Enviro C-10791 - Manual (Page 17)

When planning an installation, it is necessary to select the
proper length of vent pipe for the particular requirements. The
configuration of the venting pipes depends on the locations
of walls, ceilings and studs. However, the pipes cannot be
of arbitrary length and arrangement. Because the length of
the vertical and horizontal sections dramatically affects the
burning efficiency of the fireplace, certain guidelines have
been set in the Vent Configurations section.
