U.S. & UK HVAC Manuals & Guides

Master Index, arranged alphabetically, begins below. Also see GUIAS para Equipmiento en Mexico: bombas, plomeria, calentadores de agua, y mas.

Lennox Corporation has done a better job than some other companies in providing copies of manuals for not only the company's current product line, but also for its older equipment. But HVAC manuals can be hard to find, or expensive, even though the manufacturer's will usually gladly give a copy to a consumer or service technician who needs one.

Also see the American Boiler Manufacturers' Association found at REFERENCES for more boiler makers and their contact information.

Before paying for a furnace or boiler or air conditioner manual, see if it is already listed here or at the manufacturer's website.

If you have trouble finding a mechanical system installation or service manual, CONTACT US and we will research it for you at no charge.

Also see MANUALS for HEATING SYSTEM CONTROLS for a list of free downloadable PDF files of common heating system controls used on boilers, furnaces, heat pumps.

HVAC data tag decoding: 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

In those articles we provide documents with extensive equipment data tag decoding information, both free, and for purchase from other sources.

At REFERENCES we provide more contact information, links to current model list information, product specifications, and installation/operation manuals for each manufacturer.

Wiring diagram for Sears window air conditionre - example

Watch out: you might successfully find parts, manuals, wiring diagrams for Sears (at left), Singer or other HVAC equipment brands by searching for "Companyname Parts" online.

But keep in mind that the "Companyname Parts" provider that appears might have nothing to do with the original company, name, or brand.

It's worth a call to be sure that the part number or manual are ordering is really for the equipment that you are repairing or servicing.

And as we just noted above, usually you can get the information you need from the manufacturer, for free.

If your HVAC equipment is older and is one of the brands whose name has a complex history, and if you can determine the year of manufacture of your equipment it will assist you in tracking down which company is most likely to currently stock parts or manuals for that product.

To determine the age of your equipment, see AGE of AIR CONDITIONERS & HEAT PUMPS or AGE of HEATERS, BOILERS, FURNACES.

American Boiler Association

The American Boiler Manufacturers Association (ABMA) is the national, nonprofit trade association of commercial, institutional, industrial and electricity-generating boiler system manufacturing companies (> 400,000 Btuh heat input), dedicated to the advancement and growth of the boiler and combustion equipment industry.

Founded in 1888 by boiler manufacturers in search of safe boiler design techniques and materials, the organization today provides a common ground for information sharing and to achieve better understanding and communication between manufacturers, their customers, government and the public. 

ABMA’s community of focused interest and problem solving brings the technical and production expertise of an entire industry to bear on a range of energy and environmental policy issues.

Anthes Boilers, Furnaces & the Anthes Foundry

Anthes boilers were produced by the Anthes Foundry in Winnipeg, founded by Lawrence L. Anthes ca 1915. Lawrence Anthes' earliest patent recording was a Canadian patent No. CA 191047 for a temperature regulating device filed in 1918 and granted in 1919 (probably for the Anthes foundry).

LL Anthes along with Fred Ellis and George Pallister, under the aegis of the Anthes Foundry patented a hot air furnace as CA 376829 in 1938, and another as Canadian Patent CA 379539 in 1939.

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.

Anthes HVAC Equipment Age Decoding

Typically on an Anthes brand boiler (a 1940's vintage heating brand Anthes Imperial Limited sold in Canada (the HGB 100), the U.S. and the U.K.) there is a 6-digit, all numeric, serial number. 123456 OR an alphanumeric serial number like ABC12 that encodes the equipment age, but currently you might have to pay to obtain that detail as we explain at the links given below.

For information about de-coding the data tag on Inter City Gas (I.G.C. HVAC equipment) see the Technical Reference Guide below.

Question: How to determine the age of an Anthes boiler

2017/09/16 Tony said:

Hello, I had to give an estimate for a boiler, upon viewing the existing boiler, I was wondering the age of the boiler, could someone email me if he / she has an idea, it is an Anthes- Imperial bolier WO 14 4, thanks tonynewyork@live.ca

Reply:

Tony,

Anthes boilers were produced by the Anthes Foundry in Winnipeg, founded by Lawrence L. Anthes ca 1915.

Lawrence Anthes' earliest patent I found was a Canadian patent No. CA 191047 for a temperature regulating device filed in 1918 and granted in 1919 (probably for the Anthes foundry).

LL Anthes along with Fred Ellis and George Pallister, under the aegis of the Anthes Foundry patented a hot air furnace as CA 376829 in 1938, and another as Canadian Patent CA 379539 in 1939.

You want to look at the serial number on your boiler.

Typically on an Anthes brand boiler (a 1940's vintage heating brand Anthes Imperial Limited sold in Canada (the HGB 100), the U.S. and the U.K.) there is a 6-digit, all numeric, serial number. 123456 OR an alphanumeric serial number like ABC12

It's safe to estimate that the boiler you saw boiler is no less than 50 years old and possibly, if it's a 1940's model, we're looking at a heater that's more than 75 years old.

For Anthes and a few other heater or boiler brands that have not come up with a clear age-decoder, take a look at the brand and serial number of (apparently-original) parts attached to the boiler such as the oil burner, burner motor, circulator pump, or other controls to find a serial number that can often get us in the right ballpark.

ARCO Boilers / Furnaces

ARCO was bought by SnyderGeneral in 1984 from oil company Atlantic Richfield (ARCO) and was added to Snyder General's Climate Control unit as Arcoaire. In 1991 Arcoaire became part of Inter-City Products (name later changed to International Comfort Products). In 1999, ICP was in turn acquired by United Technologies, the parent of Carrier Corporation. - see CARRIER Air Conditioners, Boilers Furnaces

Blueray Heating Boilers & Furnaces - safety recall

See this important  BLUERAY Recall notice about older Blueray furnaces and boilers.

Later models of the Blueray heating boiler (Blueray furnaces were also manufactured) attempted to correct these safety concerns but the company did not survive its image as dangerous.

The Thermodynamics Boiler Company purchased the remains of the defunct "Blueray Systems", redesigned the heating equipment, and marketed it under several names which included the "Blueray" appellation.

Those service people "in the know" realized that the Thermodynamics version of Blueray was a different animal and did not have the same safety concerns as the original.
