PVI Industries Water Heater PV 6813 User Manual

SPECIFICATION FOR DOMESTIC WATER HEATERS  
Condensing Gas Water Heater with Stainless Steel Tank  
Furnish and install a PLATINUM® SANI-STEEL® condensing firetube gas water heater(s) as manufactured by PVI  
Industries, LLC of Fort Worth, Texas. Supply quantities and model numbers as indicated on the plumbing schedule.  
Gas and Electrical Consumption  
The water heater will operate at up to 95% thermal efficiency when heating water from 40°F to 140°F. In sanitizing  
water temperature applications, the water heater will operate with a thermal efficiency of 93%. The water heater will  
comply with the thermal efficiency, standby loss, and all other requirements of ASHRAE 90.1-2001. Standby electrical  
consumption of the appliance will be 0.03 amps. Continuous amps during a firing cycle will be 1.3 amps.  
Pressure Vessel and Heating Surfaces  
The water heater will be constructed and stamped in accordance with Section IV, Part HLW of the ASME code.  
The storage section and heat exchanger of the water heater will both be National Board Registered for a working  
pressure of 160 psi.  
The heat exchanger will be a firetube design with the combustion chamber and all heating surfaces completely  
water-backed. The fireside of the combustion chamber will be of boiler-grade steel. The waterside of the combustion  
chamber will be non-ferrous and sealed with PTFE polymer. The fire tubes will be solid copper. The heating surfaces will  
be removable by unbolting from the pressure vessel, allowing 100% access to waterside surfaces. Heat exchanger  
removal will provide a manway sized opening, allowing access to 100% of interior surfaces. All tank connection fittings  
will be nonferrous and removable from the tank.  
The tank will be constructed of a stainless steel grade approved by the ASME code, part HLW for use with potable  
waters. The tank will utilize no lining. No sacrificial anodes or electronic anodes will be required or used.  
Burner and Venting  
Combustion will be provided by a pre-mix, fan-assisted, ported stainless steel burner. The gas train will meet the  
requirements of UL, FM and IRI.  
Water heater will be a category IV, condensing, positive pressure appliance. Water heater will vent through either  
PVC or CPVC as dictated by the stored water temperature (sanitizing temperatures will require CPVC vent). Water  
heater will vent through-the-wall unassisted for 100 equivalent feet through four-inch diameter pipe. Appliance will  
simultaneously be able to accept direct inlet combustion air through up to 100 equivalent feet of four-inch diameter  
material.
