Re: Igniter for Instant HW heater

That's just it. Unless I'm way off base (hey, it happens all the time) it seems that even if the water heater was intended and even listed with a cord, 422.16 seems to require that it still has to be direct-wired if the mechanical is permanent.

I just am not seeing another way to read this, as much as I'd like to. :)
 
Re: Igniter for Instant HW heater

A water heater may not be readily removable (or whatever it says) to an electrician, but I'm sure a plumber could get it disconnected from the plumbing in nothing flat.

edit: george, you mean the heater was installed in the middle of a threaded system with no unions or flex pipe??? I would be shocked to see that. In the middle of a threaded system would be the only way it would not be readily interchangeable. Well the only way I can envision, but as they say you learn somnething new everyday.

Hey, if we're having a 2x4 relay, I could have that sweet sungun in the back of my van in under three minutes. But that doesn't mean it was intended to be removed with a skilsaw. :D

You could be right. If I have occasion (doubtful) I will try to get a picture. To be honest, I was staring at the cords more than the plumbing. I guess there's a different bar of permanence to every appliance. ;)

Re: Igniter for Instant HW heater

If it comes with a factory cord cap connection then whats the beef????The manufacturer has had the listing using the cord cap as means of connection.What does it matter what the plumbing end is unless you install that portion as well.
Look at a circulator pump it is installed by the plumber with no means of quick disc.It can be hard wired or cord connected,I cord connect since you need a jewlers screwdriver to get at the block connections.
That is by choice but if an igniter for an insta hot is cord installed then to alter would be a ul violation.If the circulator pump came with a cord cap then a recep is required.Same for an insta hot, cord from factory supply a receptacle.We are electricians not plumbers.Many of the new disposals come with an appliance cord connected from the factory.Are we allowed to hard wire it instead or install a receptacle???
Since we cord connect d/w and disposals its no big deal.But to change to a hard wired install is a violation right :D

Because the NEC is stating that there is more to it than, "It came with a cord."

Can you provide a reference to support that statement?

It remains to be seen if replacing a cord with a NEC-recognized wiring method would violate a listing.

Are we allowed to hard wire it instead or install a receptacle???

Is it prohibited?
 
Re: Igniter for Instant HW heater

You can not violate a UL listing.
You can mis-apply a listed product.
A UL Listing is simply a tool for an AHJ to employ, that says a product met certain requirements when it "left the factory" (except for a few locations in the NEC that specifically require a listing). The AHJ can choose to accept or reject any field modification.

There is nothing in 422 that requires a "quick disconnect". I believe the term is more like "ready removal". Shut off valves would allow the water heater to be removed without affecting the rest of the plumbing system, why wouldn't that be suffcient?

Re: Igniter for Instant HW heater

Jim, I can readily remove a hardwired, direct-connected appliance. So what does cord-and-plug connection accomplish?
