Somewhere inside the coach, you should have panel that looks like the photo below.
Turn on the "Diesel". You should hear the Aqua-Hot start, then light.
The following lights should be illuminated on your electronic control board:
"Heating Status" - Thermostat calling for heat
"Diesel Burner Status" - Diesel switch in coach on
It will take around 15 minutes to heat up the coolant in the Aqua-Hot.
Manual for your Aqua-Hot here: https://www.aquahotparts.com/eSource...t/Manuals.aspx
You probably have a model AHE-450. Verify that by checking the data label on the outside of your Aqua-Hot.
