MaKing Water cOnnectiOnS
A. Water connections are made at the rear of the water heater. Refer to Figure 4. Connect the hot and cold water lines to
the 1/2” female pipe fitting provided on rear of tank. These fittings are marked “HOT” and
“COLD”. NOTE : Inside each fitting is a plastic fill tube. Its purpose is to enhance water
circulation. DO NOT REMOVE PLASTIC FILL TUBE.
IMPORTANT: Use a pipe thread compound suitable for potable water or pipe thread
tape on all connections to assure they will not leak.
B. Fill tank with water. Open both hot and cold water faucets to expel air from tank. When
tank is filled and water flows from faucets, close both faucets and check all connections
for leaks.
CAUTION: If you use air pressure to check for leaks, the pressure must not exceed 30
PSI.
NOTE: After leak testing, drain water from tank.
MaKing gaS
cOnnectiOnS
A. Connect a 3/8” gas supply line to the 3/8 flare fitting at gas
valve located in the control housing. When making the gas
connection, hold the gas fitting on the valve with a wrench
when tightening the flare nut. Failure to hold fitting secure
could result in a gas leak due to fitting being damaged.
NOTE: It will be necessary to remove the grommet from
the control housing, make the gas connection at the valve,
then reinstall grommet.
B. Turn on gas and check all fittings and connections for leaks,
using a soap and water solution. Correct even the slightest
leak immediately.

MaKing electrical cOnnectiOnS
A. Refer to Figure 2 (on page 8), for location of A.C. and D.C. junction box on specific models. All A.C. connections must
be inside junction box.
B. The electrical connections must be made in accordance with local codes and regulations. In the absence of local codes
and regulations, refer back to the installation and operation manual.
C . Be sure the switch for the electric element is “OFF” and that the water heater is filled with water before powering
element. Failure to do so will result in BURN-OUT of the electric element.
NOTE: Check rating plate and wiring diagram (Figure 6, 7, 8, 9, 10, 11) before proceeding. Install a fused safety
switch or circuit breaker of adequate capacity between heater and electrical power source. Attach the black and
white wires from the fused switch or breaker to corresponding colored wires in heater junction box. A wire from a
well grounded source must be attached to the green nut in the junction box.
