low pressure on surface burners

Hi Jerry. I was unable to find your model number either because it is incomplete or too old to find in the data base. I suspect that if your regulator is marked for both LP and Nat. gas that it can be changed. You will need to obtain the owners manual or conversion instructions to find out how to do this. Have you change the type of gas to the unit? There very well may be other things that need to be changed other than the gas regulator when converting the gas supply to then unit. If the gas supply has not been changed and your issue is low pressure to the surface burners, then converting the regulator is not going to fix the issue. The problem is going to be elsewhere. I hope this has been helpful.
