Potable water temperature is limited tobelow 210 °F and nominal water-containing capacityis below 120 gallons for all indirect-fired models.Accordingly, per Part HLW-101.2, Section IV of theASME Boiler and Pressure Vessel Code, all indirectfiredproducts listed are exempted from compliancewith the code.10
SECTION IIIGENERAL INFORMATIONFEATURESThis water heater contains the following features:HEAT EXCHANGER -- The heat exchanger (coil) has 3/4” NPTfemale fittings.Water heaters with a double-wall heat exchanger meet the UniformPlumbing Code for installation in all potable water systems. The doublewallconstruction provides protection in the event that either the potableor hydronic heat exchanger barrier is penetrated. The fluid will movealong in integrated leak path within the heat exchanger, leaving theexchanger through a weep hole located in the fittings. If a confirmedleak occurs, contact the plumbing professional who installed the waterheater or the manufacturer, listed on the rating plate, for additionalguidance.This indirect-fired water heater is appropriate for all potable heatingsystems, even where a single-wall exchanger is not approved by theauthority having jurisdiction.ADJUSTABLE THERMOSTAT – The temperature may be adjustedfrom approximately 80°F to approximately160°F. The thermostat isfactory set at 120°F. It is recommended that lower temperatures be usedto avoid the risk of scalding. Refer to the “Warnings” and the section onSCALDING in “Section VII – Operating Instructions.” It is furtherrecommended, in all cases, that the water temperature be set for thelowest temperature that satisfies your hot water needs. This will alsoprovide the most energy efficient operation of the water heater andminimizes scale formation.Setting the water heater temperature at 120°F will reduce the risk ofscalds. Some states require settings to specific lower temperatures.11
