Hello Skitz -
Great Question! When building a BrickWood Oven, you can use wood, coal, propane & natural gas. The wood and coal options are not brainers… super easy.
The Propane and Natural Gas options require a bit of pre-planning before you build your base (as you want to run a gas pipe through the base slab).
As for you concern about the clogging of the fuel burner due to wood soot and/or ash - don’t worry, here’s why:
-
You will have a 1/2 - 3/4" opening around the gas burner in the hearth (cooking area) and base. Wood and coal ash will fall through this opening before it touches your burner.
-
A local metal shop can create a small 3-sided / stainless steel shield that you can use to block the burner mechanism from the wood & coal. Very simple to build - 3 sides - each side is 3" in length with a 45 degree bend. On the bottom, there is a 1" flange to keep it upright. This will allow the burner to function and shield the burner from wood if you choose to burn both at the same time.
-
If the burner should ever get clogged, simply detach the burner and clean the burner nozzles w/ a toothpick or a wire shirt hanger.
I guess we should add - Make sure you turn the burner off BEFORE you attempt to clean the nozzle. Safety First!
Hope that answers your question!!
As a side note - we don’t manufacturer or resell gas burners, but if you want at great quality burner, please contact Mark Ward at -
