Vent Configuration: Vertical Terminations using NG


The termination must fall within the shaded area shown in the chart below.

A maximum of 3 elbows (30°, 45°, 60° or 90°) may be used. Only 1 elbow may be a horizontal elbow
(see illustration below).

Vertical terminations require the high-wind cap (58DVA-VCH).
This is considered a
horizontal elbow (it doesn't
matter whether it turns right
or left). It may be a 30°, 45°,
60°, or 90° elbow.
