SPECIFICATION FOR DOMESTIC WATER HEATERS
Condensing Gas Water Heater with Stainless Steel Tank
Furnish and install a PLATINUM®
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
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
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
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
