The installer supplies all vent pipe
material.
Combined Air Inlet Points
In most installations, the combustion air inlet
pipe will be a dedicated system with one air
inlet pipe per water heater.
Multiple air inlets may be combined to a
single common connection if the common air
inlet pipe has a cross sectional area equal to
or larger than the total area of all air inlet
pipes connected to the common air inlet pipe.
The air inlet point for multiple water heater air
inlets
must be provided with an exterior
opening which has a free area equal to or
greater than the total area of all air inlet pipes
connected to the common air inlet. This
exterior opening for combustion air
must
connect directly to the outdoors.
The total length of the combined air inlet pipe
must not exceed a maximum of 50
(15.25m) equivalent feet. Subtract 5 feet
(1.52m) for each elbow in the air inlet pipe.
Deduct the restriction in area provided by any
screens, grills or louvers installed in the
common air inlet point. These are common on
the sidewall air inlet openings. Screens, grills
or louvers installed in the common air inlet
can reduce the free area of the opening from
25% to 75% based on the materials used.
OUTDOOR INSTALLATION
Units are self venting and can be used
outdoors when installed with the optional
Outdoor Cap. This cap mounts directly to the
top of the water heater and covers the flue
outlet and combustion air inlet openings on the
jacket. No additional vent piping is required.
Maintain a minimum clearance of 3
” (76 mm)
to combustible surfaces and a minimum of 3 ”
(76 mm) clearance to the air inlet.
An outdoor unit should not be located so
that high winds can deflect off of adjacent
walls, buildings or shrubbery causing
recirculation. Recirculation of flue products
may cause operational problems, bad
combustion or damage to controls. The unit
should be located at least 3 feet (0.91m)
from any wall or vertical surface to prevent
adverse wind conditions from affecting
performance.
Multiple unit outdoor installations require
48
” (1.22m) clearance between each vent
cap. The outdoor cap must be located 4
feet (1.22m) below and 4 feet (1.22m)
horizontally from any window, door,
walkway or gravity air intake.

NOTE:
Some discoloration
to building exterior
or unit surfaces
can be expected.
Adjacent brick or
masonry surfaces
should be protected
with a rust resistant
sheet metal plate.
NOTE:
Outdoor models must
have an optional
vent cap and air inlet
shield installed.
