Horizontal Vent- Alternate Concentric Terminal Installation: Contact
Manufacturer's National Service Department for Kit information, see "If You Need
Service" section.
Read these instructions thoroughly and make
sure you understand all steps and procedures
before proceeding with the installation.
Determine the location for the concentric termi-
nal then make a 5 in. (12.7 cm) hole through the
exterior wall.
Disassemble the concentric terminal assembly.
• Note: The concentric terminal assembly
consists of an inner, straight vent pipe, an
outer, straight combustion air-inlet pipe, a
Wye tting and rain cap.
The concentric terminal assembly is designed to
accept 3 in. (7.6 cm) diameter pipe.
If 2 in. (5.1 cm) diameter pipe is used:
• Then either 2 in. x 3 in. (5.1 cm x 7.6 cm)
pipe increasers,
• Or ush bushings must be installed to the
vent and combustion air-inlet connections
of the terminal assembly.
• DO NOT use the concentric terminal
assembly with 4 in. (10.2 cm) vent and
combustion air-inlet systems.
From inside the building, insert the outer,
straight combustion air-inlet pipe through the
wall so that the rear of the rain cap when in-
stalled sits ush with the outside wall.
NOTICE: The concentric terminal assembly
may be reduced in length as follows:
• Measure for desired installation length then
cut the outer, straight combustion air-inlet
pipe accordingly but not less than 12 in.
(30 cm).

Complete the installation of the remainder of the
vent system and attach it to the vent connector
fitting on the water heater's blower assembly.
• Horizontal sections of the vent system
must slope downward toward the water
heater a minimum of 1/8 in. per foot
(10 mm per m).
DO NOT use unequal diameters of pipe and
fittings for the vent and combustion air-inlet
systems except as defined previously
NOTICE: The difference between the vent
and combustion air-inlet system equivalent
lengths must be no greater than 5 ft. (1.5 m).
Complete the installation of the remainder of
the combustion air-inlet system and attach it
to the combustion air-inlet connector fitting
on the water heater's combustion air-inlet tube
assembly.
Support vertical and horizontal lengths of
the vent and combustion air-inlet systems as
previously mentioned.
