escape of air trapped in the water heater.To perform a long term pressure test including thewater heater, ALL trapped air must first be removedfrom the water heater.A loss of pressure during such a test, with novisible water leakage, is an indication that thewater heater contained trapped air.WARNINGFailure to operate the unit with the properwater flow rate can lead to appliance failure.Always install water flow switch so that theunit stops operating if improper water flowis present.Safety relief valve discharge piping mustbe piped such that the potential of severeburns is eliminated. DO NOT pipe in anyarea where freezing could occur. DO NOTinstall any shut-off valves, plugs or caps.Consult Local Codes for proper dischargepiping arrangement.Do not operate water heater with flow ratesin excess of the maximum flow rates listedin Table 2. Water heater tube erosion andpitting will occur. Thermal Solutions StandardWarranty does not cover problemscaused by excessive water flow rates.If a high head system pump is installed,assure that the water heater relief valveand system piping are capable of operatingproperly at the combined pressure of thesystem fill pressure plus the pump statichead pressure.22
