Question about RTO Atwood Water Heater - 6 Gal LP
Water heater lights okay. at sea level flame does not enter flame tube but comes back past igniter etc. at higher altitudes the flame enters the flame tube and exits out the exhaust end but with so much pressure it extends 3 or 4 inches outside the end. tube is clean not blocked etc. any ideas?
What size is the orifice? Are you using LPG or CNG? What pressure is the regulator set to?

The thermocouple sensor may not be in the best position to sense that the pilot is lit.
Adjust the thermocouple mount or simply bend the thermocouple "wire" so that the pilot flame is touching the tip.

You need to have a manometer (pressure test) done on your system. If all that is new and clean, as stated, then you either have low pressure or a faulty/improper, gas control.How's the flames look on stove burners?

SOURCE: I just replaced my gas
There are a couple of things to check....
I am assuming that the gas is LP or Propane....
make sure that the gas valve is for the right gas and not natural gas...
Also, it is possible that the regulator that cuts the pressure from the tanks is bad and that maybe why the original gas valve failed....
If you have the correct gas valve installed, get a gauge and check the pressure of the gas right before the gas valve...it should be somewhere between 8 and 12 inches water column...
If the regulator is not working properly, check that the vent hole in the regulaor is not plugged by a mud wasp nets or something like that...

If you see a little short round (cut-out)diode-like piece inside a clear plastic sleeve that runs from wiring to thermostat terminal,(usually right under pressure relief valve) remove it from the thermostat terminal, as well as wiring from heater (take it right out of the circuit) and connect that wire directly to the spade connector where it was attached at thermostat, and now try it. They are a one shot cut-out, and if it went, no power gets to the system and by removing it, you will see if it's the problem or not. They are a safety device that if for some reason you get too large of a flame from water heater, and it feels the flame/heat, it blows and cuts off power. Should be replaced when you get a chance, but at least you'll know what the problem is. Let me know if that works please.

Your on right track. When this happens and small flame still there, pull wire(s) off at gas valve, or test for voltage from ECO to gas valve. No voltage, then there should be no gas. Change gas valve.

Testimonial: "Changed the gas valve, now heater works as it should, No fumes and no flame after shutoff."
