Vertical Sidewall Applications
Since it is very important that the venting sys-
tem maintain its balance between the combus-
tion air intake and the flue gas exhaust, certain
limitations as to vent configurations apply and
must be strictly adhered to.
The Vent Graph shows the relationship between
vertical and horizontal side wall venting and will help to
determine the various dimensions allowable.
Minimum clearance between vent pipes and combus-
tible materials is 1”(25 mm) on top, bottom
and sides unless otherwise noted.
When vent termination exits through foundations
less than 0” below siding outcrop, the vent pipe
must flush up with the siding. It is always best to locate
the fireplace in such a way that minimizes 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 to the face of the
outer wall.
Horizontal plane means no vertical rise exists on this por-
tion of the vent assembly.
Rear Wall Vent Installations -
Flex Vent Pipe
Follow Steps 1 and on Page 15.
Step 3
Install the 4” (10 mm) flex vent pipe to the appliance col-
lars described in “General Information Assembling Vent
Pipes”, Page 11. 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. 1)
Install the 7” vent pipe in the same manner as Step .
NOTE:
There must be a 1” (5 mm) rise in a 4” (610mm)
length of flex vent.
Step 4
Assemble the flex vent to the collars on the termination as
you did on the appliance.
