Brush olive oil on chicken.Salt liberally. (I used probably at least 2 tbs for a 6 pound bird). Sprinkle with pepper. Cut celery and place in cavity of chicken.

Slice onion and lemon. Place in 9x13 foil pan. Add sage and rosemary. Fill with water.

Place the pan with lemon,onion and water directly on the grill racks. Place chicken directly on a cooking rack (I just used a cooling rack)over the pan of water. Put woodchips in another disposable pan and place directly on grill rack.

Close lid and turn grill on highest setting for 20 minutes.
