AAA Commercial Gas Boiler

Specifications

* For Propane models, derate Input and Ouput by 10%
* In Canada: For altitudes above 2,000 feet, contact the factory for the appropriate Input derate.
* In U.S.A.: For altitudes above 2,000 feet, reduce input 4% for each 1000 feet above sea level.
** Add 3” to dimension ‘A’ (1 1/2” to each side of boiler) to allow for 3” NPT water connections.
*** AAA2495 and above use two draft hoods and Dimension “E” is measured from both left and right hand sides.
† AAA480 and AAA600 are supplied with DIM B = 16.5” but can be field modified to DIM B = 10.5”
†† Gas Connection “F” shows typical sizes only. Connections may vary depending on the gas valve used.
Options:
– Natural Gas models add suffix “N” – Propane models add suffix “P”
– High/Low fire add suffix “M” – Full Modulation add suffix “MOD”

Features

STAINLESS STEEL ATMOSPHERIC BURNERS – High grade, heat resistant stainless steel burners ensure years of trouble free service, exceptional performance and improved fuel efficiency with virtually no combustion noise.

DOUBLE PASS STEEL HEAT EXCHANGER – A unique double pass fin-tube heat exchanger offers increased heat transfer by incorporating spiral-welded fins. Steel headers and risers complete the double pass design and contribute to a sturdy, light weight heat exchanger that resists thermal shock. Large 2”OD ASME boiler tube waterways resist plugging and minimize pressure drop, reducing circulator capacity requirements. The heat exchanger requires no field assembly and has no gaskets or push nipples. No other heat exchanger offers such strength, rigidity, low cost, and efficiency.

SYSTEMS INTEGRATION – A 2-stage BC-1 controller is included with all boiler sizes. Optional direct digital control contacts and outdoor sensors are available.

RAPID RESPONSE – The AAA Series design ensures rapid response to calls for heat which is especially important when using indirect hot water heaters and tankless coils.

QUALITY CONSTRUCTION – AAA Series boilers are constructed to ASME section IV standards with a maximum working pressure of 160 psi (1100 kpa) and a maximum operating temperature of 240°F (115°C). Each is tested to 240 psi and certified by a third party inspector.

EASE OF INSTALLATION AND OPERATION – AAA boilers are the smart choice for swift, user friendly installation and easy, convenient maintenance. Direct digital control terminal contacts are available for integration into most modern building management systems. The AAA Series boiler’s modular design allows for easy dismantling and reassembly to transport through narrow doorways and passages.
