A combustion blower is used to extract the combustion
gases from the firebox. This causes a negative pressure
in the firebox and a positive pressure in the venting
system. The longer the vent pipe and more elbows used
in the system, the greater the flow resistance.

*Long runs of flex or PL vent pipe installed directly
vertical from the flue stub may require more frequent
cleaning due to fly ash falling off inside and collecting
directly above the combustion blower outlet.
Any use of horizontal venting will require more frequent
cleaning. It is the responsibility of the installer to make
sure the entire flue configuration is accessible for
cleaning.
Stainless steel flex vent is only allowed for use in
masonry fireplaces and chimneys or in factory built
wood burning fireplace installations when used as a
liner for a class A metal chimney. All pellet vent pipe
must be secured together by means provided by pipe
manufacturer. The vent pipe must be secured to the
appliance flue collar with a minimum of three screws.
It is also recommended that you seal all vent pipe oints
with high temperature silicone.
