Hearth size

[DavidApp]

Hello JRPizza

I have a 36" oven.
My stand is 59" wide and 63" from front to back. It is a bit tight, mainly front to back.

My inner arch is 19" by 12" and my vent is 21" by 13 1/2" and outside the vent columns is 37"

It has worked out well for me but I could have had more area outside the front of the oven.

I cleaned up the layout a little and corrected the vent width to provide door stop. Comments appreciated. I am framing my hearth and want to get my landing sized right.

Any comments on these dimensions would be appreciated. The layout is for a vent for a 36" oven. I think I have the inner arch dimensions correct - 19 inch opening and 4.5 thick. I show the inner arch width at the base @ 28" assuming these are half bricks sitting on edge. Is this correct? The vent area is shown at a similar 28 wide at base, but I didn't correctly space the opening to provide a lip for the door to stop against - is one inch about right for this dimension? If yes I would open the vent outer dimension to 30". I am showing the depth of the vent to be 1.5 bricks long (~13.5) with 3 inches deep for decorative arch. I'll update the sketch with the enlarged vent opening and any other suggestions I get and repost.

Thanks - John

You might want to make the front of the stand a little wider. I think I was at 32.5" and that was barely enough.

70"x70" will be good. I did that same size for my 40". I was feeling a little cramped when I did my vent. So make sure that you are very careful when you lay everything out as space runs out faster than you would think, but I made it all work just fine and could have moved back a little if I had thought about it.

Well, I went ahead and poured the cores in my 70X70 stand, so the question on stand size is moot!

Totally stuck on hearth size, and forum problems are keeping me from looking at some images that I think might help me. I have laid out a 70X70 corner base, but space is at a premium so would like to shorten to a 62.5X62.5. I have a sketch but am not sure about how much room the vent/landing need. I am showing 4.5 + 13 for vent/landing - will I have enough room to build a 36" igloo? Let me know what you think or if you need more information to help me out.
