Rheem heating and air conditioning manuals, parts lists, wiring diagrams for Rheem HVAC equipment:
Free downloadable manuals for Rheen & other brand Air Conditioners, Boilers, Furnaces, Heat Pumps. Here we provide free downloadable copies of installation and service manuals for heating, heat pump, and air conditioning equipment, or contact information for the manufacturers who can provide that information for nearly all major brands of HVAC equipment.
InspectAPedia tolerates no conflicts of interest. We have no relationship with advertisers, products, or services discussed at this website.

Here, along with Rheeem, we include both Rheem and Ruud brands as well as Raypak (copper tube boilers for swimming pool heating and commercial hot water heating) together because in 1959 Rheem acquired the Ruud manufacturing company.
In 2010 we found it difficult to find Rheem and Ruud gas furnace installation manuals online, and found that Rheem's website does not offer easy email or telephone contact information for consumers.

Quoting from the Rheem website this history helps understand who produces which brands of heating and cooling equipment:
Above: a Rheem up-flow furnace illustrating major parts in the heater.
Rheem is headquartered in Atlanta, Georgia. It manufactures in Fort Smith, Arkansas; Montgomery, Alabama; Oxnard, California; Acadia, Florida; and Eagan, Minnesota. All manufacturing facilities are ISO 9001 certified. Rheem operates a state-of-the-art Parts Distribution center in Randleman, NC and distribution facilities throughout the US and in Hamilton and Mississauga, Ontario, Canada.
Rheem also has an international presence in countries such as Australia, Canada, Mexico, Brazil and Singapore [and New Zealand - Ed.] . In 1987, Rheem became a wholly owned subsidiary of Paloma Industries of Nagoya, Japan, the world's largest producer of gas appliances.
In 1959, Rheem acquired Ruud Manufacturing Company, a pioneer in the water heating industry with a well-regarded product line and a distribution network throughout North America. In subsequent years, Rheem entered the heating and air conditioning market and expanded in the late 1960's and 1970's with the rapid growth of the central air conditioning industry.
In 1985, the company acquired Raypak, a leading producer of copper tube boilers used for swimming pool heating and commercial hot water supply and hydronic heating.
Rheem HVAC equipment like the indoor air handler or outdoor compressor-condenser unit is identified by a product data tag or sticker that contains information about the unit. The data tag will include two key identification fields: the product designation or identification code and the product's individual serial number.
The product designation or model identification code is a character string that provides information about the product type, features and capacity.

See additional tonnage details in this
The product serial number is a unique character string including numbers that can be decoded to give the product's age and manufacturing details.
On some Rheem or RUUD equpment the data tag includes the equipment's date of manufacture explicitly such as shown at the upper right of this RUUD air conditioner compressor/condenser unit data tag (cited below) where we see
MFD. 07/2007
Where the equipment's manufacture date is encoded we find the date of manufacture of Rheem or RUUD heating and cooling equipmet in at least five different formats depending on both when and by whom the equipment was actually manufactured, but in all cases we can find four numeric digits in the serial number that encode either
the year shown here as YY and week number shown here as WW
or the year shown as YY and month number shown as MM as seen in the following examples.

Note: these documents describe the features and give measurements and intended application for these Rheem / RUUD oil furnaces. Good luck trying to find an actual installation, operation, or service manual at ruud.com. We looked for over an hour in December 2022 with no useful results.

CAPACITOR SIZE DETERMINATION for ELECTRIC MOTORS
The MFD. data gives 07/2006 for the date of production of this unit. No RUUD data tag decoding is needed to read the equipment age.
Watch out: We paid an online "Ruud HVAC consultant $20." to tell us where to obtain a manual for a specific Rheem gas furnace model, Rheem Criterion II Plus 2 - Gas Furnace, Model RGPK 07EAMER, Serial FQ5D302 F020601344 (Installed November 2006) – unconscionable to have to do so but that’s the fact – and eleven years later we are still waiting for an answer.

Reader Question:
Where can I find a wiring diagram for a Rheem Sure Comfort php14a48j heat pump package unit. Any help is greatly appreciated.
- Ed (May 1, 2016)
Ed:
You're looking for a Rheem packaged heat pump installation manual or guide as that will have the wiring diagram.
I found this heat pump installation manual that might help you out:
Rheem HEAT PUMP INSTALLATION MANUAL [PDF]
If this wiring diagram doesn't match your Rheem Sure Comfort heat pump unit, then see the contact information for Rheem at MANUALS & PARTS GUIDES - HVAC where we also include direct links to wiring diagrams.

Need Ruud UGDA-075C-ER Wiring diagram
On 2022-09-14 by (mod) - RHEEM Model 3204-125HD Gas Fired Force Air Furnace gas valve & thermostat connections - warning: unsafe Honeywell V8243, V8280, V8292 gas valve on old Rheem Furnaces
[Click to enlarge any image]
Thanks for that added detail. Above, excerpted from the wiring diagram on the Rheem 3204-125HD gas furnace, is the wiring diagram for the Honeywell V8243, V8280 & V8292 Gas Valve.
Watch out: The U.S. Federal Register / Vol. 48, N a 56 / Tuesday, March 22, 1983 / Notices pp. 11978 & surrounding report that many of the models of this gas valve was found to be unsafe.
Your heating system's safety relies, almost certainly on a basic feature built into the gas valve - perhaps a standing pilot and thermocouple that will prevent a signal from the thermostat from opening the valve if the pilot isn't lit.
Excerpts:
18. The design inadequacies affecting
the stop mechanisms of these controls
render them defective under section 15
of the CPSA, 15 U.S.C. 2064.
26. Should an ignition source be
introduced to a volatile LP fuel/air
mixture, an explosion and fire will
occur.
These are very helpful photos, John, thank you. I'll keep them with this article series and probably add this discussion at a appropriate thermostat wiring instruction page - linking also back between this page and that.
Working together makes us smarter. Below: Installation instructions for similar gas valves for furnaces. See instructions for Honeywell and other gas valves at:
GAS BURNER & GAS VALVE CONTROLS - our library of gas burner & gas valve controls, installation & wiring Instructions where we repeat this discussion and expand it to include details about the safety hazards of the Honeywell V8243 / V8280 / V8292 control.
This one is so old there is no Control Board. I think I figured it out. Looks like a wire goes from the 24 Volt to a thermostat back to the black switch on the gas valve.
[See photos above]
Hope this helps someone.
There ought to be a control board in the furnace, perhaps in the blower compartment, onto which you'll see the thermostat wire terminals, usually marked "T" and "T"
I have a RHEEM Model 3204-125HD Gas Fired Force Air Furnace. Where does the wires for the Thermostat connect at?
It's a real old furnace that is going into my garage.
