NOTICE
▪ B. IMPROPER COMBUSTION
▪ C. GAS
Should overheating occur or gas supply fails to shut off, do not turn off or disconnect electrical supply to the water heating appliance.
Instead, shut off the gas supply at a location external to the appliance.
▪ D. WHEN SERVICING THE APPLIANCE
ㆍ
To avoid electric shock, disconnect electrical supply before performing maintenance.
ㆍ
To avoid severe burns, allow appliance to cool.
ㆍ
Do not use petroleum-based cleaning or sealing compounds in an appliance system. Gaskets and seals in the system may be damaged, possibly
resulting in substantial property damage.
ㆍ
Always verify proper operation after servicing the appliance.
After installation, all appliance safety devices should be tested.
DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN SUBMERGED IN WATER. Immediately call a qualied service technician. The
appliance MUST BE replaced if it has been submerged. Attempting to operate an appliance that has been submerged could create numerous
harmful conditions, such as a potential gas leakage causing a re and/or explosion, or the release of mold, bacteria, or other harmful particulates
into the air. Operating a previously submerged appliance could result in property damage, severe personal injury, or death.
NOTE: Appliance damage due to ood or submersion is considered an Act of God, and IS NOT covered under product warranty.
Do not obstruct the ow of combustion and ventilating air. Adequate air must be provided for safe operation. Failure to keep the exhaust vent and
intake pipe clear of ice, snow, or other debris could result in property damage, serious personal injury, or death.
Due to the low water content of the appliance, improper sizing of the appliance with regard to heating system load will result in excessive cycling
and accelerated component failure. Rheem DOES NOT warrant failures caused by improperly sized appliance applications. DO NOT oversize the
appliance to the system. Modular appliance installations greatly reduce the likelihood of appliance oversizing.
Be sure to disconnect electrical power before opening appliance cabinet or performing service. Label all wires while performing service to ensure
proper re-wiring of the appliance. Wiring errors can cause improper or dangerous operation. Failure to do so could result in an electrical shock,
improper appliance operation, property damage, serious personal injury, or death.
Any claims for damage or shortage in shipment must be led immediately against the transportation company by the consignee.
This appliance is certied for indoor installations only. The appliance consists of gas ignition system components which must be protected from
water (dripping, spraying, etc.) during operation and service. Carefully consider installation location and the placement of critical components
(circulators, condensate neutralizers, etc.) before installing the appliance.
This appliance provides a overheat shutdown limit. In the event the appliance water exceeds the set point of the control limit, the cutoff will trip
and the appliance will shut down. Certain local codes require additional temperature limits. In addition, certain types of systems may operate at
temperatures below the minimum set point of the limit provided with the appliance. Contact a qualied service technician for additional overheat
controls.
DO NOT allow children to operate this unit. DO NOT use this unit if it does not appear to be operating correctly. A qualied technician should
service and inspect the appliance annually.
The appliance DHW temperature is factory set to 125°F (51°C). To avoid scalding, always check the temperature of the hot water before bathing,
showering, washing, etc. DO NOT adjust the water temperature while the appliance is being used by other persons.
If the appliance is exposed to the following, do not operate until all corrective steps have been made by a qualied service technician:
1. FIRE
2. DAMAGE
3. WATER
This appliance is equipped with a three prong 120 VAC plug. It should only be plugged directly into a properly grounded three prong 120 VAC
receptacle. DO NOT remove the ground plug from the plug.
DO NOT alter or modify the appliance or appliance controls. This can be dangerous and WILL VOID the warranty.
Failure to follow these statements could result in property damage, severe personal injury, or death.
NOTE: When inquiring about service or troubleshooting, reference the model and serial numbers from the appliance rating label.
