SUGGESTED SPECIFICATION
Gas booster water heater(s) shall be A.O. Smith Master-Fit, Model Number ___________________, with a 32-gallon storage
capacity, an input rate of __________________ BTU/HR, _________________ gas, and a recovery rate of ________ gallons
per hour at a ________ degree Fahrenheit temperature rise, and a maximum hydrostatic working pressure of 160 psi.
Unit(s) shall have a fan-assisted combustion system, providing a power-induced draft of makeup air prior to burner ignition.
Unit(s) shall be equipped with intermittent electronic ignition with power on/off switch, which shall provide flame failure
response in less than one second. The burner for the unit(s) shall be easily removable. Unit(s) shall be equipped with a
factory-installed temperature and pressure relief valve, and a 2-3/4'' x 3-3/4'' tank inspection port.
The water heater tank shall be glasslined and protected against premature failure in the following ways:
1. Against electrolytic corrosion by multiple, factory-installed anode rods
2. Against failure due to overheating caused by the buildup of scale, film and other sediment by a self-cleaning device,
positioned inside the tank so that it directs the flow of inlet water in such a way that microscopic particles of precipitated
solids shall be kept in suspension and exhausted from the water heater on that or successive hot water draws.
Unit(s) shall meet or exceed ASHRAE/IESNA 90.1-1999, and be design certified by UL (Underwriters Laboratories), according
to ANSZ21.10.3-CSA4.3 standards governing storage-type water heaters.
