The boiler manufacturer said this would probably work, but the contractor hadn't mentioned the pipes.
Boilers are classified also by their pressure capacity, design type and use. Maximum allowable working pressure, or MAWP, is the highest amount of pressure that the vessel (boiler) is designed to withstand. This pressure is measured in terms of pounds per square inch or “psi,” and gauge pressure is expressed as “psig.”
