To adjust the flame level you can adjust the internal regulator in the honeywell valve to limit maximum flame, unscrew the cover and back off the spring to lower the flame, then put the cover back on.
First off thanks for all the help in this thread. Great info that helped me get going really quick.
I currently have a single tier non automated setup and just completed testing of one of my HW values and ignition modules. I am running LP. This all worked great once I realized I have one Auber with a bad relay.
As a separate test to check flame size I ran one burner through the HW valve, ignition modlue and one straight through the LP gas line. As expected (I am sure I read something to this somewhere on HBT) the burner running through the HW valve was not as high as the one running straight from the LP tank.
Would tighting the regulator spring as you described above increase my flame size on LP? The difference was about an inch and a half. (clearly visible after sun down) I love the idea of the automation but hate to think I may spend more time getting up to temps.
FYI - Yes I did change all the orfices and spings for use with LP. I am running Hurricanes with the LP valve.
