Vulcan Hustler oven...burner problems.

I need some help here. I have never had these problems before.

I have a Vulcan Hustler pizza oven. The pilot goes out for no apparent reason after it has been on for hours. Sometimes, it goes out every minute, others, every hour or two.

I took the bottom shield off and the pilot stays on- no problems. It’s when I place the shield back on that it starts up again.

I’m thinking it’s some sort of oxygen mix problem. Does anyone have any advice for me.

I have had these ovens in other shops but never had this problem. I have new stones, heat shields and burners in these ovens.

Any help would be appreciated.



Does anyone have any insight?
