CONNECT WATER
PIPING
Hot water outlet
("HOT") is on tank
top. Cold water inlet
is on right front
bottom of 33E and
40E. On all other
models, cold water
inlet is on tank top.

Connect the water piping, being careful not to apply heat to the heater
nipples. Install dielectric unions and shut off valves on both hot and cold water
lines.
The 40E and all "C" models (example: 32EC, 51PPC) have a 1" NPT tapping locat-
ed on the front left side of the tank. This is an alternate outlet for use with combined
appliance applications. If this fitting is not used, plug it with a fitting suitable for
potable water.
A 1" NPT fitting is also located behind the drain valve on the 40E and all
"C" models. This is for use as an alternate inlet or a combined appliance return.
Your heater is shipped with a reducer in this location to mount
the drain valve.
NOTE: INDEX LINE ON INLET NIPPLE
MUST BE ALIGNED WITH ARROW ON
DECAL. HOLD INLET NIPPLE WHEN
TIGHTENING FITTINGS. ROTATING
NIPPLE COULD DRASTICALLY REDUCE
PERFORMANCE.

Note: When converting to this configu-
ration on an existing heater, visually
inspect the heater and make certain it
does not have scale buildup on the
bottom of the tank. Scale can restrict the flow
of water into the tank.
CAUTION!! Scalding injury and/or water
damage can occur from either the manual
lifting of the lever or the normal operation of the
T&P valve if it is not piped to a proper drain. If
the valve fails to flow water or reseat, call
a plumber.
Models 33E and 40E are equipped with an inlet flow divert-
er installed in the tank. Heaters equipped with this diverter
are labeled with a decal next to the inlet (shown to the left).
The purpose of this diverter is to help keep the tank bottom
free of sediment by aiding tank flushing. The index line on
the diverter nipple must be aligned with the arrow on the
decal (left) to function properly. Do not allow the diverter to
rotate out of position when tightening the inlet fittings.
