July 2011R PG 3 OF 4 AOSDG25200 Commercial Gas Boilers SUGGESTED SPECIFICATION The hot water supply boiler(s) shall be an A. O. Smith Genesis® Model GW ___________________ having an input rating of __________________ BTU/hr. and capable of supplying no less than _________________GPH at a 100.F temperature rise when fired with Natural/Propane gas. The boiler shall bear the ASME “H” stamp and shall be National Board registered for 160 PSI working pressure. The boiler shall be test certified at 84%

O. Smith or an approved equal. Boiler(s) shall be gas-fired, and design certified by the Canadian Gas Association or an approved/accredited independent rating laboratory, capable of supplying_GPH (LPH) at 100°F (56°C) temperature rise equipped to burn_gas, with input rating of_BTUH(KW)/hr. and bearing the ASME code symbol. Boiler(s) shall be up flow type having all non-ferrous waterways, and employing a copper finned heat exchanger and a tightly wound copper coil combustion chamber with 160 p

Once initially setup the computer becomes optional. The key to the MPX-6 operating as a stand alone mixer is distributed intelligence™. In an IQ System the brains of the system live out in the system. This means the audio system is not going to be lost even if the computer or communication cables fail. The MPX-6 is an ideal choice for applications where computerized manual mixing or routing is desired and the automation of the SMX-6 or AMB-5 automatic mixers is not required. HARDWARE BLOCK DIAGR
