Serious Dutch Oven help (PLEASE)/Thank you all

I just don't remember cast iron being so hard to season.
I got up early, is't 59 degrees out so I opened all the doors and windows in the kitchen and living room.
I followed Deans instructions --- 350* till hot---oil----500* for an hour. So here is the catch, my daughter in law came out of her room after 20 min caughing and hacking. (demonstrative) The smoke was getting to the baby's room.
I need a different way to season this. I don't have a gas grill and shouldn't make a bon fire. (burn ban)
Can I just fill it with hot coals?
Please help. I really want to make some of the yummy stuff here.
