Rinnai Tankless Water Heater - $950 (Mesa)

Have a brand new tankless water heater never installed by Rinnai.
Bought it in April of this year and cannot install because of wrong size gas lines in my home.
Would cost to much to have all my lines replaced with correct size, and Home depot will not take it back because it went past the 90 day return policy.
So here I am.
Its still in the box with all the parts it came with.
The only info I have of it is what's on the box (See pictures).
I do know you will need 3/4 inch gasline in your home to install.
If you have questions you can text me or google the item for info.
Only cash, no checks.
Scammers I will not verify any google confirmation number, don't waste mine or your time.
I will automatically block you! No Emails, I don't check them often.
