top of page 9. The chimney conversion should not be applied to the portion of the vent system that is in the room of the appliance. Use only Co-Axial direct vent pipe (4” inner pipe, 6 5/8” outer pipe as listed on page 9) from the appliance to the retro-connector into converted flue system. Adhere to all specifications shown on pages 6 and 7 regarding clearances to combustibles, vertical and hori- zontal vent length minimums and maximums, etc. Read all instructions in this manual and provided by vent manufacturer with kit care- fully before starting the installation. Failure to follow the instructions may create a fire or other safety hazard, and will void the war- ranty.
