Revised October 2012
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 the thermal efficiency and standby loss require-
ments of the U.S. Department of Energy and current edition of ASHRAE/IESNA 90.1, comply with SCAQMD Rule 1146.2 (BTPV 540 and 650 only) and other air quality
management districts with similar requirements for s. 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 e. 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 cut off, 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.
