The new grates came yesterday afternoon, so I was not able to use them until today.
These are going to be a bit more of a learning curve than I anticipated.
I ran both burners and had a hood temp of about 400. I was almost done cooking the 4 burgers and had a huge grease fire. Pulled the burgers and killed the gas. Even with the hood closed it burned for a good 10 minutes. No damage and the burgers were fine. Best burgers I have ever made on that little gasser. I guess I can say the grates are "seasoned" now!
