The regulator was set correctly. It was the individual burner orifices that were incorrect. Apparently there was basically a grab bag of options in the propane conversion kit like 10-15 for only 5 burners. The stove has colored paint marks in each burner and the card with the orifices had a few with matching colors. When it was converted prior to install, the crew apparently just matched color for color. But for whatever reason the instructions were clear on what size orifice was needed per burner and it did not match color for color. Most of the burners have noticeably higher flames than they did before. The tech also adjusted each valve for the proper flame height. That may have had as much effect on heat as the orifices?
