The Alta Combi high efficiency condensing
boiler offers best in class, next-generation gas adaptive
technology that provides the shortest installation time and
lowest operating costs. The powerful gas-adaptive technology
offers true “no touch” combustion setup. There are no manual
throttle or offset adjustments. Engineered for five-minute
start-up, the boiler’s control system provides continuous,
automatic self-calibration of burner combustion by adapting
to component wear, variations in fuel, environment, and vent
air pressure to provide safe, efficient, and clean
combustion at all times.
Additional Alta Features
Converting from natural gas to LP is simple.
No additional parts or conversion kits are needed. The Alta
also includes a sensor-less reset, which performs the
functions of a conventional outdoor reset without the need
to install an outside sensor.
Domestic hot water response time is virtually instantaneous.
Domestic hot water temperatures are maintained under all
demand conditions, and the unit’s DHW recirculation system
can be set to either economy or comfort mode.
