18” Section of Pipe

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.

Vertical Terminations

The diagram below shows all allowable combinations of straight verti-

cal and offset to vertical vent conﬁgurations with vertical terminations.

The termination must fall within the shaded areas on the diagram. Use

the indicated restrictor positions. Offsets may consist of two 90 degree

elbows OR four 45 degree elbows. The minimum termination height is

10’ and the maximum is 30 feet.
