Yesterday I completed my 1st 2 yr glycol change. I used the manual pump exchange & went thru at least 2 1/2 gallons (Rohmar). Only odd thing was I stopped both because I had put enough through and the glycol reserve tank started filling up. I figured the drain tube came loose & stopped draining thru the tubing.
I then ran the pump continuously on high for 15 min & later more until the reserve stayed at the max level. I get no errors and the heat turns but the trailer is not getting up to temp. Now sitting here next to the open Alde, flame and pump came ON but I heard some odd popping noises. I assume I still have air in the lines.
1st will air in the lines cause no to limited heat without an error displayed?
2nd apparently the auto purge won't burb all the air?
3rd and most important as it will get into the upper 30s tonight where are the manual purge valves located for the 2021 320 S.
I haven't had these issues before.

Prefer not to open the auto purge at the campground w/o doing it w/ cold glycol and lots of rags.
I'm pretty sure it's air I just don't know to burp it. This is the 1st time I've really had to play with the system. Good thing is checking the convector couplings I haven't seen any bulges....

You may know this already and not sure if it will help, but in this video, the bleeder valve is located behind the triangle cutout to the left of the speaker. About 2 min. into this video. I also have a '21S, but have never looked to see if it's actual there.

I was just at the NE Rally and Marvin from NuCamp gave a short talk on the Alde. He gave some troubleshooting tips, but in the end, he said to always try the reset button to get everything back to factory settings if nothing esle works...never know. Good luck.

Factory never returned calls and never found a manual bleed valve.
