Bob, all of my research points to adjusting the pressure. I have an email in to Dometic but searching other sites I’m not too hopeful. The manual calls for 11” wc and mine is 11.5”. RVEngineer says in a search lowering water column to 8” at high altitude is suggested. I bought a digital manometer and may try adjusting to get it to work. It would be nice to get a setting that works at all altitudes. As you mentioned, there isn’t a Dometic orifice for high altitude, only LP or Natural Gas.
