I just hope that if I discover a solution to my ventilation cap, that is different from what I was advised here, the people who run this forum will let me add a final post to my locked thread. Such openness will make this site stronger, not weaker. I have done nothing reckless. I hired a licensed plumber who specializes in heating systems, and he tried to modify my ventilation cap. So far the only problem that has developed is the pilot being blown out when there are very strong winds outside. But even when this happens, my stove has a safety mechanism that quickly turns it off. I came to America because this is a country that is not scared of new ideas. People like Bill Gates, Steve Jobs and countless others became who they became because of asking questions and seeking new solutions. I'm sure when Gates dropped out of Harvard University and Jobs dropped out of Reed College there were people who wrote them off. Well, we all know who had the last laugh. But don't get me wrong. I do not pretend to be at the level of Gates or Jobs. Far from that. I just claim inspiration from them.
