Innovative Design
Fire tube heat exchanger with a higher
rated MAWP of 50 psi reduces unit pressure
drop. The easy access front panel can be
removed without tools to simplify service.
Easy Installation
and Serviceability
The LCD display is simple to navigate,
providing diagnostic and system
information in real words, not codes. The
first time you turn on the combi boiler,
you’ll be lead through our Set Up Wizard
for quick and easy programing.
Compact Size
The Preheat Function uses an integrated
recirculation pump to ensure that the
domestic hot water reaches its target
temperature faster. The Air Handler
Interlock prevents cool air delivery while
the boiler is in domestic hot water mode to
increase user comfort.
