Greetings and start up question

Hello to all. Very informative website. I just received my first pellet grill and I am looking for some setup advice. I have the Jim bowie from GMG.
I have to set up outside and was wondering if a cover would suffice or if I should build some sort of enclosure. I would like to grill all winter and if rain occurs during the cook should I have some sort of lean to above or build a cabinet. Dont want to block off air completely. Any sugg. Thanks. Can't wait. I'll let you know how first ribs turn out.

Hey guys thanks for the advice. I fired it up for first time and grilled hamburgers. Turned out yummy. I followed that up w 2 racks of baby back ribs. I set the temp at 225. One rack had famous Dave's rib rub and the other I just used garlic powder. I used the 321 method and they looked great but they might have been a little over cooked.. I actually preferred the onion powder seasoning one better. I topped w sweet baby rays which was good. I'll keep trying and continue to post. Thanks
