         BOILERS AND WATER HEATERS
   Introducing PRIMERA, an exciting and cost effective
change in hydronics and domestic water heating to meet
the demands of the owner, engineer, contractor, and
maintenance manager.

   PRIMERA        combines       reliable,   high-efficiency
performance with ease of installation; including a small
footprint, venting versatility and 1" available clearances.
PRIMERA is also maintenance friendly with single-panel
access to all controls and gas train components.


  FEATURES

  Concentric finned-copper heat exchanger                                                 Air
has integral angular baffles to capture and
transfer heat for long and efficient service
life. This eliminates the need for “V” baffles;   Exhaust
components that can shift out of place on
other boilers and cause a reduction in effi-
ciency and potential combustion problems.


  Furnace-braze-welded header and tube joints
result in greater tensile strength than the surrounding
base metal. The all copper or cupro-nickel design
eliminates rolled or gasketed joints common in designs
                                                                                                                   Cold Inlet

 Multi-pass heat exchanger design moderates pressure drop and provides greater consistency and
control of water velocity, which is essential to maximizing the boiler’s service life.


 Vertical heat exchanger orientation offers a small footprint. PRIMERA boilers fit through 32"doorways
across the entire product range.

 Premix burner automatically balances the fuel to air ratio under varying vent pressure conditions. Low
NOx, metal-fiber-matrix burner is centrally located for even heat distribution across the exchanger.

 Hot surface ignition system and flame monitor is vertically oriented to protect against damage from
shipment, handling and condensation during start-up.

 Digital temperature control with LED readouts for ease of viewing. Temperature settings and operational
parameters are fully programmable. Connectable to a building management system through optional
MODBUS interface.

  Water heaters are ASME section IV, part HLW stamped. Water heaters up to 1,000,000 Btu/h are single
stage with an option for stage firing. Water heaters above 1,000,000 Btu/h are fully modulating with 3:1
turndown. Boilers are ASME section IV, H stamped. Boilers are two-stage up to 1,000,000 Btu/h and fully
modulating above 1,000,000 Btu/h. Turndown is 3:1 except for the 399,000 Btu/h boiler which is 2:1.

  Accessibility for service: All burner and control components are accessible in seconds by removing a
single top pan. Flip-up control panel cover provides protection and yet allows easy access to the digital
temperature control, flame and low-water resets, main power switch and fuse.
