VERTEXTM 90% THERMAL EFFICIENCY
CONTINUOUS HOT WATER
VERSATILE POWER VENT DESIGN
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 more hot water
than a standard 75-gallon atmospheric gas water heater. In fact, the fully
condensing Vertex design is so advanced, it can deliver “continuous hot water
for shower after shower”...a constant 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
■
Spiral heat exchanger keeps hot combustion gases in the tank longer to
lengthen the heat transfer cycle
■
Positioned in the center of the tank for more even heat distribution
■
Operates at 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 runs terminating through an outside wall.
Installations require ULC s636 approved PVC or CPVC pipe for venting.
- 2” pipe, vents up to 45 equivalent feet
- 3” 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 (VAA) 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-VENTTM** 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
