Just to be on the same page are you burning wood or coal
having a expansion tank helps,but at 260 degrees thats dangerous and is your PRV activating and what is the boiler pressure at 260 degrees
before adding another dump zone you need to learn to control the boiler first
have you looked into manually sliding the draft door,is it too tight and sticking,is the draft motor malfuncting
what size house are you heating and what/how many btu's do you need
is the boiler oversized for your needs
I have an over sized boiler,but will be needing all that extra capacity later when hooking up the shop.My boiler was over heating and activating the dump zones all the time before I learn how to control it.I needed to reduce the firebox by 50% then all the problems calmed down.
Can you show some pics. of your set up,
