POWER VENTING OVERVIEW
In the event of a vent route that is unsupported based on the Gravity Vent Tables shown in the Flare Install Manual, Flare
Fireplaces may use a power vent to accommodate any extremely long, or negative degree venting routes. The 3 power vent
options allow the fireplace to operate in vent conditions that would not be possible without the powered fan. With a power-vent
you can install a 90-elbows right off the top of the fireplace. When using the power vent system, it is critical that the vent path
remain completely sealed for the power vent system to operate. The vent length and restrictor level should be set based on
number of feet, number of elbows, and the vent termination.
The system is designed and tested with DuraVent 3x5 gasket direct vent pipes. It is critical for the safety and operation of the
system to use the DuraVent 3x5 gasket system. See the link below for a DuraVent catalog & vent parts with part numbers:
https://www.DuraVent.com/docs/product/CVS_Catalog.pdf
All three Flare Power Vent systems can be installed to include 8 elbows and run up to 100ft vent run.
-A minimum length of 12ft venting is required between the Fireplace and the PV, Flare Fireplaces sizes 30”-70”. A minimum
length of 15ft,Flare sizes 80”-100”, is required between the fireplace and the PV.
-Elbows, whether 45 or 90 degrees, do not count towards the minimum distance requirements.
-Do not install any Power Vent system if the minimum length is below listed above. The three Power Vent systems can be
installed with a maximum of 5ft vent run below the fireplace.
-Do not install any of the Flare Power Vent fans inside the fireplace cavity, as this increases the risk of overheating
-Do not snake 3x5 vent pipe within cavity to achieve minimum length, as this will lead to increased heat buildup.
