devices may shorten the life of the water heater and
may endanger life and property. The manufacturer
disclaims any responsibility for such loss or injury
resulting from the use of such unauthorized devices.
DOMESTIC WATER CONNECTIONS
The water connections must be installed in accordance
with all national and local plumbing codes, or any pre-
vailing standard. NEVER USE DIELECTRIC UNIONS
OR GALVANIZED STEEL FITTINGS ON ADVANTAGE
PLUS CONNECTIONS. The inlet and outlet connections
are 1" on the 45 gallon models and 1-1/2" on the 80 and
119 gallon models. On the cold inlet, install a 1" brass
tee on the 45 gallon models, or a 1-1/2" brass tee on the
80 and 119 gallon models. On the run of the 1" brass tee
install, with pipe sealant, compound a 1" brass drain cock
or it's equivalent (not supplied). Into the branch of the 1"
or 1-1/2" brass tee install a copper male adapter to match
with the copper plumbing system. For convenience, you
may install a shut off valve and a union in the cold inlet
piping to ease servicing in the future. If there is a back
flow preventer, or any type of a no return valve in the sys-
tem, then you must install an additional tee for a suitable
potable thermal expansion tank. (See section on
Expansion Tank.) In the hot outlet connection, (top left),
install a suitable adapter to match the copper tubing of
the plumbing system. A thermal trap or heat trap loop
may be installed here to provide additional energy sav-
ings and prevent thermal siphoning of domestic hot
water. A domestic hot water tempering/ anti-scald valve
should be installed into the hot water line to prevent the
maximum outlet water temperature from exceeding 125°
Fahrenheit to prevent scald injury.
SPECIAL INSTRUCTIONS FOR BOOSTER
INSTALLATIONS
All booster heaters are supplied with the "Booster
Installation" kit. In order to maintain proper temperature,
this kit must be correctly installed. The Booster kit con-
tains the following list of parts:
#01 - Nibco Tee - 1"x 1"x 1/2" (2 pcs.)
#02 - Female Adapter - 1" (2 pcs.)
#03 - Dial Thermometer (2 pcs.)
#04 - Expansion Tank - 4-1/2 Gal.
#05 - Grundfos 3 Speed Pump w/ Check Valve
#06 - Nibco 1.2" x 12" Fitting Air Chamber
#07 - Vacuum Relief Valve
#08 - Pressure Gauge - 0 - 200 PSI
#09 - Nibco Tee 712R - 1"x 1" x 3/4" (2 pcs.)
#10 - Nibco Tee 714RR - 1"x 1/2"x 1"
#11 - Nibco Tee - 1"x 1/2"x 1" Copper
#12 - Reducing Coupling
#13 - Pressure Reducing Valve
#14 - Nibco Male Adapter - 1"
See the following drawing for a typical "Booster" installa-
tion. Please note that those items marked with an aster-
isk in the drawing are not included with the Booster kit,
but are items that should be installed in a typical dish-
washer package.

The booster heater is equipped with a circulating pump to provide the
minimum water flow in the booster and maintain a uniform water tem-
perature in the tank. Depending on the physical distance from the
booster to the dishwasher, and the length of time between washes, it
may be necessary to run an empty rack to purge the supply line of
water that has cooled below 180ºF. For this reason it is best to locate
the booster as close as possible to the dishwasher. The circulator is
equipped with three speeds to increase flow rate and reduce heat
loss. Reference the "Distance" chart to determine the appropriate cir-
culator speed setting.
All piping should be installed with suitable pipe insulation to avoid
temperature loss on the re-circulation line. A minimum of 1" thick pipe
insulation is recommended. Under no circumst
ances should the
booster be installed without a circulating pump.
