psig. Water heater shall require a minimum gas pressure of 3.5"
W.C. (Natural Gas) at 1,000 scfh (full load rated capacity).
MODE OF OPERATION
Heater shall include integral factory wired operating controls
to control all operation and energy input. Control of discharge
water temperature shall be set through an internal setpoint with
a fi eld adjustment of 100°F to 180°F. Heater shall be capable of
maintaining the outlet temperature within an accuracy of ±2°F*.
This shall be accomplished by modulation of fi ring rate from
100% to 11% of rated input. Unit shall operate with an Inverse
Effi ciency Curve, with maximum effi ciency achieved at minimum
fi ring input.
* based on static stability test
CONTROLS INTEROPERABILITY
The control board may be linked to other Bosch tankless water
heaters through the use of a cascading kit. This accessory shall
cause the unit to perform as described above while activating
or deactivating other units in the system. Additional Bosch
