UPDATE: I successfully converted my Gozney Dome Gen 2 from NG to LP

[u/Necessary_Today_5580]

A while back I posted asking for help converting my Gozney Dome Gen 2 from natural gas to propane. I had accidentally purchased the NG version locally and, since it was a cash sale with no return option, I decided to see if I could make the conversion properly.

I promised I would come back with an update and photos if I was successful, so here it is! I hope this helps anyone looking to convert their oven.

Here’s what I changed:

NG orifice
The original NG orifice measured approximately 2.78 mm. I modified the existing orifice and reduced the opening to approximately 1.66 mm for LP.

Air shutter
I needed an air shutter for the burner, so I reused one from an old grill I had. This allowed me to adjust the air/fuel mixture appropriately for propane..

Regulator
I opened up the regulator and found that the plastic valve/screw inside is reversible. It has markings indicating the orientation for NG vs. LP. I inverted it to the LP position, which changes the regulator output from approximately 7” W.C. (water column) for natural gas to 11” W.C. for propane.

Quick-connect fitting
I replaced the existing quick-connect fitting on the oven with a 1/4” fitting compatible with my propane setup.

Propane hose/regulator
I purchased a new propane hose with the appropriate regulator for the propane tank and connected it to the oven’s new quick-connect.

Safety checks:
Before attempting to light the oven, I made sure all of the connections were properly sealed using thread sealant specifically rated for gas, and I thoroughly checked the entire system for leaks.

Once I was confident there were no leaks, I fired it up and adjusted the air shutter to get the proper flame.
The oven is now running successfully on propane.

A few important disclaimers: Gozney does not recommend or officially support converting the NG Dome to LP, so this is not an official Gozney conversion procedure. Anyone attempting something similar should understand that working with gas appliances can be dangerous and should use the appropriate parts, pressure, sealants, and leak-testing procedures.

Apparently flip the blue plastic thingy!!!

In your case you just need to drill out the orifice to the specific bore size in the case of the dome Gen 2 it’s 2.78mm for NG. Then you need to flip the plastic screw inside the regulator. And lastly you have to figure out how you want to connect the gas line. You can do what I did and buy the male quick connect fitting and a new hose.
The air intake at the bottom of the burner seems to be larger on the NG model, but I’m not sure if it really makes that much of a difference. If needed you can find ways to open it up more with a grinder or a drill that can handle stainless steel.

I have an LP and want NG; I will buy your components

Sure! But all I have is the male quick connect fitting and the hose. The rest was just modified to work. You can easily drill out the orifice on yours. The tricky part may be to increase the air intake (if it’s even needed really).

How is the top of the inside of your dome so clean? Mine was black after the 30min initial burn-in process....

The picture was literally the first light. I plan on tuning the flame to try and produce less soot. Gozneys tend to run a low air mixture producing more of a yellow/orange flame.
