Why We Like This Product

  • This vent kit includes all components you will need to vent a current day gas or propane fireplace insert
  • INCLUDES high quality aluminum liners.  Other vent systems may use a cheaper grade liner that tear during installation.
  • 35′ liners are designed to be cut down to size to fit your chimney
  • INCLUDES HIGH WIND rain cap.  Other vent kits have standard raid caps don’t protect the fireplace in case of a high wind.

Purpose: The dual liner system is connected to both the intake and exhaust of the natural gas or propane fireplace insert.

Installation Tips: The liners come compressed and they need to be stretched out.  It is important that you start in the middle of the liner and work your way to the end, pulling them out gradually.  If you do it too quickly, the liner will not expand properly and you will be short.  The liners will be too long – simply cut off the excess.
