FASTEST INSTALLATION
Pro-driven features for the fastest, most customer-friendly installation
include:
Best Retrofit Option
Plumbing flexibility for quickMastertemp®and Max-E-Therm®replacement that
requires no plumbing adjustments.
Ultra-Compact
Lightweight Design
Easy to store, transport, and install, JXi ™ easily fits on a 2′ x 2′ pad and
is 38% lighter with a 28% smaller footprint.
*Compared to major competitor models
Flexible Installation
Top can be easily removed for increased accessibility and rotated 180 degrees so you never need to rotate headers. Also includes a flip-up electrical panel for convenient setup and service.
84% Thermal Efficiency applies to 260K and 400K BTU Models with Copper Heat
Exchangers, 200K BTU
and all models with Cupronickel heat exchangers are 83%, see back page for
complete model listing.
Versa Plumb® -Ready
Installation in the Versa Plumb system reduces plumbing costs and increases
energy efficiency, all using the smallest footprint available.
Sweep elbow included in all JXi models
**ASME Certified Models Now Available**
JXi™models are available with robust heat exchanger tubes and corrosion-
resistant bronze headers to meet the high stresses of commercial
installations.
Not available with VersaFlo Integrated Bypass technology
SAVE EVEN MORE WITH OPTIONAL
VERSAFLO ™INTEGRATED BYPASS
VersaFlo not available on ASME-certified models.
Here’s How:
» The heater is typically only used 3.5% of average annual pump runtime, the
other 96.5% of the time the heat exchanger can be bypassed.
» JXi with VersaFlo activates the built-in flow bypass valve based on call for
heat to avoid running water through the heat exchanger when water does not
need to be heated.
» When used with a variable-speed pump, JXi with VersaFlo requires
considerably less electricity, thereby providing for significantly reduced
electricity costs.
» VersaFlo Integrated Bypass is available on select models or can be easily
added to any JXi heater in the field.
Versus similar system without VersaFlo. See JXIVFKIT installation manual
for more details.
5-YEAR HEAT EXCHANGER WARRANTY
JXi heaters with VersaFlo factory installed receive an industry leading 5-Year
standard warranty
on the heat exchanger.
