Wanting a fire pit on legs...that's not a problem. I want to set it on the deck that is made of wood, problem. What can be used as a heat barrier underneath the pit that won't burn the wood? I've seen theese things burn green grass if you stoke them too much. Thanks
 
Back when we burnt wood in a wood burning stove in the house, there was a mortar board that looked like a white brick wall laid down.
We kept it under our stove. It was about 3/4 inch thick, strong enough to hold the stove and keep the heat off the carpet.
Problem was all the sparks and pops. They alway escaped and flew to where ever they wanted, and they didn't want to land on the board.
 
This pit will have legs and a mesh top to it. What do they call that stuff they put under a earth stove?
 
i was thinking to go with bricks under it or even some stainless steel on top of the bricks, so it reflects back.
 
It was just called "stove board" IIRC.
Probably could use the cement board used under ceramic tile too.
 
You have to have woodstoves on something if the floor underneath is wood here... Common thing is a 1/4" plate of glass. Don't know how/if that's hold up on a deck that could give/flex.... Maybe just a sheet of SS and be done with it.... I wouldn't fasten anything down just yet... Give SWMBO a chance to see it (the pit) after the first couple fires and rain and tell ya to get that nasty thing off her porch :roll:

I bought a neat one and it set on the porch almost a year with her talking about how nice it was and we oughta use it sometime.... 3 weeks after the first fire it was gone.....

Maybe just get you 4 (?) of them cement patio pavers or even a frame of tile edges and lay ceramic or terracotta tiles in there loose??
 
If its on the deck its too close to the house.You need an air space between the protective devise and the wood.A metal sheet againt a wood wall must be spaced out 1 inch.A metal sheet on a wood floor offers zero protection .To simplify this.Play a propane torch flame on sheet metal.You could put your hand 1 inch away from the metal and be ok.Put your hand on the metal, get burned.Flying embers can start fires.I was 20 feet from a burning brush pile.A wool shirt I had on had a 1 inch glowing spot on it.
 
Bricks offer no protection, you need an air space to stop heat transfer.Masonary chimneys require 2 inch clearance from wood.
 
The answers you are getting are a good example of why you should beware of information you see on a forum.
 
Wow.... almost as bad an idea as what we did several years back at halloween. Were taking the kids and their friends around to the neighbors trick or treating. Rural area, so we had them on a trailer with some straw. At the end we have a big party. It was chilly, so we took the trailer down the road to get the neighbor"s fire-pit-on-legs. It was burning, but no problem - we have wood stove gloves and set it on the trailer and went back to the party. A few of us riding back there managed to keep the flying embers from igniting too much... at least we had sense enough not to have the kids on there.

Bottom line, if you have a buddy thats a fireman - ask him. All it takes is a small glowing ember to get away and hide between the joints in some boards. You won't see it and several hours later you've got a problem. Have seen a plumber being very careful with metal shields and spray bottles when soldering near floor joists. 6 hours later..... here came the fire dept.
 
I dont have one on a deck,mines sitting on sand rock on the ground.but a friend here cut out a place in his deck,built up underneath with blocks ,covered that with slate on top for his pit to set on. The top slates overhand the deck maybe 2" or so to keep things from falling through, and the whole thing is (i would estimate) 2' or so larger than his pit on all sides. Of course his deck was pretty low to start with. There was one at a cabin I rented once that set off the side of the deck,all built of native rock and accessed with a couple of steps down.had seating of the same rock around it. looked really good but i never used it as we were fishing every day.other than that i cant help any.have you tried the manufacturer of your pit? they would probably have some ideas for you.or at least some clearances.
 
Huskers86, I am taking a guess here since you didn't provide a pic or description of your pit! The typical fire pit I hope your describing Is a LP tank End-Cap with 3 legs welded to it Style!. If that is the case build Leg Extensions! lift it up in the air about a 2 ft or so. Most Pits I have seen have 18 in stub legs already welded to them as they come from the Manufacture, Just find some pipe or square tubing that will slide over them, figure a nice height and cut 3 legs of appropriate length.
As Others have said there is No Substitute for Space / Air between the heat source and other flammable objects. I some folks that have a fire pit made out of a 6ft LP tank End Cap reject. They live near a End Cap Manufacture. Theirs sets out in their Patio area. And use it yr-round! Anyway Hope this helps.

NOTICE,in my answer to your question these are actual pits,not one of those things that stand on legs !I assumed when you said pit you are talking about a actual pit with sides all the way around.I use mine which is 18" deep to do most of the cooking at our cabin,but even with it i dont use it in high winds.I do have one of those things that are on legs someone gave me as a gift,but its been setting in the barn unused for 10 years.As far as i can see these are just a round charcoal grill with the legs cut off. A pit is a far different thing in my opinion.
 
DO NOT put it on a wood deck!!!!!as a firefighter for 42 years i have seen about 42 deck fires from this and most burn the house down late at night. just one little spark in dry deck wood and it's all over
 
Keep it away from the house... Even those enclosed 'chimeniea' things that are supposed to be safe have caused many fires because of sparks and hot embers.
Unless you're going to use an enclosed UL approved device installed to code then I'd suggest you keep it away from the house/deck entirely.
I'm guessing you want an open fire....

The risk of sparks and hot embers falling through the deck and causing a fire in the middle of the night would be my biggest concern... and it DOES happen.

Thanks for a the replies. I see a few important things that I'd not considered from responses. I'm thinking to scrap the idea of putting one on the deck because I really enjoy my house and don't want to burn it down! :wink: I've been using a 55 gallon barrel for a pit and I think it's best too keep open flames away from the house and buildings etc. Thanks again
 
For a long time we had one made out of a washing machine tub. I welded pipe legs on it and she liked to see the angled rows of holes all in flames all around the sides. We had it on top of "Wonderboard", a concrete 3'x5' floor under lay stuff from Home Depot. That on a wood deck but we had to for sure put it out when done, I too was a fireman a long time.
 
like this one.
