The NV / PV (Natural Vent / Power Vent) switch
(Figure 30) on the interface board (Figure 26) is
set according to which type of evacuating vent
system is present. If the fireplace is vented with-
out the assistance of a power vent, the switch
must be set to “NV”. If using a power vent, “PV”
must be selected. Follow the instructions pro-
vided with the power vent kit for proper installa-
tion.
