Sometimes, finding your water heater model number can be tricky. But, all water heaters have a Rating Plate that lists important data such as the model and serial numbers, manufacturing company’s name, length of warranty, wattage of elements installed (on electric models), gallon capacity, input BTU rating (gas models), and more.
Rheem Water Heater Model Numbers
New Rheem water heaters have an easy to understand rating plate. It includes the manufacture date, as well as information on the size and capacity.
On older models, you can determine the age of your unit by decoding the water heater serial number. Some manufacturers, including Rheem, made it easy by incorporating the month and year built into the first 4 digits of the serial number. For instance, the picture below shows that this Rheem water heater was manufactured in December of 1991 (1291). Other manufacturers use different formats, but in a similar fashion.
Let’s decode the above rating plate: This is water heater model number 21V50-2, serial number 1291A39968, manufactured in December of 1991, 50 gallons, 36000 BTU’s per hour, and is set to work with natural gas only. The other info you see relates more to service technicians, and shouldn’t be needed by the average homeowner.
The picture below shows the entire Rheem rating plate. This 50 gallon electric tank was built in August of 1984, and came equipped with 4000 watt elements
A.O. Smith Model Numbers
AO Smith rating plates look a little different, but have all the same info. Their date decoding is a little different.
AO Smith puts the year first (1991), and the month second (07, or JULY). It’s a little harder to find the info on the AO Smith plate, but it’s all there!
American Water Heater Model Numbers
American water heater rating plate, with close up below.
American’s format puts the year first, then the week the tank was built. In this example, the tank was made in the 17th week of 1998.
Bradford White Model Numbers
The Bradford White rating plate is the most difficult to decode. To find the age of a Bradford White tank, you have to understand their coding. The year of manufacture is noted by the first letter of the serial number, the month is the second letter. The decoding is based on the following format:
Year Decoder: G = 1990; H = 1991; J = 1992; K = 1993; L= 1994; M= 1995; N= 1996; P= 1997; S= 1998; T= 1999; W= 2000; X= 2001; Y= 2002; Z=2003; A= 2004; B=2005; C=2006; D=2007
Month Decoder: A= JAN; B=FEB; C=MAR; D= APR; E=MAY; F= JUNE; G=JULY; H= AUG; J= SEPT; K=OCT; L= NOV; M= DEC.
Year Decoder: G = 1990; H = 1991; J = 1992; K = 1993; L= 1994; M= 1995; N= 1996; P= 1997; S= 1998; T= 1999; W= 2000; X= 2001; Y= 2002; Z=2003; A= 2004; B=2005; C=2006; D=2007
Month Decoder: A= JAN; B=FEB; C=MAR; D= APR; E=MAY; F= JUNE; G=JULY; H= AUG; J= SEPT; K=OCT; L= NOV; M= DEC.
The example rating plates is on a tank made in June 2002.
Above is a close up of the Bradford White rating plate. This is a 40 gallon electric water heater, model number MI40L6DS13, manufactured in June of 2002. It comes equipped with 4000 watt elements. Note the “Maximum Watts” at 4000, this means the tank was built to operate in the “non-simultaneous” mode, meaning only one element will energize at a time (standard for residential water heaters). It is designed to operate with a maximum of 150 PSI water pressure, but was tested to 300 PSI at the factory for your safety.
The FDA has identified this as a Class I recall, the most serious type of recall. Use of these devices may cause serious injuries or death.
- Recalled Product(s): Medtronic Cardiac Resynchronization Therapy with Defibrillation (CRT-Ds) and Implantable Cardiovert-Defibrillators (ICDs)
- Product Codes: NIK, LWS
- Serial Numbers: See Complete List
- Manufacturing Dates: July 13, 2013 to August 8, 2017
- Devices Recalled in the U.S.: 48 units nationwide
Device Use:
Implantable Cardioverter Defibrillators (ICDs) and Cardiac Resynchronization Therapy Defibrillators (CRT-Ds) are devices that provide pacing for slow heart rhythms, and electrical shock or pacing to stop dangerously fast heart rhythms.
ICDs and CRT-Ds are both implanted under the skin in the upper chest area with connecting insulated wires called 'leads' that go into the heart. Patients need an ICD or CRT-D if their heartbeat is too slow (bradycardia), too fast (tachycardia), or needs coordination to treat heart failure.
Reason for Recall
Medtronic is recalling certain ICDs and CRT-Ds due to a defect in the manufacturing process. This defect causes an out of specification gas mixture inside the device and may prevent the device from delivering the electrical shock needed to pace a patient’s heartbeat or revive a patient in cardiac arrest.
The delay or inability to deliver a shock to a patient in cardiac arrest or pace a patient’s heart whose heartbeat is too slow could result in serious injury and/or death.
Who is affected?
- Patients with an affected Medtronic ICD or CRT-D device
- Caregivers of patients with an affected Medtronic ICD or CRT-D device
- Health care providers treating patients with heart failure or heart rhythm problems using affected Medtronic ICD or CRT-D devices
What to Do:
On January 22 2018 Medtronic sent an Urgent Medical Device Recall notice to affected customers. The notice asked customers to:
- Consider Prophylactic device replacement for patients who have been implanted with one of the affected devices.
- Contact their Medtronic sales representative for terms and conditions for device warranties.
- Review the recall notice and ensure appropriate staff is aware of the notice.
Medtronic will offer a supplemental device warranty for affected devices.
Contact Information
Customers who have questions or need additional information or support regarding this recall should contact their local Medtronic sales representative or Medtronic Technical Services at 800-723-4636.
