Utica Boilers SSC Spezifikationenblatt

3.0" w.c. (0.7 kPa)

13.5" w.c. (3.3 kPa)

5.0" w.c. (1.2 kPa)

13.5" w.c. (3.4 kPa)

6.2.2  Combustion air blower shall be equipped with a variable speed blower to regulate the 

amount of premix gas/air through the blower assembly and into the burner.  The on board 

control system shall regulate the speed of the blower to modulate the capacity of the boiler 

from 20% input firing rate up to 100% input firing rate.

6.2.3  Gas Burner shall be constructed of a stainless steel mesh.  
6.2.4  Ignition system shall consist of a direct spark igniter (DSI) and separate flame sensing rod.   

Control System
7.1  Boiler Control System.  Boiler shall feature an integrated modulating control.  The control shall 

sense the supply water, return water and outside air temperatures and adjusts the firing rate to 

deliver the amount of heat needed to the structure.
Boiler Control System must consist of:

• Replaceable fuse /extra spare fuse shipped with the control.
• User interface with LCD screen display English text—boiler status indication .  
• Function Programming Keys  - Reset, Menu, Enter and arrow s  (+  - ).
• Central Heating CH and Domestic Hot Water DHW set points.  Domestic hot water priority 

with programmable maximum priority time .

• Outdoor air sensor.  Programmable reset curves and warm weather shutdown or fixed 

water temperature operation. 

• Boost function temperature setting and adjustable boost time.
• Maximum power function to restrict firing rate in heat mode but allow full power in DHW 

mode.

• Integral multiple boiler control capability up to 16 boilers.  Requires an optional system 

sensor 

• Service reminder status display on the user interface with programmable settings in a 

range of 1 to 999 days 

7.1.1  The control system shall continuously monitor the boiler during operation and standby 

modes. The control shall operate in such a manor to receive input data from the supply, 

return and outdoor air temperature sensors and adjust the modulation rate accordingly.    

7.1.2  The Boiler’s control system shall consist of the following safety devices factory installed 

on the boiler:  high limit temperature sensor, vent temperature sensor, heat exchanger 

temperature limit, UL Listed, probe type Low Water Cut Off (LWCO).

Primary Secondary Piping System
8.1  The boiler shall be equipped with an internal primary loop and pump.  
8.2  The internal primary loop piping system will contain a manually operated ball valve.  The valve 

shall be set by the factory in the full open position.
