DOCX《Typical Specification》

30 data points for safety and operating controls, i.e., Alarm Contacts, Runtime Contacts, Louver Proving Switch, two Flow Switches, Tank Thermostat, Remote Enable/Disable (Wall Thermostat/Zone Control), System Supply Sensor, Outdoor Sensor, Tank Sensor, Modbus Building Management System signal and Cascade control circuit. A high voltage terminal strip shall be provided for Supply voltage. Supply voltage shall be

120 volt /

60 hertz / single phase. The boiler may be factory trimmed for optional supply voltages. The high voltage terminal strip plus integral relays are provided for independent pump control of the System pump, the Boiler pump and the Domestic Hot Water pump. The System pump and boiler pump dry contacts shall be sized for up to 1.5 hp/120V,

3 hp/240V or

30 amp pumps. The BOILER shall be installed and vented with a (select one): (a) Direct Vent system with horizontal sidewall termination of both the exhaust vent and combustion air. The flue shall be Category IV approved Stainless Steel sealed vent material terminating at the sidewall with the manufacturer's specified vent termination. A separate pipe shall supply combustion air directly to the boiler from the outside. The air inlet pipe must be sealed and may be other materials listed in the Installation manual. The boiler's total combined air intake length shall not exceed

100 equivalent feet. The boiler's total combined exhaust venting length shall not exceed

100 equivalent feet. The air inlet must terminate on the same sidewall as the exhaust. (b) Direct Vent system with vertical roof top termination of both the exhaust vent and combustion air. The flue shall be Category IV approved Stainless Steel sealed vent material terminating at the rooftop with the manufacturer's specified vent termination. A separate pipe shall supply combustion air directly to the boiler from the outside. The air inlet pipe must be sealed and may be other materials listed in the Installation manual. The boiler's total combined air intake length shall not exceed

100 equivalent feet. The boiler's total combined exhaust venting length shall not exceed

100 equivalent feet. The air inlet must terminate on the rooftop with the exhaust. (c) Vent system with Vertical rooftop or Horizontal sidewall exhaust with the combustion air intake in different pressure zones. The flue shall be Category IV approved Stainless Steel sealed vent material terminating at the rooftop or sidewall with the manufacturer's specified vent termination. A separate pipe shall supply combustion air directly to the boiler from the outside in a different pressure zone from that of the exhaust vent. The air inlet pipe must be sealed and may be other materials listed in the Installation manual. The boiler's total combined air intake length shall not exceed

100 equivalent feet. The boiler's total combined exhaust venting length shall not exceed

100 equivalent feet. (d) Vertical rooftop or Horizontal sidewall exhaust with the combustion air drawn from the equipment room. The flue shall be Category IV approved Stainless Steel sealed vent material. The boiler's total exhaust venting length shall not exceed

100 equivalent feet. Combustion air draw from the equipment room shall be supplied with properly sized combustion and ventilation air openings based on NFPA requirements. The BOILER shall have an independent laboratory rating for Oxides of Nitrogen (NOx) to meet the requirements of South Coast Air Quality Management District in Southern California and the requirements of Texas Commission on Environmental Quality. The manufacturer shall verify proper operation of the burner, all controls and the heat exchanger by connection to water and venting for a factory fire test prior to shipping. The BOILER shall operate at altitudes up to 4,500 feet above sea level without additional parts or adjustments. The BOILER shall be suitable for use with polypropylene glycol, up to 50% concentration without contingencies. STANDARD CONSTRUCTION The BOILER shall be constructed in accordance with the following code requirements as standard equipment. California Code CSD1 / Factory Mutual / GE Gap Massachusetts Code OPTIONAL CONSTRUCTION CODES The BOILER shall be constructed in accordance with requirements. (Option Code Below) KY Kentucky Code Note: Due to the large disparity in CSD-1 interpretation from state to state, please confirm to the factory all controls required in your jurisdiction. 1-11 C Printed in U.S.A.
