CHIMNEY PIPE
WARNING
Label part number 900599-01 must be applied
by the installer to all chimney pipe sections but
is not required on sections that will be visible
after the installation is complete. Label must
wrap around the circumference of the pipe. See
accessories, page 19 for Kit F2659.
The chimney system approved for this fireplace consists of 12", 18", 24",
36" and 48" snap-lock, double-wall pipe segments, planned for maximum
adaptability to individual site requirements. Actual lengths gained after
fitting overlaps must be taken into consideration (lineal gain) and are
given in the lineal gain chart (see Figure 10). Lineal Gain is the actual
measurable length of a part after two or more parts are connected.
