Can't find replacement motor for Flame Master Furnace
I have a flame master furnace installed around 1986, the motor burnt out and cannot find a replacement, anybody know where we can order the motor? - On 2020-02-25 by Roger
Reply by (mod) - Flame Master furnace blower motor replacement
Roger
What motor is "burnt out" ?
- Oil burner motor?
- Blower fan motor?
In any case I'd bet a six-pack of Castle Danger beer that the motor on your Flame Master furnace is not unique but rather an off-the-shelf electric motor that can be replaced with a generic unit.
Pull the motor and take it to a local electrical or HVAC supplier. The only wrinkle might be if there's an unusual shaft length that needs to be matched.

How do I determine the efficiency of my 1995 Fleetline oil fired boiler? - Duncan 11/21/12
Reply:
Duncan,
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.
THEN
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.

Friedrich Residential HVAC was acquired by ARCO in the early 1980s.
The company was re-named Friedrich Climate Master Inc. in 1985, selling water source heat pumps. Friedrich was dropped from the tradename in 1987.
Friedrich HVAC products evolved into Arcoaire. The Friedrich Air Conditioning name is still used on window units & mini splits after purchase of Zoneaire from ICP.
I can't find any info on my old Zoneaire(?) a/c model #30FC0060AB serial #J875255109. The tag is unreadable.

Shown here: A 1996 model Fulton 10HP ICS-010-A steam boiler at FirstTech services cited just above.
Note that commercial steam heating equipment such as this Fulton boiler operate at much higher pressures than residential steam boilers.
This Fulton boiler runs with a maximum working presure of 150 psi.
I'm working on a commercial Fulton pulse combustion boiler model phw1000k and it runs but from time to time I'd have to reset it due to low water and it's full as can be.
Probes have been replaced along with a tune up kit and relay.
Anyone have any suggestions? Thanks in advance On 2018-02-09 by Bl -
by (mod) - Fulton pulse PHW combustion boiler won't keep running - runs out of water
BI
Since you say the boiler is "as full as it can be" - and hoping you didn't really fill the boiler up past the water level indicator at the sight glass, sounds as if you automatic water feeder is not sensing the water level properly. If the probe is perfectly clean (de-scaled), and the boiler water level is above the probe level, then the sensor itself or a sensor float may be debris-clogged.
Here is what Fulton says about their low water detection device:
The boiler is furnished with a probe type low water cutoff . No field piping is required. If the probe does not sense water, the boiler will shut down and a red indicator will be illuminated on the control panel.
Often the water sensor probe on a steam boiler is particularly prone to scale formation; if the scale isn't cleaned periodically the probe may fail to sense the presence of water in the boiler so you might get a false low-water condition.
This is a different explanation of a false visual indication of low water in a steam boiler, though I don't think this is your case.
SUDDEN DROP in SIGHT GLASS WATER LEVEL - at start or end of a heating cycle - false water line?
Here are more diagnostic suggestions:
Have you been flushing the LWCO / Water Feeder valve?
What's the brand and model water feeder equipment installed?Is the sensor placed at the right water level?
Is the sensor getting debris or scale blocked?

This sounds as if the system is overheating and being shut down by the fan limit controller.
Replace the air filter, clean the blower fan and confirm that the ductwork is not crimped or disconnected, and that there's plenty of return air, and let me know if that fixes the trouble.

I've researched your General Automatic hot water heating boiler Model L-6, looking for General Automatic Boiler manuals as well as age decoding tips.
It would be helpful if you could post (one image per comment) photos of

- the boiler's logo or ID information and any other data tags and patent numbers
and of course, do tell me the country and city of location and the age of the building where the boiler is installed.
I'll continue to research but the information above would sure be helpful.
On 2018-05-15 by (mod) - Gilbarco (or Gilbarco Veeder Root) furnace
Mike
Like you I have searched for a Gilbarco (or Gilbarco Veeder Root) furnace manual that might tell us more about decoding the model data on the furnace to figure its BTU rating - with no success though I'll continue to look.
It would help if you'd add a photo of the data tag and of any other tags or labels you can find on the furnace as well as a photo of the furnace itself. Often we can find the BTUh rating on the data tag even if it's not encoded in the unit's model number.
History of Gilbarco in a nutshell:
Gilbarco was founded in 1865 by Charles Gilbert and John Barker to market their invention that processed crude oil to provide gas used in building gas lights. Five years later their company became the Gilbert and Barker Manufacturing Company.
We can speculate about the age of your heater, if it bears a "GILBARCO" brand or label, by noting that it was in 1966 that the company changed its name to Gilbarco, Inc. and moved its corporate HQ from Springfield MA to Greensboro NC. Between 1987 and 1990 Gilbarco was acquired by GE- UK.
The company's focus was on pay-at-the-pump gas pumps. Between 1999 and 2002 the Gilbarco brand was acquired by Danaher Corp. and merged with Veeder-Root.

@aw,
Let's start with the specific model and it's manual.
Can you tell us or better, post a photo of the heater's data tag.
Proper safety control setup is critical,l too.Watch out: if you are not trained in heating system installation and wiring you could be shocked, killed, or set the building on fire.

@InspectApedia-911, I don’t have a model. I am needing the wiring from boiler to ac for the relay. This is where I’m stumped. Hardy h6. Needing to make sure it is wired from thermostat to relays. I know one goes to 7 and 8 on the relay. I have a 3 wire thermostat.
all hardy wood boilers are the same. They have a 3 wire that needs to be connected to relays. I have spent hours looking for diagrams on this. Hardy manufacturer diagram does not have what I am needing. I need to know how the relays need to be wired on a 90340 relay for the ac part without using an aqua stat.
by InspectApedia-911 (mod) - wire a hardy wood boiler to the ac and furnace
@aw,
I think the reason you may be having trouble with this wiring setup, and the reason that the manufacturers may be not providing you the detail that you ask, is that there are some serious safety and control issues in trying to coordinate multiple, different fueled heating systems.
I understand that you want to reduce the question to something very simple such as 'just tell me where to put the wires'.
But the fact is we have no information about the various pieces of equipment, fuels, and venting or even nearby construction materials for your installation.
Some very basic questions such as whether or not a flue is shared involves major safety and fire hazard questions.
So just answering someone's question who, understandably impatient, says "never mind all that, just tell me where to put the wires" leaves people who are sitting far away nervous about the safety of the installation.So what I would do in this case is to call the manufacturers technical support people directly, they can ask you questions about your installation and then offer a more technically correct and safe answer.
