This vent system requires the installation of
two vent pipes directly to the unit, one pipe
for flue products and one for combustion air.
Both vent pipes are installed horizontally with
a sidewall termination point. The vent
connection is made directly to the top of the unit
and utilizes either the powered vent cap or inline
fan as described in the side wall venting section
