Project Location:______________________________________
Contractor:___________________________________________
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.
CERTIFICATION AND APPROVALS:
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.
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:
XX Control system is PCB integral controller with LCD digital display that includes graphical interface.
XX Control senses supply water temperature and adjusts the boiler firing rate to deliver amount of heat
needed.
XX Control can sense and display supply water temperature and indicate by icon when boiler is in central
heating or domestic water mode.
XX Control can accept a wired Outdoor Air sensor and has field selectable reset curves
XX 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.
XX Control can power and accept input from field supplied LWCO device.

• Boiler Combustion System:
XXThe Gas valve is a modulating valve capable of firing from 100% input firing rate to 33% input firing rate.
XXInduced draft blower is variable speed. PCB uses air pressure transducer to vary blower speed.
XXBurners and manifold shall be constructed of stainless steel.
XXIgnition system shall be direct spark single rod flame sensing
• Primary Heat Exchanger:
XXBoiler’s primary heat exchanger is constructed of copper tube with copper fins, stainless steel support
plates and is covered with a high temperature protective coating.
• Electrical:
XX120 volts AC, 60 Hertz, 1-phase; less than 12 amps.
XXFactory wired 6-foot appliance cord with male plug end.
XXLow voltage terminal strip for Thermostat, and optional Outdoor Air Sensor,
DHW Indirect tank sensor and LWCO
• Optional Equipment:
XXFloor mounting stand
XXOutdoor Air Sensor
XXDirect Vent Termination Kit
XXLP Conversion kit
XXDHW Sensor kit for Indirect tank

• Constructed and hydrostatically tested for maximum allowable working pressure of 43.5 psig
(pounds per square inch gauge) (.30MPa) in accordance with ASME Boiler and Pressure Vessel
Code, Section IV, Rules for Construction of Heating Boilers.
• USA - Input rates are derated 4% for each 1000 ft (300m) above sea level,beyond 2000 ft. (600m).
• CANADA - Ratings above used for elevations up to 200 ft (600m) above sea level.
- For elevations between 2000 ft (600m) and 4500 ft (1350m), derate 10% using high altitude kit.
- Contact Provincial authority having jurisdiction for installations above 4500 feet (1350m) above
