Add "A" to model number when ordering ASME. Optional on 120 - 250 models. Standard on 300 - 500 models. Maximum gas supply pressure for 120 - 250: 10.5" w.c. natural gas 14" w.c propane. Maximum gas supply pressure for 300-500 10" w.c. natural gas 13" w.c. propane. Manifold pressure: 4" w.c. natural gas 10" w.c. propane. Electrical requirements: 120 VAC, Blower 2.2 Amps FL, Igniter 4.0 Amps. SUGGESTED SPECIFICATION (Natural or Propane) gas water heater(s) shall be A. O. Smith Cyclone Xi model # _________ or equal, with up to 96% thermal efficiency, a storage capacity of ______ gallons, an input rating of __________ BTUs per hour, a recovery rating of ___________ gallons per hour (gph) at 100° F rise and a maximum hydrostatic working pressure of 160 PSI. Water heater(s) shall: 1. Have seamless glass-lined steel tank construction, with glass lining applied to all water-side surfaces after the tank has been assembled and welded; 2. Have a spiral-shaped heat exchanger placed entirely inside the tank, which shall be glass-lined to protect against acidic flue gas condensate; 3. Have foam insulation and an ASME-rated temperature and pressure relief valve; 4. Have a down-fired power burner designed for precise mixing of air and gas for optimum efficiency, requiring no special calibration on start-up; 5. Be approved for 0. clearance to combustibles. Heater shall be supplied with maintenance-free powered anode. The control shall be an integrated solid-state temperature and ignition control device with integral diagnostics, graphic user interface, fault history display, and shall have digital temperature readout. The water heater(s) shall: 1. Be design-certified by UL (Underwriters Laboratories), according to ANSZ21.10 standards governing storage-type water heaters; 2. Meet ASHRAE/IESNA 90.1-1999; 3. Be design-certified by Underwriters Laboratories for 180° F (62° C) water; 4. Meet SCAQMD Rule 1146.2 for low-NOx emissions. For conventional-vent specification: The BTH-120 - 250 water heater(s) shall be suitable for venting in 3. PVC pipe for a total equivalent distance of 50 ft and 4. PVC pipe for a total equivalent distance of 120 ft. The BTH-300 - 500 water heater(s) shall be suitable for venting only in 4. PVC pipe, for a total equivalent distance of 70 ft. For sealed-combustion direct-vent specification: The BTH-120 - 250 water heater(s) shall be suitable for venting with (3. or 4.) _______ diameter PVC pipe for a total equivalent distance of (50 ft or 120 ft) ________ feet. [Alternative venting: the heater(s) shall be suitable for sealed combustion direct venting using a (3. or 4.) ________ diameter PVC exhaust pipe for a total distance of (50 ft or 120 ft) ________ equivalent feet of vent and (50 ft or 120 ft) _______ equivalent feet of intake.] The BTH-300 - 500 water heater(s) shall be suitable for sealed combustion direct-vent using only 4. diameter PVC pipe and 4. diameter PVC exhaust pipe for a total equivalent distance of 70 ft. Operation of the water heater(s) in a closed system where thermal expansion has not been compensated for (with a properly sized thermal expansion tank) will void the warranty.
