Venting Routes And Components
Since it is very important that the vent 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 table showing the relationship between vertical and
horizontal side wall venting will help to determine the
various vent lengths.
The maximum horizontal run is 20 ft/6.1 m when the
vertical run is 7 ft/2.1m (Figure C). Note: 1/4” vertical rise
is required for every 12” of horizontal run.
The maximum number of 45 degree bends per side wall
installation is two (2) in the horizontal run and then you
must reduce the length of the horizontal by 18 inches for
each 45 degree bend.
The maximum vertical run is 43 ft/13.1 meters.
Special Note: For each 45 degree bend installed in the
horizontal run, the length of the horizontal run must be
reduced by 18” (45cm). This does not apply if the 45
degree bends are installed on the vertical part of the
vent system.
Example:
If according to the table, the length of the
horizontal run is 10 feet, and two 45 degree bends are
required, the horizontal run length must be reduced to 7
feet.
2 additional 90° bends or equals are allowed. The
horizontal run must be reduced by 36” per each 90°
bend, or 18” per each 45° bend.
How to Use the Horizontal Vent Table
1. Determine the height of the system and the number
of bends required.
2. Having determined the vertical distance determine
the maxi- mum horizontal section allowed.
3. Vent table has been established for 90˚
horizontal/vertical runs. With use of flex pipe distance
not having 90˚ bends will not fall into vent table
standards.
For venting to a maximum of 43ft (13.1 meters).

IMPORTANT:
Always locate the fireplace in such a way that a
minimum of offsets and/or horizontal runs are required. A
Minimum 1/4” vertical rise is required for every 12” horizontal
run.
IMPORTANT
: Minimum clearance between vent pipes and
combustible materials is1 inch (25mm).
NOTE:
The final location of the fireplace must be such that the
horizontal vent dimensions fall with- in those stated on the graph.
The Maximum Vertical vent run is 43ft. (13.1 meters).
Example A:
If the vertical dimension from the floor of the fire- place
is 6.4ft, the horizontal run to the wall flange of the vent
termination must not exceed 20ft.
