in THE MAIN WALL
I'm replacing a gravity water boiler that has a 3''main with a forced hot water boiler, can I tie into it with 11/4 coming off new boiler?

    Flow plates:

    If you are running gas as a cold start, why would you use them? Let 'er rip. And/or use ODR. If you're using an indirect water heater off the boiler, use an "I" series 4-way mixer. The house will heat like it was designed to do when the heat was installed.
