EXPLANATION OF RATINGS BOILERS RATING CSA INPUT Firing rate in BTU/hr. for atmospheric gas boilers based on CSA certifi cation test procedures. AHRI Input Firing rate in gallons per hour of oil or BTU/hr. of gas in accordance with Hydronics Institute test procedures. DOE Heating Capacity Heat output of the boiler based on standard test procedures prescribed by the United States Department of Energy. Applies to boilers under 300,000 BTU/hr. input. CSA Gross Output Heat output of the boiler based on tests conducted at the CSA Laboratory. Applies to atmospheric gas boilers with inputs of 300,000 BTU/hr. and over. AHRI Gross Output Heat output of the boiler based on tests conducted in accordance with Hydronics Institute procedures. Applies to oil, gas and gas-oil boilers with power burners when input is 300,000 BTU/hr. and over. NET AHRI Ratings The DOE heating capacity, CSA gross output, or AHRI gross output less deductions for piping and pickup. The amount of the deduction is determined by the AHRI Testing and Rating Code for Heating Boilers. Certified Ratings Ratings when boiler is fi red with special burners and/or under fi ring conditions other than stipulated by the AHRI code. SELECTING THE BOILER Boilers should be selected based on the Net AHRI rating when piping and pickup factors are considered normal. Net AHRI ratings are shown in BTU/hr. for water and steam and in square feet of steam. To select residential boilers for gravity hot water systems, fl oor panel systems, hot water or steam systems with larger than normal piping and pickup factors, and replacement boilers on hot water or steam systems with old style radiation and large piping, see chart below for piping pickup factors. ASME CONSTRUCTION All Advanced Thermal Hydronics boilers meet the requirements of the ASME boiler and pressure Vessel Code, Section IV, Heating Boilers. The Net AHRI Steam Ratings shown are based on a piping and pickup allowance as follows: Net AHRI Piping Net AHRI Piping Steam Rating and Steam Rating and 1000 BTU Pickup Factor 1000 BTU Pickup Factor 22.5 thru 940.7 1.333 1143.5 thru 1151.1 1.310 942.9 thru 950.4 1.332 1153.6 thru 1162.7 1.309 952.7 thru 960.2 1.331 1165.1 thru 1174.3 1.308 962.4 thru 968.4 1.330 1176.7 thru 1185.9 1.307 970.7 thru 976.7 1.329 1188.4 thru 1196.0 1.306 978.9 thru 984.9 1.328 1198.5 thru 1207.7 1.305 987.2 thru 994.7 1.327 1210.1 thru 1219.3 1.304 997.0 thru 1003.0 1.326 1221.8 thru 1231.0 1.303 1005.3 thru 1011.3 1.325 1235.0 thru 1241.2 1.302 1013.6 thru 1021.1 1.324 1245.2 thru 1251.3 1.301 1023.4 thru 1029.5 1.323 1255.4 thru 1264.6 1.300 1031.6 thru 1037.8 1.322 1268.7 thru 1274.8 1.299 1040.1 thru 1047.7 1.321 1278.9 thru 1288.1 1.298 1050.0 thru 1056.1 1.320 1292.2 thru 1301.5 1.297 1058.4 thru 1064.4 1.319 1305.6 thru 1314.8 1.296 1066.8 thru 1074.4 1.318 1318.9 thru 1328.2 1.295 1076.7 thru 1082.8 1.317 1332.3 thru 1344.7 1.294 1085.1 thru 1092.7 1.316 1348.8 thru 1364.3 1.293 1095.1 thru 1102.7 1.315 1368.4 thru 1387.0 1.292 1105.0 thru 1111.1 1.314 1391.2 thru 1412.9 1.291 1113.5 thru 1121.1 1.313 1417.1 thru 1445.0 1.290 1123.5 thru 1131.1 1.312 1449.2 thru 1501.9 1.289 1133.5 thru 1141.1 1.311 1506.2 and over 1.288 The Net AHRI Water Ratings shown are based on an allowance of 1.15 for piping and pickup.

A HeatNet Master-Member system (network) can contain up to 16 boilers. The HeatNet N2 Bridge is normally attached to the master and can provide most data points that the master periodically reads from each member. Per the N2 specification; baud=9600, data bits=8, stop bits=1, and parity=none. The N2 protocol is limited to 255 data points of each type. For this reason, the HeatNet N2 Bridge is configured to act like 16 different N2 devices. Each device represents a different boiler. The Master/Standalone boiler must always be enabled, but in order to conserve N2 addresses members must be specifically enabled.

KN Series Water Boiler Limited Warranty One-Year Warranty The Manufacturer warrants to the original owner at the original installation site that the KN-Series modulating water boiler ( Product ) will be free from defects in material and workmanship for one (1) year from the date of installation or eighteen (18) months from the date of shipment from the factory whichever comes fi rst. If upon examination by the manufacturer the product is shown to have a defect in material or workmanship during the warranty period, the manufacturer will repair or replace, at its option that part of the product, which is shown to be defective. Ten-Year Warranty The manufacturer further warrants to the original owner at the original installation site that the products Heat Exchanger (Cast Iron Block) will be free from defects from condensate corrosion and in material and workmanship for a period of ten (10) years (non prorated) from the date of shipment from the factory. If upon examination by the manufacturer the product is shown to have a defect in material or workmanship during the warranty period, the manufacturer will repair or replace, at its option the Heat Exchanger of the product, which is shown to be defective. Twenty-One Year Thermal Shock Warranty The manufacturer further warrants to the original owner at the original installation site that the products (Cast Iron Sections) will be warranted for twenty-one (21) years against thermal shock when the boiler is installed as a closed loop hot water boiler. This warranty will cover damage due to thermal shock, such as leaks to the cast iron sections from cracks from thermal shock. This warranty does not cover damage due to corrosion, scaling, sooting or to improper installation or operation the inlet and outlet water temperature differential across the boiler cannot exceed 100 degrees F. Water quality is important. As per ASME recommendations, dissolved solids must be less than 200 ppm. Also, ph levels must be in the 6.5-11 range. Failure to follow these guidelines will void the warranty.
