Garage Boilers 2 zone system

Hi new to the forum and looking for some help with a boiler system, that I am putting in to the garage for a existing 2 zone floor heating system. I purchased a Laars mini therm 50000 BTU boiler. I am looking for a basic designs or plan as to how to build this. The original system was hot water tank ,a circulating pump and 110 thermostat, but now I would like to upgrade and make it look professional. Any help with some blueprints for this would be appreciated.
