Rheem furnace parts at InspectApedia.comHere, 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.

Rheem / Ruud Contact Information

Quoting from the Rheem website this history helps understand who produces which brands of heating and cooling equipment:

Rheem upflow furnace at InspectApedia.com

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 / Ruud HVAC Product Label Informationm

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.

Rheem / Ruud Product Designation Codes

The product designation or model identification code is a character string that provides information about the product type, features and capacity.

Rheem / Ruud Product Serial Number & equipment age

The product serial number is a unique character string including numbers that can be decoded to give the product's age and manufacturing details.

Rheem & Ruud HVAC Equipment Age Decoder

Ruud A/C compressor unit data tag (C) InspectApedia.com ThomasOn 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.

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.

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

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.

Thermostat & gas valve wiring for Rheem 3204 Gas Furnace (C) InspectApedia.com Childers

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.

On 2022-09-14 by John Childers IA-Council Bluff - old Rheem Furnace, no control board - here's the wiring diagram

Thermostat & gas valve wiring for Rheem 3204 Gas Furnace (C) InspectApedia.com Childers

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.

Hope this helps someone.

On 2022-09-14 by (mod) - find the control board

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"

On 2022-09-14 by John Childers IA-Council Bluff - where do the thermostat wire connect on an old Rheem 3204 Furnace?

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.
