Follow Steps 1 and on Page 16.
Install the 4” (10 mm) flex vent pipe to the appliance col-
lars described in “General Information Assembling Vent
Pipes”, Page 13. If the installation requires a 45° angle,
grasp the vent pipe close to the appliance collar and bend
to 45°. DO NOT exceed 45°. Figure 20
Install the 7” vent pipe in the same manner as Step .
There must be a 1/” (13 mm) rise in a 1” (305
mm) length of flex vent.
Assemble the flex vent to the collars on the termination as
you did on the appliance.

For all top vent installations where a 90° elbow is
the first pipe piece towards a sidewall termination (up and
out), an open-center ringed flue restrictor, part #69D3006
must be installed onto the top edge of the firebox flue
adapter. To create this open-center restrictor, twist and
break off the center rib of the supplied flue restrictor. The
installed part should appear similar to that show n in Fig-
ure 22.
The Vent Graph, showing the relationship between verti-
cal and horizontal side wall venting, will help to determine
the various dimensions allowable.
When vent termination exits through foundations less
than 0” (508 mm) below siding outcrop, the vent pipe
must flush up with the siding.
It is best to locate the fireplace in such a way that mini-
mizes the number of offsets and horizontal vent length.
The horizontal vent run refers to the total length of vent
pipe from the flue collar of the fireplace (or the top of the
Transition Elbow) to the face of the outer wall.
Horizontal plane means no vertical rise exists on this por-
tion of the vent assembly.
