^ Average water temperature = (entering water temp + leaving water temp) divided by 2.
** For type 5, at 5 PSIG, if (total MBH divided by 0.961) divided by coil tubes is more than to 50 LB per tube, the condensate loading may be too high. At
higher pressures the condensate loading can be more than 50 LB per tube. Get a computer rating for the application.
