Normally I would not use a cord and plug to connect a water heater. What do the instructions say?

This si a steam generator for bathroom, someone, that I am dealing with, posted this as a good installation. The cord is resting on the steam pipe and there are openings around the yellow conductor and copper pipes in the walls (fire penetration). Maybe I am too picky

400.10(A)(6) or(8) would be my questionable areas. IDK if steam generators need frequent interchange or ready removal for maintenance and repair. I would think not, but maybe so. The upper pipe fittings would seem to indicate easy removal but not so the bottom ones. AHJ call.

The rest would not be my concern as an electrician.

Most walls in a residence arent fire rated. A piece of insulation on the steam pipe would keep the cord safe.

what is that yellow cord/cable?

It is not obvious to me which one of the pipes is the steam exit. If I had to guess, I would say the upper one.

Also, what is the small pipe w/ the SS flex covered connection?
 
Actually the bottom pipe comes right apart. Those are Sharkbite or equivalent connectors. Just use the proper tool, or a Crescent (or any brand adjustable wrench) wrench to press on the plastic collar and the copper pipe slides right out. Also used for CPVC, PEX and PB, any pipe that is copper tube sized.

We use them at work for building prototype systems. Assemble, test, disassemble, store, assemble, test etc. Have not had one fail yet. Wonderful. Just not rated for behind wall (concealed) use.

I installed that same unit in an attic, exactly the same way, though I turned the receptacle 180 degrees so the cord went down. That's the way the instructions said to wire it. No inspection issues.

Seems like a waste of what appears to be bedroom space, but that's for the realty agent to decide :)

So that power cord comes with the unit? I would expect this kind of unit to be required to be hard wired.

I know nothing about "steam generators" other then a couple industrial "boilers" that make this thing look like a toy:) Does that mean the lower copper tubing is a condensate return? If so there must be a pump somewhere to push it back and probably a check valve so steam pressure doesn't cause flow the wrong direction?

I know less or equal to you.

Yep, that's the only one with the shutoff valve, so that would be the inlet. Most likely the steam outlet is the copper pipe on top, the copper pipe on the bottom would most likely be the emergency blow-off pipe, just like on any water heater. I doubt that's a heat concern for the incoming cable, because if that blow-off valve activates, you are already in an emergency situation and there is likely something in the circuitry that will shut down the power if that valve pops.

Yes, it comes with a 4 wire 50amp male cord connection. Hard wired would require a disconnect, so this is probably cheaper for the customer.

There was no steam return line on the one I installed. Steam is piped into a shower stall via an open outlet, similar to a bathtub over flow (pointing down). I'm guessing this unit feeds two of these outlets, hence the two copper pipes. As mentioned, the flex line is the water supply, the other the TP valve. When the unit is turned on via the remote control, the unit starts making steam. It turns off either manually or by timer.

Pretty nice unit.

Again I don't know anything about these units, but chances of the lower pipe being for steam doesn't seem all that good. I could see it being a condensate drain since there is no condensate return.
