Ok to Switch Off New Yorker Boiler When Heating is Not Necessary?

I have been informed that maintaining a low limit <140 on a New Yorker Boiler is not recommended because it could lead to condensation and rust. Valid? Is it possible or preferable to switch off the unit completely for weeks at a time when heating is not necessary? The home has a separate hot water heater. Thanks!

    Correct. Much better to just turn it off outside the heating season.

    Just keep in mind if it at one time had a tankless coil in it ( they often did/do) that gasket likes to stay warm and could leak if cooled off.

    Thanks to all for you for the information. I apologize for my ignorance. This home and system was inherited and I know little about the system. I am told by the tech who serviced it that it does indeed have a tankless coil as the boiler was installed well prior to the external water heater being added. The New Yorker has two copper pipes entering a rectangular piece of metal bolted to the boiler casing with seemingly an adjustment knob of some type attached to the pipes. As such, should I not turn the boiler off for period of weeks? So it seems I cannot reduce the lower limit <140 and I cannot switch the boiler off leaving the system to draw tens of gallons of fuel over the summer months (and more during late spring and early fall months when the home is vacant and temperatures do not require the home to be heated). Thanks again. I appreciate the feedback and education.

    I keep tapping “agree” but will also add: “yes shut it off”

    I'd shut it off. I mentioned that it might leak only so you wouldn't be surprised. Don't panic if it does. You can address that issue later if it arises.

    Thanks again. How would such a gasket leak become evident to me? I appreciate this forum. Thank you.

    You would see water or corrosion stains appear dripping down from the rectangular piece of metal you mentioned earlier. There might already be some there! 😅
