Follow Steps 1 and 2 on Page 16.
Step 3
Install the 4" (102 mm) flex vent pipe to the appliance
collars described in "General Information Assembling
Vent Pipes", Page 12. If the installation requires a 45°
angle, grasp the vent pipe close to the appliance collar
and bend to 45°. DO NOT exceed 45°. (Fig. 24)
Install the 7" vent pipe in the same manner as Step 2.

NOTE: There must be a 1/2" (13 mm) rise in a 12" (305
mm) length of flex vent. Minimum rise for any installa-
tion is 1" (25 mm).
Step 4
Assemble the flex vent to the collars on the termination

Vertical Sidewall Application
Since it is very important that the venting system
FP1472
maintain its balance between the combustion air
rise in length
intake and the flue gas exhaust, certain limitations
4/04 djt
as to vent configurations apply and must be strictly
adhered to.
The Vent Graph, showing the relationship between ver-
tical and horizontal side wall venting, will help to deter-
mine the various dimensions allowable.
Minimum clearance between vent pipes and com-
bustible materials is 1" (25 mm) on top, bottom and
sides unless otherwise noted.
When vent termination exits through foundations less
than 20" (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
portion of the vent assembly.
When installing the appliance as a rear
vent unit, the 90° or 45° Transition Elbow
attached directly to the rear of the unit is
NOT INCLUDED in the following criteria
and calculations, and unless specifically
mentioned should be ignored when calcu-
lating venting layouts.
