See Figure 26,It is very important that the
horizontal/inclined run be maintained in a
straight (nodips),slightlyelevatedplane.The
recommended incline is approximately 1/4"
per foot (20 mm per meter) horizontal, in a
directionaway from thefireplace. The riseper
foot run ratios that are smaller are acceptable
all the way down to at or near level.
It is important to maintain the required clear-
ances to combustibles: 1" (25 mm) at all sides
for all vertical runs; and 3" (76 mm) at the
top, 1" (25 mm) at sides, and 1" (25 mm) at
the bottom for all horizontal/inclined runs.
