Important Safety Information

To prevent damage to property and injury to the user, the icons below warn of

varying levels of risk.

Caution

Warning Ignoring this indication will cause an immediate danger of death or

In order to prevent injury or accident, wear a protective helmet, safety boots and a

lifting belt whenever necessary.

Caution

•Use only the appropriate tools and parts:

Warning Only use replacement parts manufactured by Noritz for this model as listed in the

Installation Manual Parts List for service on this unit. Use appropriate tools.

•Modi cation of the unit is prohibited:

Do not attempt to modify or alter the unit. This will cause a re hazard and a risk of

electrical shock.

•When servicing:

Warning Disconnect the power supply during maintenance and repairs to reduce the risk

of electric shock. If it is necessary to have the electricity connected during repairs,

use extreme caution not to touch parts that may cause a shock.

•Do not short circuit any safety device on this appliance:

If a safety device is not functioning properly, replace the part. Do not under any cir-

cumstances short circuit the part.

•Exhaust and gas leakage caution:

Warning Always check for leaks when installing or modifying the exhaust vent or gas piping.

2. Post-Service Checks

•Check parts for leaks:

Caution eh tr eh t ehwf osse l d r age rskae l t suahxer o, r e t aw, sagone r ae r eh tt ah tmr r i f noC service performed could have caused them.

If the unit is installed indoors, check that the flue collar and vent pipe are installed

correctly and that they are in good condition. Confirm that there are no gas, water

or exhaust leaks regardless of whether the service performed could have caused

them.

•Check for combustibles:

Caution After service or maintenance is completed, check that there are no combustibles in

the vicinity of the unit.

•Check insulation resistance:

Warning After service or maintenance is completed, measure the resistance between the

electrical wires and ground. If it is less than 10MΩ, there is a risk of electrical

shock.

•Properly reconnect the power supply:

Warning Confirm that the power supply has been reconnected properly after service or

maintenance is completed. Also confirm that there is no dust or other obstacles

that might cause an electric shock or a fire hazard.

1. Features

1. Quick Connect Multi System

•Allows the simple installation of up to 2 units linked together using a Quick Connect Cord

CCP Valve

System controller

2. Maximum Remote Controller Length (Only one remote controller can be connected.)

•Remote controller (1 unit): Cord can be extended up to 300' with 18AWG wire.

* Note: In a Quick Connect Multi-System, only one remote controller will be installed.

3. Temperature Lockout Function

•The remote controller can be set to restrict the maximum allowable temperature setting for added safety.

See "Changing Default Temperature Setting" section for details.

4. Elevation Adjustment

• The water heater can be quickly conﬁgured for installations above 2000' by simply adjusting dip switches inside

of the unit. No additional equipment or adjustments are necessary. See the "Installation Manual" for details.
