Navien Error Code e012

I have a Navien CH240 Combi Boiler new in 2012. It is currently running on LP gas. I have over the years taken care of servicing it as far as cleaning filters and changing the flame rod assembly. I have even changed out the PCB board only to have the E012 error occur on a daily basis. I finally contacted a local service company who has been here 4 times and the error still comes on. Finally on the last visit they told me I needed a new air pressure sensor, gas pressure sensor and a new gas valve. I can get these items online and plan on doing it myself. My questions are- Will the new gas valve be set up for LP or will it need conversion? And will there need to be adjustments made to insure correct pressure to the boiler?

Hi, according to the manual 012 error is a dirty intake filter or a poor ground on the supply cord, donít just start replacing parts.
