Outdoor Knight XL Installation & Operation Manual
Outdoor vent / air intake location:
The fl ue products discharged from the
fl ue outlet on the outdoor vent may be
very hot. Avoid touching or making other
direct contact with the fl ue gases or the
vent termination. These components are
hot and direct contact can result in burns.
ƽ WARNING
To prevent recirculation of the fl ue products into the
combustion air inlet, follow all instructions in this section.
Flue gas condensate can condense on exterior walls or on the
vent. Some discoloration or exterior building or unit surfaces
can be expected. Adjacent brick or masonry surfaces should
be protected with a rust resistant sheet metal plate.
Maintain a minimum of 24" clearance to the air inlet.
Locate the outdoor vent termination at least 48" (1.22m)
below and 48" (1.22m) horizontally from any window, door,
walkway or gravity air intake.
Locate the unit at least 10 feet (3.05m) away from any forced
inlet.
Multiple unit outdoor installations require 24" (1.22m)
clearance between each vent termination.
Clearances around outdoor installations can change with
time. Do not allow the growth of trees, shrubs or other plants
to obstruct the proper operation of the outdoor vent system.
