GPHE-50
Today’s homes demand more hot water than ever before, and the 90% efficient
Vertex power-vent gas water heater offers unprecedented levels of performance to
meet the need. The 50-gallon Vertex delivers hot water output that rivals a 75-gallon
atmospheric gas water heater. In fact, the fully condensing Vertex design is so
advanced, it can deliver “endless hot water for showers”…a continuous flow of over
3 gallons per minute.* Yet Vertex is easy to install, with height, diameter and
installation requirements similar to standard power-vent units.
HELICAL INTERNAL HEAT EXCHANGER
• Completely surrounded by water in tank, provides much greater heat transfer
surface than standard straight flue tube
• Helps produce 90% thermal efficiency, which saves money on operating costs
compared to a standard 78% efficient gas water heater
POWER VENTS USING PVC PIPE
• Combined vertical and horizontal vent runs terminating through an outside wall,
using Schedule 40 PVC pipe
• 2" pipe, vents up to 25 equivalent feet
• 3" pipe, vents up to 65 equivalent feet
• 4" pipe, vents up to 128 equivalent feet
MODULAR BLOWER
• Equipped with 120 volt, 60 Hz electrical system (rating 5 amps or less), 6-foot
cord with standard 3-prong connector
• 2" PVC pipe, elbows and condensate drain supplied to connect heat exchanger
outlet to blower
• PVC Vent Attenuation Assembly ( VA A) supplied
SIDE-MOUNTED HOT AND COLD RECIRCULATING TAPS
• Allows Vertex to be installed as part of combination space heating /water heating
applications or any system requiring a recirculating hot water loop, including
radiant floor heating
INTELLI-VENT
™
GAS CONTROL
• Equipped with nearly indestructible silicon nitride hot surface ignitor —
no standing pilot
• Advanced electronics for more precise control of water temperature and easy
to understand system diagnostics
COMMERCIAL GRADE GLASS LINING
• A. O. Smith PermaGlas

process provides superior protection
against
corrosion
• Protects all interior tank surfaces including inside and outside of helical
heat
exchanger
TWO HEAV Y-DUTY ANODE RODS
• Provide even more protection against corrosion
GREEN CHOICE
®
GAS BURNER
• Patented “eco-friendly” design reduces NOx emissions by up to 33%
and complies with Southern California and Texas requirements
FACTORY-INSTALLED TEMPERATURE AND PRESSURE RELIEF VALVE
MA XIMUM HYDROSTATIC WORKING PRESSURE : 150 PSI
* 3.07 GPM continuous flow, based on 65ºF inlet water temperature, 110º outlet temperature.
