AM Series Boilers

The AM Series is essentially a pre-packaged boiler plant. 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 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.

Model Input Output*
AM 399 399,000 351,000-395,000
AM 500 500,000 440,000-495,000
AM 750 750,000 660,000-742,500
AM 1000 1,000,000 880,000-990,000

*Output depends on a range of factors including inlet temperature and ΔT. For further information contact your local factory representative.

Options and Accessories

Product Options

Double Block and Bleed Gas Train
Allows real-time cutover from natural gas to propane by rotating the fuel selector switch and changing of logic sticks.


Accessories

AERCO Condensate Neutralizer Kit 
Ideal for neutralizing condensate from condensing boilers and furnaces operating on natural gas or propane.

AERCO Control System (ACS) 
Optional multiple unit controller recommended for installations of eight or more boilers to maximize operating efficiency.

BelimoF6... HDU Series 2-way butterfly valves 
Designed to meet the needs of HVAC and commercial application requiring bubble tight shut-off for liquids. Typical applications include boiler isolation, chiller isolation, cooling tower isolation, change-over systems, air handler coil control, bypass and process control applications.

Communications Gateway 
Optional accessory supports boiler or BMS integration with BACnet, LonWorks and N2 systems.

Integration Panel 
Allows for automatic BST Master-function transfer to the next available unit in the event the original Master experiences a control panel or communication failure.

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

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.
