APPLICATION:  

Modulating Gas fired water heating boiler for indoor installation. Approved for closet or alcove installations. 

For use with natural or liquefied petroleum (LP/Propane) fuel gases, LP conversion kits available as option. 

Wall mounted – optional floor stand available. All boilers are factory assembled with controls and wiring 

and test fired to ensure dependable performance. Boiler shall be certified for Category I and Category III 

applications.

Copper tube heat exchanger is manufactured and tested in accordance with American Society of Mechanical 

Engineers (ASME) and certified by Canadian Standards Association (CSA). Copper tube heat exchanger is 

tested for maximum allowable working pressure of 43.5 psig in accordance with ASME boiler and pressure 

vessel code, section IV, rules for construction of heating boilers. A 30 psig safety relief valve is shipped 

standard.

• Wall mount bracket
• Boiler has separate dedicated supply & return water connections to supply hot water directly to an Indirect 

tank.

• Boiler is equipped with an automatic 3 way diverting valve to allow Domestic Hot Water Priority operation.
• Boiler includes an internal pressure activated bypass loop to eliminate the need for primary secondary 

piping and includes an internal factory installed and wired circulator pump.

• Digital Boiler Control:

 

X

Control system is PCB integral controller with LCD digital display that includes graphical interface. 

 

X

Control senses supply water temperature and adjusts the boiler firing rate to deliver amount of heat 

needed.

 

X

Control can sense and display supply water temperature and indicate by icon when boiler is in central 

heating or domestic water mode.

 

X

Control can accept a wired Outdoor Air sensor and has field selectable reset curves

 

X

Control continuously monitors boiler during operation and standby modes. Control receives input data 

from dual temperature sensor, air pressure transducer, and outdoor air temperature sensors (when 

used) to adjust modulation rate accordingly.

 

X

Control can power and accept input from field supplied LWCO device.
