Residential/Commercial Gas Condensing High Efficiency Tankless Water Heaters T-H3J-DV/OS PRESSURE LOSS T-H3-DV/OS T-H3S-DV/OS Specification Water heater(s) shall be Model as manufactured by Takagi Water Heaters, 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 3 or 4 Schedule 40 PVC, CPVC, or ABS vent pipe, or stainless steel Category IV vent pipe at a distance not to exceed 70 (equivalent) for 3 vent or 100 (equivalent) for 4 vent, terminating vertically or horizontally as prescribed. Intake air pipe may be of such material as ABS, PVC, galvanized B-Vent, corrugated aluminum or stainless steel, or Category IV stainless steel not to exceed 70 (equivalent) for 3 vent or 100 (equivalent) for 4 vent. The heater(s) shall be controlled by an onboard solid-state printed circuit board monitoring incoming and outgoing temperatures with factory installed thermistors, sensing and controlling flow rate to set point temperature, controlling both air and gas mixture inputs to maintain thermal combustion efficiency. The heater(s) shall also consist of inline fusing, a spark ignition and sensor system, aluminized stainless steel burners, an air-fuel ratio sensor, a hi-limit temperature switch, modulating and proportional gas valves, a freeze protection sensor with ceramic heating blocks, and an overheat cutoff fuse. The water heater(s) shall be CSA listed, exceed the energy efficiency requirements of ASHRAE 90.1b-1992, and shall comply with SCAQMD Rule 1146.2 Ultra-Low NOx Standards.
