APPLICATION:
Modulating Gas red water heating boiler for indoor installation. Approved for closet or alcove installations.
For use with natural or liqueed petroleum (LP/Propane) fuel gases, LP conversion kits available as option.
Wall mounted – optional oor stand available. All boilers are factory assembled with controls and wiring
and test red to ensure dependable performance. Boiler shall be certied for Category I and Category III
applications.
CERTIFICATION AND APPROVALS:
Copper tube heat exchanger is manufactured and tested in accordance with American Society of Mechanical
Engineers (ASME) and certied 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.
BOILERS INCLUDE:
• 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 ring 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 eld 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 eld supplied LWCO device.

• Boiler Combustion System:
X The Gas valve is a modulating valve capable of ring from 100% input ring rate to 33% input ring rate.
X Induced draft blower is variable speed. PCB uses air pressure transducer to vary blower speed.
X Burners and manifold shall be constructed of stainless steel.
X Ignition system shall be direct spark single rod ame sensing
• Primary Heat Exchanger:
X Boiler’s primary heat exchanger is constructed of copper tube with copper ns, stainless steel support
plates and is covered with a high temperature protective coating.
• Electrical:
X 120 volts AC, 60 Hertz, 1-phase; less than 12 amps.
X Factory wired 6-foot appliance cord with male plug end.
X Low voltage terminal strip for Thermostat, and optional Outdoor Air Sensor,
DHW Indirect tank sensor and LWCO
• Optional Equipment:
X Floor mounting stand
X Outdoor Air Sensor
X Direct Vent Termination Kit
X LP Conversion kit
X DHW Sensor kit for Indirect tank
