TERMINATION
Vertical Terminations
The diagram below shows all allowable combinations of
straight vertical and offset to vertical vent configurations
with vertical terminations. The termination must fall within
the shaded areas on the diagram. Use the restrictor positions
indicated. Offsets may consist of two 90° elbows OR four
45° elbows. The minimum termination height is 10 feet and
the maximum is 30 feet.
NOTE: Horizontal pipe requires 1/4” rise for every 12”
of run. Offsets must remain within max and min lines.
Vertical height is measured from the bottom of stove.
Horizontal Terminations
The shaded areas in the diagram below show all allowable
combinations of vent configurations with horizontal termi
-
nations. Horizontal sections of pipe require 1/4” of rise for
every 12” of run. A second 90° or 45° elbow (in addition to
the first 90° elbow at the top of the vertical length of pipe)
is allowed as long as the overall length of the horizontal
run of pipe does not exceed those shown below. Use the
restrictor positions indicated. Note that if the termination
cap falls in the unshaded area, then no restrictor is installed
in the stove.
