of Fort Worth, Texas. Supply quantities and model numbers as indicated on the plumbing schedule.  
Efficiency  
The water heater will operate at a minimum of 83% thermal efficiency. The water heater will comply with paragraph  
7.2.4.4, the thermal efficiency, the standby loss, and all other requirements of ASHRAE 90.1-1999.  
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 of the water heater will be National Board Registered for a working pressure of ____ 125 psi  
(standard) or ____ 150 psi and will be pressure tested at 1-1/2 times working pressure. The heating section of the water  
heater will be National Board Registered for a working pressure of 150 psi and will be pressure tested at 1-1/2 times  
working pressure.  
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. 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. The tank will be accessible in the field through a  
manway sized opening, allowing access to 100% of interior surfaces. All tank connection fittings will be nonferrous and  
removable from the tank.  
Tank Lining  
The entire lining will:  
be applied only after the tank is completely fabricated and all welding is completed.  
be a thermoplastic polymer that is NSF 61 approved and consist of FDA compliant materials.  
consist of multiple applications creating a continuous and nonporous barrier with no interruptions or  
discontinuities, particularly at the tank-to-fitting transitions.  
be confirmed after all welding is completed to be 100% void-free by the ASTM D-5162 wet electrode standard.  
have a dielectric resistance of 1600 volts per mil.  
The lined tank will not require anode rods and none will be used. Water heaters that use anode rods in a vessel that  
contains non-ferrous heating surfaces will not be acceptable.  
Burner and Venting  
Combustion will be provided by a forced-draft power burner with an oil train meeting the following agency  
requirement for the input specified:  
___ UL (standard)  
___ FM  
___ IRI  
___ Other ______________________  
Burner will be configured to accept ____ room air _____ direct inlet combustion air.
