I m live Los Angeles
I have a year old Williamson gas boiler with indirect-fired hot water heater that's giving me problems. Boiler fires up fine and reaches the proper temp.[180] and shuts down. Does not start up again until temp. goes down to 135. Replaced aquastat and no change. Aquastat has a reset button, dial for high temp., but no setting for lower limit. Honeywell 6000-E
Any idea on how to raise the temperture of the lower limit?

I'm confused
a L6000 series aquastat is typically used a a circulator contol
If the control has a red reset button, sounds like a circulator aquastat or boiler safety with manual reset feature, either one not used as a boiler operating contol, especially if a new boiler.
Is the control inserted into boiler, on the indirect or on the piping?
What is the full model number (like L6006E1018)
FYI, if the lower setting is adjustable, it is usually done on a white knob in control which is done as a differential. Adjustable from 5-35. set at 20, it is setpoint (180) minus 20 = 160 F on (lower) contect
