Sure glad I read this post because after seeing the photo in your "Cooking deck" post the other day I had decided it must not be a big deal to cook on a wooden deck. I found a cement fiber grilling mat at HD for about $45 but haven't bought it. After reading tee's turkey story I probably couldn't sleep at night if I had an all night smoke going. I've never had a smoker/grill so learning things like this post. Maybe you just saved me from burning down my composite deck.
I may be able to fit my Open Range on the back concrete porch when it gets here. The porch is covered and the wall of the house is brick.
How far from wall should I set the smoker? The ceiling of the porch is the standard 8' high. Would a smoker like the OR put out so much heat that it might set the ceiling on fire? These are kind of dumb questions but when it comes to smoking/grilling I ain't very bright.
I cook on 3 wooden decks , one at home & 2 at hunt camp..
The open range firebox is high , the most likely fire hazard would be from you dropping a lit charcoal briquette from your fire starter before your even cooking.
If you put down fire resistant mat don't put under the cooker but in front where you could drop a briquette.
The problem with under an porch is that smoke can find its way into the house, not dangerous unless you're spouse kills you.
If it were me I'd put pavers underneath & in front of firebox & not worry.
By the way I started this post to advise you.
