Horizontal vent sections within enclosures require a minimum clearance of 6"(152mm) at the top of the vent pipe.
Vertical vent sections: A minimum of 1" (25mm) all around the vent pipe on all vertical runs to combustibles is required
except for clearances in appliances enclosures. Vertical vent sections within enclosures require a minimum clearance of

note:
The L series requires a minimum enclosure height of 73" (185.4cm) measured from the bottom of the appliance.
For temperature requirements, this area must be left unobstructed. Some venting configurations that require
more vertical rise will require a larger enclosure to provide minimum vertical clearance between vent pipes and
combustibles. It is also recommended that the enclosure be ventilated at the top and bottom to circulate the
hot air.
