Horizontal Vent Table
To use the Horizontal Vent Table (see Table 2), determine the total vertical height of the system
and the number of bends required. Locate the value on the first column and then move across to
see the corresponding maximum allowable horizontal run.
The Horizontal Vent Table has been established for 90
o
horizontal/vertical runs. Therefore, flex
pipes that do not have 90
o
bends will not fall into this vent table relationship.

Table 2 - Horizontal Vent Table
Figure 23 - Vent configuration illustrating maximum horizontal run of 20ft when vertical run is 7ft.
NOTE: The final location of the fireplace must be such that the horizontal vent dimensions fall
within those stated on the graph. The Maximum Vertical vent run is 40ft [12.2m]. Please refer to
C
learance to
C
ombustibles
for
information.
It is recommended for
Propane Horizontal Installations
that the venting should be a minimum
of one foot vertical off the flue before the elbow on any horizontal runs of one foot or greater.
This allows for cleaner combustion and greatly reduces carboning and cleaning of glass. (Does
not apply to Back Flue models)
