Space between BGE walls and inside ceramic

Nothing official has been said here on the forum about the gap. However, there have been different designs & changes in the size of the fire box and fire ring of different models.

I would suspect the fit is not designed to be 'tight' as any air movement up between the fire ring/fire box and the egg wall will be an insulation and proved a much cooler feel on the outside of the egg.

If you only have 1/4" gap all the way around the fire box/ring I am thinking you have a good tight fit.

As an example on my medium if I slide the fire ring/box to the wall of the egg the opposite side has a full 2-1/2" gap. I was told by BGE that is not a problem in manufacturing or design. I was also told there was a new larger size fire ring/box being produced. I was offered the option to purchase the new larger size fire ring/box.

With that smaller size fire box/ring lighting my medium and getting that medium up to higher temperatures.

To solve the problem I ended up forming a filler rope out of aluminum foil in order to plug the gap.



I also came up with this resolve to get a much faster light and a much quicker climb in temperature on my medium egg.



After further use of the 'vent tunnel' I found the foil on the outside of the vent was not needed.

With the foil rope the start and climb to 500° dropped from 30 to 45 minutes (and never reaching that temperature) down to as low as 11 minutes.

With the vent and no rope the lighting and temperature to stable at 350° dropped from 20-25 minutes down to 11 minutes.

I am cooking at 5000' elevation.

These harder starting and longer time to temperature on the medium are not typical of my large, small or mini. The smaller size of the fire ring & fire box seems to be a problem at my altitude.

I'd assume it's a good thing for improved airflow, but I'm a noob...
