MENTS Ratings specified by manufacturers for most appliances apply for elevations up to 2000 feet For elevations above 2000 feet ratings must be reduced at the rate of 4 for each 1000 feet above sea level For example if a heater is rated at 120 000 Btuh at sea level to rate the heater at 4000 feet you subtract 4 once for each thousand feet x 04 496 input reduction x 120 000 Btuh original rating from the original rating Therefore to calculate the input rating at 4 000 feet 4 x 04 x 120 000 719 200 Btuh 120 000 19 200 100 800 Btuh At 6000 feet the correct input rating should be 91 200 Btuh The input reduction is primarily achieved by reducing the size of the main burner orifices To do this the main burner orifices require replacement with orifices sized for the particular installation elevation Correct orifice sizing and parts may be obtained from State Water Heaters When ordering be sure to state the model number and the altitude of the location where the water heater is being installed Upon completion of derating of the heater adjustment to the gas pressure regulator may be required See CHECKING THE INPUT section in this manual for inlet and manifold pressure requirements Also due to the input rating reduction required at high altitudes the output rating of the appliance is also reduced and should be compensated for in the sizing of the equipment for application FEATURES SELF CLEANING HYDRO CANNON These
