Horizontal Vent Termination Clearances
The horizontal vent termination must have a
minimum of 3" (76 mm) clearance to any
overhead combustible projection of 2-1/2" (64
mm) or less. See Figure 5. For projections

horizontal terminations may be located as
close as 6" (152mm) to any (non-combustible
and combustible) exterior sidewall. This dis-
tance may be decreased to 2" (51mm) for non-
combustible exterior sidewalls only, if the
SV4.5HT-2 termination is used. For additional
vent location restrictions refer to Figure 8 on
