this is in a 2023 bigfoot truck camper, the Dometic water heater is a model WH-6GEA and 2022 year. It is gas and 110v.
bought unit at 7,000 feet
lit right away, burned what i thought was rougher than our 2000 model we traded in, and it went out after 30 seconds and relit automatically and stayed lit. Tried a couple times and it stayed lit, but to me was little rough burning, but flame was all blue
at 7,500 feet and above it lits, sputters for a few and then goes out, it shoots a small blue flame out the exhaust when it auto re lites. repeat and does not stay lit. i open the door and it stays lit, but is a bit rough but flame is blue.
At 500 feet elevation it lites, and stays lit, but a bit rough to me, flame is blue, and a few times it sputtered and shot the small blue flame out.
I do not want to rejet for hi altitude even though the majority of use is 7,000 to 10,000 feet. I do travle to sea level so need it to work there too is reason i do not want to mess with jetting. I think the big issue is the way the vent is designed. it is one vent top exhaust and bottom intake. it is too small of inlet and it is cut into the door at the top of water heater and burner tube where it needs air is at bottom of the door. Compared to our 2000 year model the intake vent area is about half. We have used it about 20 times and it is already turning the white metal cover a little brown just above the exhaust vent. I am thinking making a new temp cover and experimenting with adding a vent at bottom of heater near the burner tube. anyone have any ideas?

so your kinda in a pickel, sounds like it is justted wrong to start with if it works fine with the door open. the highest I have been with my camper is 6200 feet and I didnt have to adjust the air intake from when I camped at 30 feet. I initialy set it up so there was a tinge of yellow on the flame tips then when I shut the door it gooes just pure blue, but I have the adjustable air shutter. you might need to go to a different jet size, and since the air is not adjustable if the jet isnt hard to change out you might want to have a couple, one for higher altitudes and one for lower.
