AM Series Boilers

The AM Series of commercial condensing boilers are essentially pre-packaged boiler plants giving you the reliability and redundancy of a multi-unit system in a single unit. Each unit consists of between two and four individual modules, each with its own combustion chamber, burner, gas valve, and combustion controls and safeguards, all tied together to common water connections and assembled in a single enclosure. This provides all of the advantages of a larger boiler plant, including high turndown and multiple-unit redundancy, while still keeping installation costs down and operation simple. Full front access means near-zero side clearance with no loss of serviceability when more than one million BTUs are necessary. Installations take up minimal space and remain simple to service. Standard Modbus controls easily connect to Energy Management or Building Automation System.

The high efficiency of the AM series condensing boilers and water heaters means less wasted heat and lower operating costs. In a condensing unit, lower fire rates return higher operating efficiencies. By running multiple modules at low fire rather than one large unit at higher fire, the AM series ensures the installation is always running at its most efficient. High efficiencies also mean lower flue temperatures and thus a range of venting options. All units can be vented in polypropylene, PVC, cPVC, or AL-294C vent materials. Available in 399, 500, 750 and 1000 MBH.

  • Low NOx and CO emissions
  • Turndown up to 20:1
  • Easy access and maintenance
  • Whisper quiet operation, even at full fire
  • Direct or conventional vent with PVC, CPVC, Polypropylene or AL29-4C Materials
  • Daisy-chain multiple units for applications over 1000 MBH

Options and Accessories

Installation Kits (application specific)

  • Gas Installation Kit – Gas Regulator, Pipe Union, Isolation Ball Valve, applicable coupling/bushing
  • Installation Kits (Boilers) – Pump Kit, Unions, Strainer, Isolation Valves, Hose Ball Valve, applicable coupling/bushing
  • Pump Kit – Pump, Circuit Setter, Mating Flange, RIB Relay/Starter
  • ASME Hydraulic Separator – 2.5” to 5” pipe size

AM Series Sequencing
AM Series Sequencing will maximize the performance of a bank of AM Series boilers or AM Series water heaters with single storage tank. The two sequencer options include:

  • AM Series Cascade Manager – Budget friendly sequencer with ability to control up to 8 units dedicated to either space heating or domestic water heating with single storage tank
  • AERCO Boiler Control 64128 – Advanced sequencer with ability to perform domestic hot water priority, equal run-time rotation, pump exercising and BACNet communication

Contractor Kit
Includes all the spare parts necessary to service and maintain the unit, including control board, igniters, flame rods, and all the screws, nuts and gaskets.

Sentinel Products
Compatible with all materials found in a hydronic loop, these chemicals offer overall protection of a heating system from sludge, scale, corrosion, and freeze conditions.

Secondary Low Water Cut-Off (LWCO)
Where required by building code, secondary LWCO must be installed external to boiler.
