Vertical Sidewall Applications
Since it is very important that the vent-
ing system maintain its balance between
the combustion 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 deter-
mine the various dimensions allowable.
Minimum clearance between vent pipes
and combustible materials is 1”(25 mm)
on top, bottom and sides unless otherwise
noted.
When vent termination exits through foundations less
than 20” 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.
Rear Wall Vent Installations -
Flex Vent Pipe
Follow Steps 1 and 2 on Page 13.
Step 3
Install the 4” (102mm) flex vent pipe to the appliance
collars 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. 19)
Install the 7” vent pipe in the same manner as Step 2.
NOTE: There must be a 1” (25 mm) rise in a 24”
(610mm) length of flex vent.
Step 4
Assemble the flex vent to the collars on the termination
as you did on the appliance.
