Selection GuideTo select the right A. O. Smith water heater for your home, you need to consider the size of your familyand other factors that contribute to your First Hour Rating Requirement. The chart below provides suggested

A. O. Smith Residential Water Heater selection guidelines for several family sizes.

To Choose the Right Water Heater for You…

1. Determine whether your family is Low Demand or High Demand. You should consider your family to be High Demand if...

• There are more than two full baths in the home.

• There are (or will be) teenagers living in the home. It’s a fact: teenagers use more hot water for showering and washing clothes.

• If you have an oversize whirlpool bath or other large tub. As a rule of thumb, the water heater tank capacity should be 100% of the bathtub capacity (example: 75-gallon tub/75-gallon water heater).

2. Find your Family Size and Demand Profile in the chart below, and read across to find the First Hour RatingRequirement for your family. If you decide your family is High Demand, consider moving up to the next FirstHour Rating level.

3. Consult the charts on the following pages for an A. O. Smith residential water heater with a First Hour Ratingthat meets your requirement.

Specialty-VentSpecialty-vent gas water heaters are an alternative to standard metal-vent water heaters.They provide venting flexibility in replacement applications and offer useful choices for location ofgas water heaters in new homes. Specialty-vent benefits include...

Flexible Installation – Horizontal-venting options allow tremendous flexibility for placement ofthe water heater in the home. For example, A. O. Smith Power Shot® power vent and SealedShot® power direct-vent can vent up to 40 feet, using inexpensive PVC, CPVC or ABS pipe.

Direct-venting for proper combustion – Insufficient indoor ventilation can deprive a gaswater heater of enough air for proper operation. Sealed Shot® power direct-vent and Sure Shot®

direct-vent water heaters have “two-pipe” systems that vent to and draw air from outside thehome, eliminating concerns about indoor ventilation.

Power-Vent• Performance that rivals a 75-gallon

gas water heater

• Delivers “endless hot water”

• Completely surrounded by water in tank, improves heattransfer surface over standard straight flue tube

• Helps produce 90% thermal efficiency, which saves moneyon operating costs compared to a standard 78% efficientgas water heater

• Versatile power-vent design allows combined vertical andhorizontal vent runs terminating through an outside wall,using Schedule 40 PVC pipe

• Modular blower equipped with 120V, 60Hz electrical system(rating 5 amps or less), 6-foot cord with standard 3-prongconnector

• Two heavy-duty commercial-grade anodes ensure protection against corrosion

• Intelli-Vent™ gas control for more precise water temperature control

• Side-mounted hot and cold recirculating taps

• Long-lasting pex cross-link polymer diffuser dip tube

• Six-year limited warranty on tank and parts

Specialty-VentSpecialty-vent gas water heaters are an alternative to standard metal-vent water heaters.They provide venting flexibility in replacement applications and offer useful choices for location ofgas water heaters in new homes. Specialty-vent benefits include...

Flexible Installation – Horizontal-venting options allow tremendous flexibility for placement ofthe water heater in the home. For example, A. O. Smith Power Shot® power vent and SealedShot® power direct-vent can vent up to 40 feet, using inexpensive PVC, CPVC or ABS pipe.

Direct-venting for proper combustion – Insufficient indoor ventilation can deprive a gaswater heater of enough air for proper operation. Sealed Shot® power direct-vent and Sure Shot®

direct-vent water heaters have “two-pipe” systems that vent to and draw air from outside thehome, eliminating concerns about indoor ventilation.

Power-Vent• Performance that rivals a 75-gallon

gas water heater

• Delivers “endless hot water”

• Completely surrounded by water in tank, improves heattransfer surface over standard straight flue tube

• Helps produce 90% thermal efficiency, which saves moneyon operating costs compared to a standard 78% efficientgas water heater

• Versatile power-vent design allows combined vertical andhorizontal vent runs terminating through an outside wall,using Schedule 40 PVC pipe

• Modular blower equipped with 120V, 60Hz electrical system(rating 5 amps or less), 6-foot cord with standard 3-prongconnector

• Two heavy-duty commercial-grade anodes ensure protection against corrosion

• Intelli-Vent™ gas control for more precise water temperature control

• Side-mounted hot and cold recirculating taps

• Long-lasting pex cross-link polymer diffuser dip tube

• Six-year limited warranty on tank and parts

* Height to top of blower outlet.** Distance from back of heater to front of gas valve.
