SPECIFICATION

(Natural or Propane) gas water heater(s) shall be A. O. Smith Cyclone LV model # _________ or equal, minimum 92% 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. Modulating gas burner that automatically adjusts the input based on demand. 2. Powered

anodes that are non sacriﬁcial and maintenance free. 3. Have seamless glass-lined steel tank construction, with glass lining applied to all water-side surfaces

after the tank has been assembled and welded; 4. Meets the thermal efﬁciency and/or standby loss requirements of the U. S. Department of Energy and current

edition of ASHRAE/IES 90.1; 5. Have foam insulation and a CSA Certiﬁed and ASME rated T&P relief valve; 6. Have a down-ﬁred power burner designed for

precise mixing of air and gas for optimum efﬁciency, requiring no special calibration on start-up; 7. Be approved for 0˝ clearance to combustibles.

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. No charge connectivety shall be provided allowing for remote viewing and fault notiﬁcaion via app. 1. All models are

design certiﬁed by Underwriters Laboratories (UL), Inc., according to ANSI Z21.10.3 - CSA 4.3 standards governing storage type water heaters; 2. Meet the

thermal efﬁciency and standby loss requirements of the U. S. Department of Energy and current edition ASHRAE/IES 90.1. Complies with SCAQMD Rule 1146.2

and other air quality management districts with similar requirements for low NOx emissions.

150K-250K BTU Input: For Standard Power Venting: Water heater(s) shall be suitable for power venting using a (3˝ or 4˝ ) _______ diameter PVC pipe for a total

distance of (50 ft or 120 ft.) ______ equivalent feet of vent piping. For Power Direct Venting: Water heater(s) shall be suitable for power direct venting using a

(3˝ or 4˝ ) _______ diameter PVC pipe for a total distance of (50 ft or 120 ft.) ______ equivalent feet of vent piping and (50 ft. or 120 ft.)______ equivalent

feet of intake air piping.

300K - 500K BTU Input: For Standard Power Venting: Water heater(s) shall be suitable for standard power venting using a (4˝ or 6˝ )______ diameter PVC pipe

for a total distance of (70 ft. or 120 ft.)_____ equivalent feet of vent piping. For Power Direct Venting: Water heater(s) shall be suitable for power direct venting

using a (4˝ or 6˝ ) _______ diameter PVC pipe for a total distance of (70 ft or 120 ft.) ______ equivalent feet of vent piping and (70 ft. or 120 ft.)______

equivalent feet of intake air piping.

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.
