iN199 Air Intake Inlet and Exhaust Gas Outlet Pipe Connections 20
November 2021 - Revision 00
SAFETY
INSTRUCTIONS
On multiple unit installations, the air intake inlet and
exhaust gas outlet piping from each water heater must
be connected into the properly-sized common piping.
Use the table in “7.6 Intake Air Inlet and Exhaust Gas
Outlet Pipe Diameter and Length” on page 24 to
determine the diameter of the common connecting
piping between each individual water heater.
4. Determine the length and corresponding diameter for the
air inlet pipe and route the pipe to the desired termination
location.
a. For termination of the pipe to the outside, continue
installing the required pipe to a suitable outside
location. Glue all connections, making sure the joints
are sealed airtight.
b. Install suitable pipe support hangers every 4 to 5 feet,
or as local building codes require.

c. To configure the unit for power vent, insert a 3'
section of 3" pipe.
5. Determine the length and corresponding diameter for the
exhaust gas outlet pipe and route it to a suitable outside
location.
a. Glue all connections, making sure the joints are sealed
airtight.
b. Install all horizontal exhaust gas outlet piping with a
minimum 2 degree (1/4" per foot) slope back toward
the water heater. This allows any condensate that
accumulates in the exhaust gas outlet pipe to properly
drain back into the unit.
c. Install suitable pipe support hangers every 4 to 5 feet,
or as local building codes require.
SAFETY
INSTRUCTIONS
Do not connect any other appliance vents to the water
heater inlet or outlet pipes.
6. If multiple units are installed, make sure the diameter of
the connecting exhaust gas outlet pipe is properly sized
for the number of units being installed.
7.3 Two Pipe Vent System (Direct Vent)
7.3.1 Single Unit Configurations
The water heater can be directly vented without any
modification using a 3-inch diameter pipe.
The following diagrams represent some typical direct venting
configurations and are included to assist in designing the
vent system. Possible configurations are not limited to the
following diagrams.
