How long to purge air in hot water line?

Last trip we had city water connection. No problems. Set up last night at a dry site.

Turned the pump on and then the sink hot water faucet to purge any air and make sure the water heater had water in it. Kept spitting air. The cold finally ran fine, but the hot line kept spitting. I was in a hurry, but let it run for at least 2 minutes.

Fresh water tank is at least 1/2, batteries at full charge.

Use the pressure relief valve on the tank to purge the air.

Update

UPDATE: I had parked on a pretty steep incline. I left the nose of the trailer pitched down off-level a few degrees, as it was getting too high in the for my comfort zone. I think this caused the water level gauge to read high, and put the water draw tube in a position to suck air. It worked okay when I got it home. I will continue to monitor.

Fyi don't ever use your taps to purge air for the hot water side!
ALWAYS use the pressure relief valve outside at the water heater.
Trust me it'll save you grief if you "forget" to open the bypass valves!
