Specification
Water heater(s) shal be Model_________________ as manufactured by A. O. Smith Water Heaters, shal be a copper coil integral fin and tube construction with quick release brass or bronze waterways. Heater(s)
wil be factory assembled and tested.
The heater shall be vented with 3” or 4” ULC s636 approved PVC or CPVC or polypropylene vent pipe, or stainless steel Category III 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 PVC or CPVC, 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.
