Re: Yanmar Heat Exchanger/Exhaust Elbow
I had to remove part of the anti-siphon hose to get it off of the fitting. The first half of the anti-siphon hose is still there, as is the upper U of the loop. The return hose from that U to the plumbing right angle fitting was removed to be able to unscrew the fitting. These were the only pictures I took at the time, so it just shows the situation with the hose and the fitting removed. The inlet fitting, the hose and the U at the top do not seem to collect as much debris or are as restricted as the entry into the exhaust elbow. Local knowledge told me that this is where the blockage usually occurs. If this did not clear the problem, that would have been the next place to check.
thanks, hope I answered your question.
