1 Technical Data Sheet AM Series Boilers The Advanced Modular (AM) Series represents the latest in high efficien - cy, condensing boiler hydronic technology. The AM series of boilers have - a unique modular design that provides exceptional reliability, service ability, and fuel savings from 399 to 1000 MBTU. Each unit is comprised of between two and four independent thermal modules firing up to 250 MBTU each at up to 5:1 individual turndown. This allows for superior tem - perature control and low-cycling operation. This unique design provides the multiple boiler redundancy required in a boiler plant, but with a single unit installation including a single set of water and gas connections and a single vent connection. When needed, multiple units are easily co-located and common vented to provide a boiler plant with the highest efficiency, turndown, and redundancy in the smallest footprint. Multiple units are sequenced via modbus through a Boiler Management System. High efficiencies and low vent temperatures mean the unit can be vented in PVC, cPVC, Polypropylene, and AL29-4C vent materials. The simple front-access design also means the unit is very simple to maintain and service. The AM Series may also be paired with a storage tank for water heating applications. High turndown means the AM requires a smaller storage tank than traditional water heaters. Features AM 399 through AM 1000 • High Efficiency Condensing Boiler Natural Gas or Propane • Boilers (AMB) Superior Turndown 8:1 to 20:1 depending on unit • Low NOx Emissions <20ppm • Direct or Conventional Vent with PVC, cPVC, Polypropylene, • or AL29-4C materials Concentric Vent Capability • • Common Vent Capability • Side wall common venting with no additional draft dampers • Small, Doorway-Size Footprint Superior Reliability • • Minimal Maintenance • Easy Front Access for Serviceability • Supports Integration to BAS System • Modbus Communication Standard

2 Thermal Efficiency Comprehensive tests were conducted to confirm the unit’s efficiency over its entire 50,000 to 1,000,000 BTU/ hr. operating range for a variety of operating conditions. These tests indicate that efficiency up to 99% can be achieved when the unit operates at its lowest firing rate (50,000 BTU/Hr input) with 80°F inlet water tempera - ture. Even at full fire (100% input), the AM Series delivers exceptional efficiency. Ratings AMB AHRI Efficiency Max Output Max Input Min Input Model BTU/hr Efficiency Range BTU/hr Number BTU/hr 93.8% 50,000 399,000 395,000 up to 99% AM 399 50,000 AM 500 495,000 500,000 93.8% up to 99% AM 750 50,000 750,000 742,500 up to 99% 93.8% AM 1000 93.8% up to 99% 990,000 1,000,000 50,000 *Note: max output varies depending on supply and return water temperatures. Please contact a factory representative for greater details. Unbeatable Reliability and Efficiency The Advanced Modular design uses multiple independent thermal modules for high reliability, high turndown, low cycling, and high efficiency. The on-board controller will automatically cycle lead-lag burners to balance run hours and cycles, as well as stage burners to provide multiple burners at the lowest fire rate. In a condensing - boiler low fire rates mean higher efficiency, thus the unit is always running at its most efficient. Integrat ed check valves and automatic shutoff valves on every module means that if a module is off, no heat is lost through either the flue or water side of that module. The innovative design features on each module add up to an industry-leading unit. For example, the AM 1000B boiler combines four independent 250 MBTU, 5:1 turndown boilers for a total input of 1000 MBTU, but a low fire input of one module at 50 MBTU. This means the unit as a whole has 20:1 turndown and can maintain incredibly tight temperature control with minimal temperature overshoot. - inde Emergency tech service visits are a thing of the past with the AM Series boiler. Each module has its own pendent burner, gas valve, ignition system, flame safeguard, check valve, and automatic water shut-off valve.

3 If one module were to ever go down, the remaining modules would be available to cover the load until sched - uled maintenance can be performed. The AM series boiler provides all of the advantages of a multiple boiler plant with all of the cost savings and simplicity of a single unit installation.
