Horizontal Terminations

The shaded areas in the diagram below show all allowable combinations
of vent configurations with horizontal terminations. Horizontal sections
of pipe require 1/4" of rise for every 12" of run. A second 90 degree or
45 degree elbow (in addition to the first 90 degree 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 below then no restrictor is installed in the stove.
To install the stove with pipe directly out the back (as shown in Figure
21 on Page 14), a snorkel is required for this appliance. See Page 14 for
snorkel installation instructions.
