Flame-Master Gas Furnaces - a little information

Flamemaster gas furnace logo (C) InspecApediaWatch out: Names and who is using them can change over time: for example the name "Flamemaster" appears on other products such as sealants, coatings and packaging produced by Flamemaster in Pacoima California, US - not a heting equipment manufacturer.

The product line Flamemaster gas furnaces shared product designs with ClimateMater. ClimateMaster continues in business (in 2015) as a manufactuer of geothermal heat pump systems.

Here is what we have found of the history of Flame Master furnaces and Flame-Master furnace manua availability.

Watch out: some spoofing websites have gamed the search engines when you search for Flame-Master Furnace Manual and either load executable virus files or tell you they're giving you a Flame-Master Furnace manual but actually deliver a manual for a Kil 1825 Router. If a reader can share a Flame-Master furance manual with our other readers, contact us using the page-bottom CONTACT link. - Ed.

Launched in 2015, the Grant TechBox is exactly what its name suggests – an electronic source which stores all the Grant product technical manuals as downloads. Whether you need the installation manual for a product no longer manufactured, such as the Multipass boiler, or the technical information on a Grant Spira biomass boiler, the TechBox app is there to support engineers out in the field.

H. B. Smith Boiler Company + contact info for Smith Boilers & A.O. Smith Water Heaters

HB Smith, (Lowell Mass) beginning as a foundry in the 1800's, incorporated in 1878, made a cast iron boilers beginning before 1870 and continuing over many years. Boilers of the same size and type and even model were made over long periods and may look very much alike.

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

The H. B. Smith Company, a true pioneer in the heating industry as we know it today, was founded in the mid-1850's  by two brothers, Henry B. and Edwin Smith.  Originally manufacturing fences and other ornate iron work, the Smith brothers' manufacturing expertise turned to cast-iron heating products in 1859 when they formed an association with inventor, Samuel Gold and commenced manufacturing his patented "Gold" boiler/radiator products.

As the central heating industry grew, so did The H. B. Smith Company; and by 1879 the company was also manufacturing the "Mills" boiler patented by inventor John Mills.  A century and a half later, The H. B. Smith Company continues to manufacture a broad line of quality cast-iron boilers for both residential and commercial, industrial applications, including several models of "Mills" design.

From its humble beginning, our Company has weathered many economic highs and lows.  Down from the high of 450 employees in 1988, we currently have a workforce numbering 50+.  Our plant workers have been represented by Local 95 of  the Glass, Molders, Pottery, Plastics & Allied Workers International Union for over 100 years.  Management and Union employees work amicably together to ensure that high standards are always maintained.

HENRY Furnaces & Moncrief Furnaces

The Henry Furnace Company who made Monrief furnaces was a Medina Ohio company. Some history of the Moncrief furnace and Henry Furnace Company is revealed by a review of litigation between a wholesale and retailer of heating equipment:

The facts established by the pleadings and the evidence may be briefly noted. Plaintiff, The Henry Furnace Company, since 1943, (per some union documents, possibly 1941 or earlier) has engaged in the Cleveland area in the manufacture of furnaces bearing the trade name and label of "Moncrief Furnaces."

My understanding is that Henry Furnaces was purchased by Luxaire Inc. in turn joining York International, currently owned by Johnson Controls.

Luxaire, a Westinghouse division, purchased by York marketed along with Fraser-Johnson, also these brands: Home-Air, Moncrief,

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.

I may not have this exactly right because trying to track the history of names and brands in the HVAC industry, like the plumbing industry, is a bit like playing whack-a-mole, but the Inter-City HVACR brand, before whack-a-mole'ing over to United Technologies (cf Carrier) acquired either directly or indirectly the following product names & lines: American Air Filter, Arcoaire, Comfortmaker, McQuay, Singer, Snyder General,
