Gas boiler problem

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?

It is what we call a cold start boiler. There is no low limit. The boiler does not run unless you get a call for heat or hot water. This is the most efficienct way to run the boiler.

You don't want to hear this, but annual maintenance is crucial to longevity of heating/cooling sytems. When was the last time this unit was serviced? Annual maintenance assures the unit operates safely and extends its longevity.

If you have a Williams, then go to Crown Boiler Bali Boiler - Williams Distributing Company

Manufacturer's for William's contact info is at Phone, Hours & Location - Williams Distributing Company

or Williams Mechanical

Sounds like normal operation to me ...

Heats the home OK, correct ?

It is a good idea to have the system serviced yearly ... so this one year old boiler should be looked at by a tech ... usually at the beginning of the heating season ...

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

Clancy, Thompson brings up a point ... which aquastat are you talking about ?

If it's got a red reset button, then it's an auxiliary high limit control ... does it look like this?


courtesy Honeywell, Inc.

If so, that's not an OPERATING control, it's a SAFETY control. It's an EXTRA high limit that should be set above the OPERATING high limit in the other aquastat.

It best to contact plumbing contractor
and ask to book an appointment for their service team, the best option and hopefully a quick repair.
