SUGGESTED SPECIFICATION
(Natural or Propane) gas water heater(s) shall be A. O. Smith Cyclone Mxi model # _________ or equal, minimum 95% 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/IESNA 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.
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/IESNA 90.1. Complies with SCAQMD Rule 1146.2 and other air quality management districts with similar requirements for low NOx emissions.
120K-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
(50 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.
Water heater should incorporate the iCOMM
™
system for remote monitoring, leak detection and fault alert.
