Wall Termination Venting
To connect the Dura-Vent GS venting system to the
Estate Fireplace flue outlet, a Dura-Vent Pipe Adaptor is
required.
A list of Dura-Vent system components is shown in Fig.
#19e.
Top Vent
A minimum 6" vertical length must be installed before
the first 90° elbow. With this minimum vertical rise, a
maximum horizontal run of 18" is permitted. For longer
horizontal runs, the vertical rise must also increase.
The rise and run must be constrained to the boundries
of the chart shown in figure #20a, c, d, & e.
A horizontal run of vent must have a 1/4" rise for every
2 ft.of run towards the termination.
Rear Vent
Refer to Figures #19a-d for allowable configurations.
Roof Termination Venting
To connect the Dura-Vent GS venting system to the
Estate Fireplace flue outlet, a Dura-Vent Pipe Adaptor is
required.
Top Vent
A minimum 4' vertical length must be installed before the
termination cap or the first 90° elbow. The total vent
length must not exceed 40'. Any combination of rise and
run may be used but must be constrained to the boundries
of the chart shown in figure #20b & c.
A horizontal run of vent must have a 1/4" rise for every
2 ft.of run towards the termination.
Rear Vent
Refer to Figures #19a-d for allowable configurations.
