Does anyone know if the F15 Riello ever came with a hydraulic delay? I have a boiler thats been running for many years without a problem and is now having a problem with starting. The problem could definitely be non-related to the hyd. delay. I am just curious if this even belongs on the burner and why someone would put one on if it didnt come on it. Thank You
I have never heard of a hydraulic delay. I have seen the air shutter delay when opening, but that is because the jack wasn't getting pure oil. A mix of air and oil or foaming oil due to an oil restriction will delay the opening of the air gate. Here is a link to this burner's install manual. http://riellotechlit.webs.com/documents/F-15%20HYD.%20JACK.pdf
