Connect Water Heater to Water Supply

Water connecons to the tankless water heater

should follow all state and local plumbing codes.

If this is a standard installaon, refer to the Piping

Diagram for Basic Installaon.

Checklist for Plumbing

□ Purge the water line of all debris and air by

closing the hot isolaon valve and opening the

cold isolaon valve and its drain. Debris will

damage the water heater. Use a bucket or hose

if necessary.

□ Ensure that hot and cold water lines are not

crossed to the unit and are leak free.

□ Ensure that the temperature & pressure relief

valve is installed.

□ Clean the inlet water lter. Refer to the “Water

Filter Inspecon, Detecon and Cleaning” secon

in this manual for the water lter cleaning

procedure.

□ Check for proper water pressure to the water

heater. Minimum water pressure is 20 psi. Rinnai

recommends 30-50 psi for maximum

performance.

DO NOT OPERATE THIS WATER HEATER UNLESS IT IS

COMPLETELY FULL OF WATER. To prevent damage to

the appliance all air must be relieved from the system

and a hot water xture must be owing water before

the water heater is plugged in and turned on. To

ensure safe and eecve operaon of the water

heater use the following lling procedure:

To ll the water heater:

1. Ensure the drain valve located at the boom

of the tank is closed.

2. Open nearest hot water xture in the

system.

3. Open the cold supply valve to the water

heater.

4. Keep the hot water xture open unl the

tank is lled and constant ow is obtained at

the xture.

5. Check water heater connecons and

plumbing system for damage or leaks. Repair

if needed.

Filling the Water Heater

1. Use of this layout should provide a trouble free

installaon for the life of the water heater. Before

making the plumbing connecons, locate the

COLD water inlet and the HOT water outlet. These

ngs are both 3/4” N.P.T. male thread. Make

sure that the dip-tube is installed in the cold wa-

ter inlet. Install a shut-o valve close to the water

heater in the cold water line. It is recommended

that unions be installed in the cold and hot water

lines so that the water heater can be easily dis-

connected, if servicing is required.

2. When assembling the hot and cold piping, use a

good food grade of pipe joint compound, and en-

sure all ngs are ght. It is imperave that open

ame is not applied to the inlet and outlet ngs,

as heat will damage or destroy the plasc lined

ngs. This will result in premature failure of the

ngs, which is not covered by the warranty.
