Triangle tube Keystone...

Is this a Giannoni type HX, a bigger Fire tube version of the TT Prestige or something else. The literature is very vague on this... ty,kcopp

i am in the process of installing 3 750,000btu keystone boilers and yeah they are a giannoni, best i can figure is this is a boiler to temporarily fill the gap in the triangle tube lineup. i swear by triangle tube but to me this is no flagship boiler. i would not be surprised if it is replaced with something more impressive soon
