Minimum and maximum vent lengths, for both horizontal
and vertical installations, and air terminal locations for ei-
ther system are set out in this manual and must be ad-

Selkirk Direct Temp
and American Metal Amerivent , follow the installation

For vent systems that provide seals on the inner exhaust
flue, only the outer air intake joints must be sealed using a
red high temperature silicone (RTV). This same sealant

The maximum allowable vertical vent length is 40 feet.
For optimum flame appearance and fireplace performance,
keep the vent length and number of elbows to a minimum.
The air terminal must remain unobstructed at all times.
Examine the air terminal at least once a year to verify that it
is unobstructed and undamaged.
Horizontal runs may have a 0 inch rise per foot in all cases
using Wolf Steel or Simpson Dura-Vent rigid or flexible
venting components when venting.
For optimum performance, it is recommended that
horizontal runs have a minimum ¼ inch rise per foot when
using
Simpson Dura-Vent or Wolf Steel rigid vent com-
ponents and a minimum 1 inch rise per foot when using
Wolf Steel flexible vent components.
