AM Series Variable Speed Boiler Installation Kit

To help you install your new AM Series boiler, AERCO has compiled everything you need into one, convenient place, our AM Installation Kits. These kits eliminate the need to separately purchase all near-equipment piping components as well as remove any guesswork regarding which size piping is appropriate for your project. You’ll have all the components you need at your fingertips to get your AM unit installed quickly and properly so it operates at designed efficiencies throughout all load changes.

Design Guides for Piping Selection 
Using our AM Series Primary Loop Design Guides, we’ll also help you select the correct piping for your specific application. To use these simple guides, you only need to know your equipment model and the design temperature rise, and we’ll tell you which installation kit and accurately sized piping you need. See examples below:
