    Assembled and Test Fired

    Before a boiler is approved to leave our factory, when you select the Factory Package and Test Fire option, our expert team invests 4 - 5 days to fully assemble, wire, and test fire it. During test firing, key performance indicators are carefully monitored. If adjustments are made it will be test fired again to ensure it is running smoothly.

    Full assembly, test firing, and monitoring saves you time and money when your boiler arrives. Your team completes minimal assembly, hooks up your boiler, and it's ready to use. Optional: we will pipe to your accessories then disconnect for shipping to save even more time on arrival.
