SOURCE: Williams wall non-elec gas heater. Black copper wire tagged thermostat?

First make sure this is a heater set up for a remote mounted thermostat. If so, the gas valve has 3 screws labeled TH (thermostat) and TP (thermopile) that's the flame sensor with 2 wires coming off it, I don't know where the goofy name comes from. there will be one screw that has both, usually the top one. Wire accordingly. The new valves have a solenoid on the bottom. this connects to the high temp. sensor up top. It has 2 wires on it, one connects to the thermostat wire, the other goes to the screw with TH and TP. Or you can skip it and connect the wire from the back of the valve to the Th and TP screw. Make sure the thermostat wires aren't pinched somewhere, thus eliminating the thermostats control.

Blank screen sounds like a fried thermosat. Abrupt outages can affect certain types of thermostats. Make a jumper wire and jump across R and G. See if you get any action from anywhere. If a fan or compressor kicks in you know you have a burned out thermosat...

SOURCE: Wiring diagram for a Dayton thermostat

Contact Dayton on the internet for this problem. The diagram should be available on their site. Or they will give you a number for customer care. They can give you step-by-step instructions. I am a technician and this is what I would do as their are millions of wiring diagrams. Many are noy up to date.

My limited research indicates this heater is designed for USA electrical systems. That would mean single phase, 240/208 volts, 60 Hz. The drawings I reviewed shows a 2 pole, 240 volt breaker feeding each heating circuit. That means no "neutral wire" goes to the heater and therefore no 120 volts is needed. This is good. Kenya's system is single phase, 240 volts, 50 Hz. The heater should work reasonably well on the African system. Connect the power just like you would in the US.

Can I run the hot water heater with a generator


Yes.
Ordinary electric water heater can run on any voltage from any direction (excluding volt/amp ratings below what can heat element coil).

Voltages include single-phase, split phase, and 3-phase residential/commercial voltages with either 50 or 60 Hz.
http://waterheatertimer.org/How-to-wire-water-heater-for-120-Volt.html
http://waterheatertimer.org/How-to-wire-water-heater-thermostats.html#3-phase

Install line fuse.
30 amp fuse would be required to prevent wires from overheating, and eliminate fire hazard.

This information does NOT apply to energy-smart electric water heater with box on top of heater, or newer energy smart with electronics, or to hybrid water heaters, or heat pump water heaters with delicate electronic circuitry.

Why it works like this:
Ordinary electric water heater thermostats are mechanical bi-metal switches and respond to tank temperature, and are not operated by electricity.
Ordinary generic elecrtic water heater thermostats switch electricity on-off using mechanical bi-metal switch.
Heat elements are simple coil of thermal wire that gets hot when voltage is applied.
The element will get hot when power is applied.

Dayton heater mod 2yu59 is not heating up?


Need to check the low voltage circuit for 24 volts, the 480 volt to 24 volt transformer may have a circuit protection reset or fuse installed. All the 3 phase electric heaters use a low voltage control circuit for operation of relays (24 volt coils).

I just need to know what my sp250 idlearc lincoln mig welder is single phase or three phase, my gurage has three phase running in how do i wire in ,if single phase


Hi:

Your Machine is single phase, and it could be a 208/230V or a 230/460/575V depending on the model. Check what kind of voltage do you have at your garage first, before attempting to do the following:

On a three phase wiring you will have 4 wires with the following colors; green, red, white and black. If you have 208/220/230 volts available at your garage you can connect the green, white and black wires, always green being the ground cable in the middle, black and white don't matter which side you screw them in.

Before attempting to connect a 480V to the machine check machine's plaque information in the front (or back) for real voltage, because this voltage can burn the PC board of you machine. The same color sequence applies to the 480V.

Good luck.

I am working with a Dayton 2YU39. The name plates states that it has to be powered by 208 volt system. There's a 3-phase panel and a single-phase panel. The 3-pahse panel L1 to ground is 118 volts. L2 is a...


Hi,
Here's what I think but you will have to check it out...
The fan motor in the 39 heater is a 120V fan there fore it cannot be hooked to the 240 which potentially could have the high (wild) leg as one of the fan legs...
The 240V 36 unit probably has a 240v fan motor....
Now if you were to make sure that the leg that fed the motor was a 120V to ground leg then you will be okay...
Hope you understand where I was going with this...

Hello im tryin to wire a dayton model 2yu68 unit heater 208v .30 amp bbreaker with 10 awg 3 wire and simple thermostat and still wont fire up


Are you using this heater for a residential application? 208V is typically only seen in a commercial/residential setting. It would be unusual for a home to be wired in what they call 3 phase which is how a 208 voltage is obtained.

Hope this helps. I would strongly advise that you consult with an electrician as 3 phase voltage is not for the average DIY'r.

You cannot wire a three phase motor for single phase and you cannot wire a single phase motor for three phase. If you have a three phase dual voltage motor your options are 220 or 440 volts. If you have a single phase dual voltage motor your options are 120 or 240 volts. A 208 volt Hobart motor will only function correctly on 208 volts and is not dual voltage.
