Heating System Equipment Age - 3 Guides for Reading HVAC & Water Heater Equipment Data Tags & Serial Numbers
HVAC data tag decoding guides: For help in decoding air conditioner, boiler, furnace, heat pump, water heater data tags and determining the age, model, or specifications of that equipment, see
AGE of HEATERS, BOILERS, FURNACES [this article]
AGE of WATER HEATERS There we provide documents with extensive equipment data tag decoding information. This article series answers most questions about all types of heating systems and gives important inspection, safety, and repair advice.
We provide links to individual manufacturer's data tag decoding guides (Lennox, below), and to two excellent equipment data tag decoding books, by Scott LeMarr (online at this website) and the Carson Dunlop & Associates Ltd. Technical reference - the most extensive such document we've found.
For many heating or cooling equipment manufacturers, especially after 2000, decoding the equipment tag to obtain the age of the device is pretty easy.
Here is an example of data tag age decoding for Peerless Heating Boilers: If the boiler was manufactured from 1984 to 1999, the serial number ends in a four digit date code. “123456-1284” would be manufactured in December, 1984. If the boiler was manufactured from 2000 to present, the serial number ends in a six digit date code. “123456-200505” would be manufactured in May, 2005.

Illustration of a Warn Air Heating System Using a Gravity Furnace
Our photo (left) shows a gravity warm-air "octopus" furnace; in its earliest version these furnaces, installed in the late 1800's in the U.S. were coal fired; many were later converted to oil.
Gravity furnaces rely on natural convection (warm air rises) to deliver heat to the occupied space. There is no blower fan in the system. In their simplest design, the gravity furnace system included no ductwork whatsoever. Rather a large grate was provided in the building floor just above the furnace itself. In a multi-story house, heat rose to upper floors by passing up the stairwell or through open registers in first floor ceilings.
The gravity furnace we show at left was a more advanced design in which an "octopus" of duct work "arms" delivered heat directly to individual areas of the building.
The furnace in our photo is taking much of its "return air" from the basement - a very expensive way to heat a home. Earlier models eschewed ductwork and instead fed heat into the first floor of the building through a large central grate in the floor immediately above the furnace.
If you don't know what kind of heat your building uses, we explain how to figure out the answer at HEATING SYSTEM TYPES.
I just bought a home in California. It has a dual sided, vent less, gas floor heater.

The only name I see is " Royal Heater". there are 2 valves; one for burner, one for pilot.
You need a key to turn them. On top of the unit is a view finder cap. Inside it looks like a 3 burner pilot
. I have attached photos of it. I'm trying to find any information on it. thank you.
[This particular heater] works beautifully and has been inspected. I want to find a operator's manual so I can maintain it.
Reply: history of Royal Metal Works gas fired floor heaters in California
The Royal brand in-floor gas heaters were originally designed in California in the late 1920's - we have a patent (Publication No. US1666367 A) by Louis Clausing (Burlingame CA) assigned to the Royal Metal Works (his own company held in partnership with Max Schwartz0 describing an earlier version of the product dated 1928: "Heating device." U.S. Patent 1,666,367, issued April 17, 1928.
Your photos below illustrate the interals of this floor-wall gas heater.
That that company was Royal Metal Works, 238 Van Ness Ave, in San Francisco, CA. That patent was cited by other product patents between 1943 and 1982.
Below at left your photo shows the gas controls including main valve (left) and pilot valvce (right-hand stem). At below right you've shown the pilot flame (I think).
The company filed just three patents, two for heaters and one for metal bending:

There is presently a [different] California Royal Metal Company (in fact several of them)
Unless you object, I'll add your photos to data we have at InspectApedia and will leave you anonymous (our default) unless you let me know that you want to be identified. That may attract comment from other readers who have similar products.
I'll attach the documents of interest to this article.
Watch out: I would not assume that the heater you have is safe to use without both a thorough visual inspection and testing for gas leaks as burning LP or natural gas in a defective appliance can produce fatal carbon monoxide gas. I would suspect that your device may also lack safety features of modern gas heaters. If you are going to ignore my timid warnings then at least be sure you have working CO and smoke detectors properly located and installed.

Frequently Asked Questions (FAQs)
Question: Age of Magic Pack HVAC
how old my magic pack hvac have no idea, i have model# and serial # the is old - Charlie 10/9/11
in the references section below we include links to some serial number decoding guide books that may be able to help you pinpoint the age of your Magic Pack HVAC system - the year is coded in the serial number.
Question: Need a rating plate for a CWF Duo-Matic Forced Air Coal & Wood Furnace
I have a CWF duo matic forced air coal and wood furnace. I have a serial number but I need a rating plate number for insurance purposes and the numbers are no longer legable. How can I get this? - Jen 10/29/11
Yours is probably an Olsen Coal/Wood - Oil forced warm air system. The CWF is more likely a model number.
But I think if your equipment is old, you may be out of luck finding anyone at the present company who knows a thing about it. Just look at the brand name history given below.
You might get some help from wood heat suppliers who I found still sell spare parts for Olsen coal/wood furnaces, such as at woodmanspartsplus.com though the parts I saw looked a bit generic. You will find help with estimating BTU output of wood fired heaters and furnaces at a variety of wood heat organizations.
It's no surprise that tracking down the current company selling or servicing older HVAC equipment is difficult. Look at this example: Olsen's product line originated in the 1940's. Olsen's combination heater line was purchased by DMO Inustries (previously known as Duomatic-Olsen, then as Olsen Technology). DMO Industries manufactured two brands of furnaces, Olsen and Airco. Those were sold in 2001 to ECR International (formed in 1999) who now owns Olsen, Airco as well as the Oneida Royal furnace brands, Utica and Dunkirk boilers as well as Enviromaster International central air conditioners.
You wont' find information about any combination fuel heaters in their current product line, thouigh for Olsen products more information may be available from Olsen/Airco at Olsen/Airco Heating & Cooling Products - USA P.O. Box 4729 2201 Dwyer Ave., Utica, NY 13504, Website: www.olsenhvac.com/ Their customer service number is 866-847-6656.
Question: Determine the age of an HB Smith gas fired boiler
how can I tell the age of my gas boiler?
Reply: History of the H.B. Smith Boiler Company
Joe you gave us a model number but no serial number. Because models are manufactured over a number of years the equipment age is encoded in its serial number not its model number. Take a look on your data tag:
HB Smith boiler data tag decoding: (pattern not verified)
In the serial number the second and third digit from the left are usually the year. E.g. from Carson Dunlop's Technical Reference,
A82-2248 would translate to year of manufacture 1982
HB Smith water heater data tag decoding:
In the serial number, begining with a letter (indicating the wate heater model), the next two digits from the left indicate the year of manufacture just as the boiler serial number above.
Carson Dunlop, Associates, Toronto, have provided us with (and we recommend) Carson Dunlop Weldon & Associates' Technical Reference Guide to manufacturer's model and serial number information for heating and cooling equipment
In Canada H.B. Smith Co., Ltd. is in Ville de Boisbraid, QU, previously located in Point Clair QU. The parent company is the U.S. firm below.
In the U.S., you can locate the H. B. Smith Company, Inc.., 47 Westfield Industrial Park Road, Westfield, MA 01085, Tel: (413) 568-3148 offers this company history at their website http://www.hbsmith.com/
I have a Spencer boiler Number 6070 4 Series R550. How can I find out its date of manufacture? -Jay Levy 12/30/11
Jay, Joe, and Charlie, in addition to using the articles and books referenced above for free or cheap ways to determine the age of a heating or cooling device, you will want to note both the product name+product number or model number AND, critically, the product serial number. The name and product number help make sure you're using the right decoding procedure. The year and month or year and week of manufacture are usually coded in the heater's or air conditioner's serial number. Often in the first four digits, as our example below illustrates.
Question: how to determine the age of a Polaris Boiler Heater by American Water Heater Co.
I have a Polaris boiler heater manufatured by Amrican Water Heater Company.
Question: determine the age of a Burnham gas hot water furnace
How do I find out the age of an 80,000 BTU Burnham gas hot water
Kern we'd need the serail number not the model number to determine equipment age. In general, just to get our terminology right, usually we call hot water heating equipment a boiler and we reserve the name furnace for warm air heating systems. I know there was an exception but that's generally the case.
A typical Burhham boiler data tag will show numbers like
Model RS-112 Ser- 35044173
or Serial No. 35 048911
or Serial# 01005880
It's that serial number you want.
I am researching the first serial number decode. For the second example, after the 35 (probably model number) the next two digits 04 are month and the nect two digits 89 the year of manufacture of the unit. In the third example we're stuck again - when you've found the serial number, I'd give the company a call, give model and serial number, and just ask them. Let us know what you learn as it will assist other readers.
You can contact Burnham Corporation in Lancaster PA at their customer service number 717-481-8400 or at 888-432-8887.
Question: American Standard Heater Age? Sunbeam?
sunbeam/american standard model sl 85, any info as far as date and age? - Magic Mike 11/4/12
I was not sure if you meant Sunbeam water heaters or American Standard water heaters.
Information on Sunbeam water heaters is at http://www.sunbeam.com - or it would be if their website page links worked. The water heaters I found under that name were little portable devices not home water heaters.
This may help: Standard Water Heaters are is not a simple brand name I could find, except tracing to A.O. Smith. If it's an A.O. Smith product the serial number contains the date encoded as follows:
xxxYY-xM- x xxx
where YY is year and M is month beginning with A= January etc.
Question: Where can I get a circuit board for my Homart electric Furnace?
Need a circuit board for a Homart electric furnace part # R43800R6 where can i find one - Wade 10/11/12
Wade, you can obtain Homart heater parts from Sears Parts Dirct.
Question: How do I determine the efficiency of my 1995 Fleetline Oil Fired Boiler?
How do I determine the efficiency of my 1995 Fleetline oil fired boiler? - Duncan 11/21/12
The heating service tech (not you) should do the following:
Clean the system completely, including boiler, flue vent connector, and if needed, chimney Assure proper combustion air source Adjust the system to factory spec: oil pressure, draft, burner nozzle, electrodes, etc.
the tech will measure the stack temperature at the breech, the CO2 level.
The combination of CO2 level and temperature allow anyone to read a chart of combustion efficiency of the unit in that condition.
Just looking up a spec somewhere tells you little about how your system is actually performing unless you take the steps above.

Question: Looking for age of an American Standfard Furnace
Looking for the age of an American Standard furnace
American Standard stopped making oil and gas furnaces in March 1968.
American Standard Boiler Serial Number Decoder:
In older serial numbers using a letter followed by two digits such as C73, the year is the two numeric digits.
In newer serial numbers such as 71B03311 I'm not sure but I'd guess the year is the first two digits (71)
You can contact American Standard to ask: telephone 800-241-4102.
Question: where do I get a part for a squirrrell cage furnace blower fan

Question: how to determine the age of a Moncrief furnace made by Henry Furnace Company
I am trying to determine the age of a Moncrief furnace made by the Henry Furnace Company Model L-95 Series 4. There is no serial #. It is maroon with chrome trim - Matt Falk Aire Serv - 3/29/2013
Reply: History of Henry Furnaces & the Moncrief furnace name
Be sure that any efficiency assessment is done after cleaning and tuning and a safety inspection.
Some history of the Moncrief furnace and Henry Furnace Company are in litigation between a wholesale and retailer of heating equipment:
My understanding is that Henry Furnaces was purchased by Luxaire Inc. in turn joining York International, currently owned by Johnson Controls.
Some of the Moncrief furnaces are operated by gas, others by oil, and there are various models in different price ranges. Plaintiff has been the only manufacturer of Moncrief furnaces in this area since 1943, when it acquired by purchase the plant, patents and all other rights of The Henry Furnace & Foundry Company, which latter company together with its various predecessors, Henry & Scheible Company,
The T. E. Henry Furnace Company and Henry Miller Foundry Company, had manufactured at least since 1905 a furnace similarly known in the trade as a Moncrief furnace. The Henry Furnace & Foundry Company, and its immediate predecessor, The T. E. Henry Furnace Company, prior to the acquisition of its plant and assets by plaintiff, had sold its product, the Moncrief furnace, throughout the United States, with the exception of the states of Georgia, Florida, North Carolina and South Carolina.
Under a consent decree entered into on September 30, 1914, The T. E. Henry Furnace Company and one S. P. Moncrief, in a law suit in a Georgia court, had provided that S. P. Moncrief and his associates should be entitled to the exclusive use of the trade name, "Moncrief," in the four states mentioned; that in the states of Alabama and Mississippi the said Moncrief and The T. E. Henry Furnace Company should be entitled to use the trade name, "Moncrief," in common; and that The T. E. Henry Furnace Company, its successors and assigns should be entitled to the exclusive use of the trade name, "Moncrief," on furnaces sold in all other states of the United States and in foreign countries. (Plaintiff's exhibit 26.) It should be added that there is testimony in the record that in Dallas, Texas, a company under the name of Moncrief Furnace & Manufacturing Company at the present time is engaged in selling a furnace known as the M.F.C. Deluxe but its field appears definitely limited to that state.
Question: find the manual for an Anthes Intercity Furnace
I’m looking for help in finding a specification plate or manual for a Anthes intercity finance from 1974. Yesterday I had a tech come to the house to clean the furnace. The tech tagged the furnace because the specification plate was missing and I can’t locate the furnace manual from 1974. I now have 45 days to either provide the furnace manual or have a new furnace installed. If by the 45th day I haven’t they will shut off the gas. Any ideas how I can get my hands on a specification plate or furnace manual from a Anthes intercity finance from 1974? - A.G. 9/18/2013
Reply: History of Inter City Gas & Its Furnace Brands: Anthes, Bullochs, Furnasman,
My understanding from reading several historical notes & reports on furnace history is that Intercity Furnace (Inter City Gas Co., Winnipeg, Canada produced Anthes, Bullochs, & Furnasman equipment) was renamed as International Comfort Products (ICP) that was in turn purchased by United Technologies in 1999. Note 1
The Anthes Intercity furnace line was produced at least from the 1950's through the 1970's. In 1980 Intercity also produced an early condensing furnace - the Ultimate - that we've read did not perform well. Note 2
You will find some websites online offering to sell parts for the Anthes Intercity Furnace under the new ICP brand. I'd try that approach to finding a manual; you may find someone who has one and can prepare a PDF - sorry but we don't have that manual ourselves or I'd post it for you. Here are some Anthes Intercity Furnace links that might help:

Question: age of an Olsen Furnace Serial 34470HTRL
(Jan 23, 2014) Anonymous said:
can you tell me how old my olsen furnace is. serial 34470HTRL
Referring to Carson Dunlop Associates Technical Reference Guide for Olsen Furnaces (www.olsenhvac.com) the key is the "HTRL" in the serial number.
I'm guessing it's a 1996 furnace based on the following explanation:
In one type of Olsen the year is in the 3rd letter - but the "R" in your serial does not translate - or if it does this unit was built after year "N" which was 1992/3. If we keep counting and guess Olsen kept the same encoding "O"= 1993/4 "P" = 1994/5 "Q"= 1995/6 and "R" would date from 1996/7 model year.
Thank you so much. There was another number FBL 17327E but the first number I listed was clearly marked as the serial number. Not sure if the FBL17327E was the model, or if it helps in any way. Thanks again for your help.
Question: information on an oudoor-installed Sterling woodstove
(Feb 10, 2014) Kari hinkle said:
Hello, I am looking for information on a outside Sterling woodstove. We purchased it with our house about 10 years ago. It runs the hot water to our home. unfortunately I am unable to find any identification numbers etc on it. it has Sterling and a phone number written on the front. I tried the number and it is nothing to do with sterling co anymore. I am running into dead ends and was wondering if anyone cld help . thanks in advance
Kari, I too had trouble finding useful information about Sterling brand woodstoves. What would make sense would be to ask for a prompt safety inspection by your local fire department and/or wood stove installer. When the original company who made a woodstove or in your case a wood-fired water heater has disappeared, a first step in getting help is to try to find who installed the stove locally. Of course that person may be gone too
Watch out: an immediate safety concern that prompts my suggestion for a fire department inspection is the risk of improper safety controls (such as pressure relief valves) or improper or unsafe chimney & venting on a decade-old wood fired hot water heating appliance. You don't want to risk an equipment explosion nor a chimney fire.
(Apr 2, 2014) Don Norman said:
To add emphasis to Dan's comments, owners will occasionally burn EVERYTHING in their wood stove or, especially, their wood furnace. Creosote accumulates quickly on the flue interior and has been the cause of many flue fires. Some years ago I inspected a home for a buyer that had installed a wood furnace in his home the year before. He had a flue fire at his wood furance that caught his house on fire. He, his wife and dogs got out and watched as their home burned to the ground. They lost everything including their vehicles. Just a word of warning.
Thanks Don you're right on about that and I appreciate the addition as will other readers.
Woodstoves are not garbage incinerators. In another case I inspected a woodstove with unsafe fire clearance distances from wood walls; the owner knew it was unsafe and had avoided burning the house down by making only tiny low-heat fires in the wood-stove - at least that was his explanation. We could hardly expect the new owner or future occupants to do something special. And none of them had considered the effects of pyrolysis, lowering the ignition point of nearby combustibles. That can explain a fire that occurs when people think they were doing "... nothing different than before". What's different may include creosote, chimney clogs, lowered combustion point of nearby substances and a host of other hazards that are perhaps less obvious to normal people.
Question: Manuals & parts sources for Sears Homart Gas Furnace
8/8/2014 Diego said:
I have a Homart gas floor furnace with model no. 133-6350. I am trying to find a copy of an owner's manual or the date of manufacture. I found a building permit for it, but it is hard to read. Thanks for your help.
Homart gas furnaces were a Sears & Roebuck brand manufactured by Dornback Hardware & Plumbing for Sears and distributed about three decades beginning in the 1940's. I"m doubtful you'd find manuals or parts from the present Dornback Furnace Co. as furnacecompare [dot] com and other sources point out that the Dornback brand was purchased by Adams Mfg. in 1992 - that brand continues but in essence it's a newer product line.
You may be able to obtain a manual as well as parts from Sears Direct parts supply at searspartsdirect.com - or give Sears Parts Direct a call at 1-800-252-1698
