Please continue below on how to install your 3/4 Inch Tankless Water Heater Service Valve Kit:

1. Wrap the ends of the threaded water inlet & outlet on the tankless water heater, as well as the threaded end of the approved pressure relief valve (enclosed) with a minimum of 5 wraps of PTFE thread tape or another approved thread sealant.

2. Screw the pressure relief valve into the 3/4" threads opposite the wing handle on the HOT water service valve. (RED drain handle) (see Pressure Relief Valve Section for proper installation requirements)

3. Loosen the 3/4" union nut on the HOT water valve and connect to the HOT water outlet on the tankless water heater. If nut is removed, ensure that you realign the tailpiece accurately to the valve and that the black washer is

positioned such that the raised metal edge of the valve is inside the washer.

4. Align the direction of the HOT water drain to the desired position.

5. Tighten the union assembly to the HOT water valve using approximately 15 foot lbs of torque.

6. Repeat steps 3-5 for the COLD water valve. (BLUE drain handle) for connection to the COLD water inlet on the tankless water heater.

7. Connect the INLET on the COLD water valve to the MAIN SOURCE of the water supply.

8. Connect the OUTLET on the HOT water valve to the HOT WATER plumbing system.

9. Ensure that both drain valve lever handles are in the closed position (perpendicular to the drain portion of the body).

***For proper care of this approved pressure relief valve, it is recommended that the valve is manually operated once a year. In doing so, it will be necessary to take precautions with regard to the discharge of potentially scalding hot water under pressure. Ensure discharge has a place to fl ow. Contact with your body or other property may cause damage or harm.***
