tips

Yes you can. Find a cast iron box and use that. If you don't have one wrap in foil and poke small holes in the foil. Place this on the burners and wait for it to produce smoke. Do not soak your chips in water. This just makes steam until the chips ignite.

Not sure what kind of grill you have. This would work great for a Weber.

welcome .... I have heard of people putting wood chips in aluminum foil and poking a few holes in it for use on a gas grill but I have never tried so not sure of the out come

I smoked on my gasser for years before getting a charcoal smoker. Used three packets of foiled chips on the front burner. Poked various amounts of holes in them to "stage" the smoke so it lasted longer. Place the foil packs on the burner under the grate. Turn the front burner on and leave the back ones off. Should be able to run at 250 no prob and have a decent smoke ring. Good luck!
