Based on 80% Thermal Efficiency obtained in A. O. Smith engineering laboratories.

To compensate for effects of high altitude above 2,000 feet, recovery ratings should be reduced approximately 4%

for every 1,000 feet above sea level.

SUGGESTED SPECIFICATION

Water heater(s) shall be A. O. Smith Model __________________ or equal, with maximum storage capacity of 85 gallons, an

input rating of __________ BTU/Hr., a recovery rating of ___ GPH at 100º F temperature rise, and minimum thermal efficiency

of 80%. Heater(s) shall meet ASHRAE/IESNA 90.1-1999 requirements for thermal efficiency and standby loss, and meet

SCAQMD R1146.2 low-NOx requirements. In addition, heater(s) shall: 1) Include a powered gas burner, redundant main gas

valves, gas pressure regulator and flame inspection port. 2) Include a high-temperature limit control, dual-bulb thermostat for

accurate temperature control and anti-stacking compensation and a factory-installed AGA rated temperature and pressure

relief valve. 3) Be equipped with 1-1/2˝ NPT water inlet and outlet and a boiler-type handhole cleanout. 4) Shall be constructed

and stamped in accordance with ASME Boiler and Pressure Vessel Code and be so marked for a maximum working pressure

of 160 PSI. 5) Have a glass-lined steel tank with multiple anodes for corrosion protection, and polyurethane foam insulation.

6) Tank shall have a 3-year limited warranty against corrosion as outlined in the written warranty.

Venting: BTP heater(s) shall be supplied with a Barometric Draft Regulator for conventional atmospheric venting. BTPV heater(s) shall be supplied with an optional vent kit allowing for horizontal sidewall venting or direct venting.

Burner and Controls: Burner(s) shall be pre-mix design, with internal FGR and thermal cutoff, separate spark pilot ignition system, integral blocked flue sensor, glass view port, main gas regulator, automatic gas valve, manual test cock and manual gas shutoff. Burner(s) must be factory-installed, tested and started by an A. O. Smith Authorized BTP Start-up Agent before being placed into operation.
