Using oval pipe to get past an obstruction

If a situation arises that obstructs the
CoolSmart flex vent runs (such as
getting past a minimum sideways
vent) you may transition the 5" flex
vent to a ridged nominal 6" oval pipe
to get past the obstruction. Transition
back to the 5" round flex and continue
to the manifold.
The adapters and ridged pipe should
be factory ovalized, not field ovalized.
NOTE: All clearances to combustibles
must be maintained.
