What you are doing is dangerous. If your ventilation isn't working correctly you could die from Carbon Monoxide. You should never grill inside.

Lol, it is a fancy natural gas range with a hood in my kitchen. I cook on it every day. Like these but different.

ok I thought you were grilling with an outdoor BBQ indoors. Those are designed to use indoors. As long as you have good ventilation and a carbon monoxide detector you should be ok.
