Partially insert the water heater into the opening and connect both Hot and Cold water lines to
the appropriate ½”NPT fittings. Connections can be made using PEX swivel nut adaptors with
NPS straight threads and a cone seal or with a standard ½”FPT nut. The PEX swivel nuts require
only hand tightening. (Figure 2, page 6).
Connect the gas to the 3/8” LP Gas compression fitting on the back of the Water Heater (Figure
2).
Use two wrenches to tighten the compression fitting to avoid damaging the unit
.
Use additional caulking if needed to complete a permanent seal of the gas line with the housing.

PRODUCT DAMAGE!
• Excessive torque will damage the Cold Water and Hot Water Inlets.
DO NOT over tighten.
IMPORTANT! CRITICAL INSTALLATION
• DO NOT cut any wires.
• The length of the external wires, those wires extending beyond the strain relief
from the rear of the housing (Figure 2), must NOT be shortened for any reason.
Shortening these wires will prevent the removal of the Control Housing during
servicing and/or testing.
