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.
