Classic heat issue
I winterized our 2021 Classic 30 by using the blow out method. I followed the valve settings in the owner’s manual. We went out this past weekend for a short outing, as we missed our AS. Got no heat from the Alde system. Checked the valves and found that the number 1 valve was still closed. I opened it and heard what sounded like a rush of water. Still no heat. I’ll be going over today to check the fuse. I’ve read about an air bubble getting caught in these systems and needing to be bled down. Any ideas on troubleshooting this? I was using power as opposed to propane for the energy source.
