Byron - looking at your profile, you have a 2017 3820fk. I am not sure what stove you have but someone here will know.

I have learned this from reading the forum …the propane valve needs to be opened slowly to prevent an automatic shut off. My unit has the Furrion stove with spark lighters. I have never timed it but it seemed like it may take 10-15 seconds to light. I always let all three burners run for 30 seconds or so before I try the water heater. My unit has a Suburban IW60 on demand water heater. After I run the stove burners - I open the water and see if I get hot water.

Other folks here will have better advice for your particular unit. I don’t think our 2018 InCommand panel has anything to do with the water heater.
