Yes, he does know what he's talking about. You are the one who does not. What you are suggesting is illegal. It's illegal because it's dangerous. Calling it "temporary" doesn't change that. The NEC has the force of law in most of the US. Where it doesn't, it's because the local codes are usually MORE strict, not less. Violating or ignoring the NEC is stupid, and potentially lethal. As beac pointed out, if you set your house on fire because you did something illegal, even if it was just "temporary," your insurance company can refuse your claim.
where did I tell the guy to plug it into an extension cord permanently? show me. I said if your power goes out, you can use it on a generator. which you have no clue about because it sounds like you are a home inspector? right up there with bored housewife real estate agent. the job listings all over the country advertised with no experience necessary. you don't know shit about the requirements of the water heater.
it says right in the water heater owners manual DO NOT USE IT WITH A GFI. and codes very from town to town and state to state. page 13 buddy, https://www.hotwater.com/Resources/Literature/Instruction-Manuals/Residential-Gas/ProLine®-XE-Power-Vent-40/50-Gal-Manual-(100271615)/ i'm not sure what connections you think you see in my picture. it's not there.
if it's a bad idea it would say so in the owners manual of the heater. here it is, have a look for yourself. also notice, it says no use of a GFI plug. https://www.hotwater.com/Resources/Literature/Instruction-Manuals/Residential-Gas/ProLine®-XE-Power-Vent-40/50-Gal-Manual-(100271615)/ it sure is amazing how much none of you actually know but pretend you're authority here lol.
are you butthurt I'm right? thought so. when you guys actually don't know what youre talking about. because none of you are in this field of work. you're the 3 stooges. I provided you with the manual. show me where I'm wrong...
Tell ya what, sunshine...you tell me what anything in this picture is, other than the torpedo heater and ladder, and I will bow down in awe to your incredible wisdom and experience...
lol it's just a bunch of electric boxes. let me take a picture of some random boxes and let you guess what they have inside. ok. youre a dipshit.
