WARNING! Risk of Fire! DO NOT
terminate blower vent
into an attic, crawl space, or the appliance chase. Vent
must terminate on an adjacent, interior wall.
NOTE:
The 6 in. x 5.5 in.
intake vent cover provided
with the appliance must
be used.
The
fi
replace appliance has been provided with an active
convection blower. The blower is required to keep lower
control chamber component temperatures at an ideal op-
erating temperature. The blower also provides for more
ef
fi
cient use of appliance heat by assisting the convection
air around the
fi
rebox and back into the room. A four inch
fl
exible duct kit has been provided with the appliance. One
end of the
fl
ex duct will connect to the fan bracket assembly
located in the lower control chamber. See Figure 9.5, Detail
A. The other end will terminate to an interior wall of the
house. The intake grille panel provided with the appliance
must be used. See Figure 6.2 and Figure 6.6.
Note:
The blower is essential for keeping components and
the appliance environment in safe operating temperatures.
Note:
Refer to Section 8.B if the active convection blower
is to be moved to the right side.
