Hello, Thank you for the question yes we do have a Natural gas conversion kit that would work with a 36" griddle, you can find this on Blackstone Products website.
No cover included. I bought the hard cover separate. It was well worth the cost to keep water off of the grill top.I have soft cover as well which doesn't keep water out.
I saw this item listed on the Blackstone web page, so I assume it's available, but have no idea when Home Depot might offer it.
We sent them originally much more than they forecasted so now we are all playing catch up. Mid to late July. Covid has caused a severe increase in sales.
Manufactured in the US and yes you can get the parts needed just look up model ! Parts come from UTAH.
Yes You need to have the converter kit for it but you should call the gas company to hook it up unless you have a license to do it yourself
