Specification Water heater(s) shall be Model _________________ as manufactured by State Water Heaters. The water heater(s) shall be a copper coil integral fin and tube construction with quick release brass or bronze waterways. Heater(s) will be factory assembled and tested. The heater shall be vented with 5” Stainless steel Category III vent pipe a distance not to exceed 50’ (equivalent) feet terminating vertically or horizonatlly as prescribed. Intake air with optional direct vent kit may be of such material as PVC not to exceed a total of 50’ (equivalent). The heater(s) shall be controlled by on board solid state printed circuit board monitoring incoming and outgoing temperatures with factory-installed thermistors, sensing and controlling flow rate to set point temperature with control both air and gas mixture inputs to maintain thermal combustion efficiency. Unit also consists of ground fault interrupter, inline fusing, spark ignition and sensor system, aluminized stainless steel burners, air-fuel ratio rod, Hi limit switch, modulating and proportional gas valves, freeze protection sensor and heating block and overhead cutoff fuses.The water heater(s) shall be CSA listed, exceeds the energy efficiency requirements of ASHRAE 90.1b-1992 and complies with SCAQMD Rule 1146.2 and other Air Quality Management Districts with similar requirements for low NOx emissions.
