Johnson Corporation filed as a Foreign for Profit Corporation in the State of Florida and is no longer active. This corporate entity was filed ... Friday, December 31, 1971 as recorded in documents filed with Florida Department of State. It is important to note that this is a foreign filing.

A foreign filing is when an existing corporate entity files in a state other than the one they originally filed in.

Please tell me the age of this Johnson Co. Heater.

On 2018-10-02 by (mod) -

I'm sorry but I'm not sure what to make of that number. It looks like a model number not a serial number. If the date of manufacture is not obvious on the data tag then off and it's and coded in the serial number.

Perhaps you could attach a photo of the boiler and in another comment a sharp photo of the data tag or tags if there are more than one.

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: Henry Furnaces & the Moncrief furnace name

Matt,
The Henry Furnace Company who made Monrief furnaces was a Medina Ohio company. IF data tags were legible you'd find a 3-digit series number (perhaps like 622) equivalent to a model, or an actual Model Number (L150) and a serial number sometimes in the format A-620-22-4-B.
With no data we can't know the age of yours, though sometimes there will be a clue of the 'at least' age by noting data on the equipment service tag or on a date written on the original instructions stuffed up in the framing overhead.
Without any information you can stil bet the Moncrief is more than 20 years old, more likely from the 1950's. The 'safe' advice is to declare a 50-year old heating furnace obsolete, and past due for replacement. A more thorough assessment by someone wanting to put off buying a new furnace would be a thorough cleaning, inspection for damage or heat exchanger leaks, tune-up, and efficiency measurement if the system was found safe and operable.

Be sure that any efficiency assessment is done after cleaning and tuning and a safety inspection.

See MONCRIEF furnaces that may be helpful. That catalogs 1950's era Moncrief heating equipment.

See HENRY FURNACES & Moncrief furnaces for historical details and the chain of owners and marketers of both Henry furnaces and Moncrief furnaces.

You will need the serial number for your heater to decode is age. The brand and model number are the starting point but they're not enough.

Above on this page you will see a link to Manuel's arranged alphabetically and there you would pick the clink that includes the letter M and there you could find your furnace brand.

I've done that for you and you could leap directly to this link

MONCRIEF furnaces

There you will see that more information is provided also linking to the heater equipment company name HENRY FURNACES

If you'll be kind enough to attach a photo of the data tag for your furnace I'll be glad to look at it directly myself.

Montgomery Ward

On 2014-11-06 by Mark Cassiday - Montgomery Ward Franklin Woodstove

I purchased a used montgomery ward franklin wood burning stove. I would like to install it in my family room. The problem is, my township inspector said it had to have a U.L. tag on it to be approved or I could not install it. How do I obtain one for this model (VMT-2105 R)? I have E-mailed U.L. and also called them to no avail. Any help would be greatly appreciated.My E-mail address is markcass@newpaths.org.

On 2014-11-06 by (mod) -

Mark,
Regrettably, if the particular wood burner that you purchased is NOT UL-listed, you would not find it practical and probably not even feasible to 'obtain a UL Listing' - since doing so requires submitting a product (or perhaps several of them) to an appropriate Underwriters Laboratory for testing and certification or 'listing'.
If the model originally had a UL Listing it should have a metal tag on the device indicating that status.
Now that I've arm-waved and speculated about all the bad news, here's what you want to do:
Go to the Underwriters Laboratories website database
http://database.ul.com
and search for your woodstove by manufacturer and model. UL will tell you if that product ever was listed.
If it was, you could print that information and give it to your astute building inspector.
I tried a search of the UL database for 'Wards' + 'VMT-2105 R' and got no hits. You might try some other variations.
