XFyreT Condensing Modulating Boiler
- The Green Choice
Raypak’s new XFyreT is a natural extension of our successful
XThermT modulating vertical boiler line
(1,1.5, 2 Million BTUH). Raypak
offers new features not found in other mod-con style boilers and
combines these desirable features into one complete boiler package.
XFyre is the
only condensing boiler
(300 to 850MBTUH)
with CSA outdoor certification. Utilizing cabinet and control technology already
proven in over 250,000 Raypak pool heaters, the XFyre comes to
market as a seasoned veteran of outdoor environments. Mechanical
engineers, architects and building owners now have extreme installation flexibility, high efficiency, space saving footprint, zero side
clearance, direct vent capability, PVC venting and full service access.
Installers enjoy ease-of-commissioning, reliability, serviceability and
long-term performance. Small space, no longer a problem. Raypak’s
vertical water connections allow the units to be installed side by
side, further reducing the footprint on multi-boiler installations. Our
compact design makes it possible to install 6.8 million BTUH in
under 67 ft
2
of floor space, plus front and rear clearance. Tie them all
together with the built in Cascade Control and you have a boiler
system with a 40:1 turndown that operates at 94% thermal efficiency! This is an Xtreme green retrofit system.
XFyre Combustion System
Modulation is nothing new to Raypak. We have been honing our gas
modulation experience for over 50 years. The Raypak XFyre will precisely track the heating load with its built-in Computer Control
System and built-in outdoor reset function, eliminating costly overshooting. Utilizing the latest European technology for the combustion-components, the optimum fuel-air ratio is maintained throughout the entire range of the load-tracking operation. Our 5:1 turndown ensures efficiency is maintained throughout the firing rate and
actually increases during part load, right when you want it! The
XFyre automatically self-tunes to accommodate the widest range of
gas supply pressures. The high quality integrated blower-gas valve is
self-correcting and allows smooth operation with fluctuating gas
supply pressures. The Raypak XFyre is cutting edge technology with
atmospheric simplicity
.
Vent Flexibility
Category IV -CSA-certified 94% efficiency at
full fire for hydronic boilers and 95% for domestic water heaters
(Up to 99% at part load!)
When the job requires high efficiency, XFyre
meets your needs. Combined vent and combustion air duct length of up to 200 equivalent feet.
Vent your project in PVC, CPVC or Stainless.
XFyre is
CSA certified for all three. The XFyre ships PVC ready with
no extras to purchase!

1. Water Inlet
As low as 50°F entering. All copper and brass factory
installed vertical plumbing connections. Vertical
plumbing allows boilers to be installed side by side or
in tight places if need be. Male NPT connections.
2. Water Outlet
All copper and brass factory installed vertical plumbing connections. Male NPT connections.
3. Low Voltage Wiring Board
Allows easy front access to thermostat connections,
Outdoor sensor, DHW sensor,Alarm contacts and BMS
input signal
(0-10VDC)
. Built-in cascade control using
CAT 3 or CAT 5 computer network cables to connect
with the communication bus between boilers. Every
unit comes factory equipped with Cascade control.
Simply remove the front door for quick access and
daisy chain the boilers together.
4. Control Cover
Helps prevent sun damage to the LCD display and
protects the control panel from dust, dirt and water.
4a. Control Interface
Easy to use microprocessor control with a 2x20 LCD
scrolling display. Monitor flame strength
(mA)
, fan
speed
(RPM)
, BMS input signal
(0-10V)
, sensor temps and
setpoints. Built-in outdoor reset feature saves energyrequires optional outdoor air sensor. Control also provides indirect priority function. Full diagnostic control
constantly monitoring 18 events. Fault code history
records the last 10 fault events and can be recalled to
help with troubleshooting. Well thought out
ergonomic control pad gives tactile feedback to the
user. No need to second guess your actions, wondering if you have engaged the buttons or not. The user
is reassured with a tactile pop every time a button is
successfully toggled. Everything you need from set-up
to service is at your fingertips, and all in one location.
5. Air Fuel Ratio Gas Valve
XFyre uses a German, precision manufactured, main
gas valve considered by most to be second to none.
This high tech gas valve works in perfect unison with
the combustion air blower. The result is smooth and
quiet light-offs while delivering a 5:1 turn down.
With this much flexibility, XFyre is the right boiler for
almost any size job.
6. Intake Air Filter
Every XFyre comes standard with a front access,
removable Merv 8 media, combustion air filter
.
7. Manual Reset High Limit
8. Condensate Trap
The XFyre has a built-in condensate trap located at
the rear of the unit. The trap and the overfill condensate sensor are accessible through their own access
panel.
9. Vent Switch
Senses possible obstructions in the flue vent pipe.
10. Flow Switch
The XFyre keeps its flow switch safe and dry inside
the cabinet, which protects it during shipping and in
the boiler room.
11. “Duo” Style Heat Exchanger
The XFyre uses a combined 316L stainless steel primary and secondary heat exchanger. Weld-sealed
technology eliminates gaskets and o-rings. Special
glycol is not required for hydronic applications. ASME
Section IV constructed and stamped. National Board
registered.
12. Direct Spark Ignition
XFyre's state-of-the-art combustion control system
utilizes the finest dual electrode igniter to start the
combustion cycle. After ignition, the spark rod also
acts as a second flame sensor.

After a call for heat, a seperate flame electrode monitors flame rectification. This helps to ensure proper
carry over while also constantly monitoring the flame
over 50 times every second.
13. Internal Tru-Seal
T Connection
Allows the XFyre to be direct vented up to 200 combined equivalent feet (vent and air intake) in a horizontal or vertical vent system.
