Construction at high altitude

[novusins]

Does any one know of any changes necessary to compensate for high altitude, I will be building a low dome at about 2800 meters altitude ( 9100 feet ) .
And Im concern if the thin air will affect the burning ability of the oven .
Should I change the .063 ration for the door.
Or feed air to the oven.

thank you

I've seen forest fires burn at that elevation - fire is pretty adaptable.

For high altitude ovens I would follow the basic design, including the 63% ratio. About the only thing I would consider modifying is extending the vent/chimney higher as is done for wood stoves at higher altitudes.
