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 plumb- ing 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 (￿￿), fan speed (RPM), BMS input signal (0-10V), sensor temps and setpoints. Built-in outdoor reset feature saves energy- requires optional outdoor air sensor. Control also pro- vides 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, wonder- ing 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.

850:170MBTU • 500:100MBTU • 300:60MBTU 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 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 conden- sate 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 pri- mary 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.

12a. Flame Sense Electrode

After a call for heat, a seperate flame electrode moni- tors flame rectification. This helps to ensure proper carry over while also constantly monitoring the flame over 50 times every second.

13. Internal Tru-SealConnection

Allows the XFyre to be direct vented up to 200 com- bined equivalent feet (vent and air intake) in a hori- zontal or vertical vent system.

14. Smart Blower Technology

Utilizing a whisper quiet, all metal, technologically advanced combustion blower. Air and fuel are mixed precisely by the computer control center.

15. Mounting Feet

Built-in mounting feet located right under the center of gravity allows for quick and easy Tapcon anchor- ing.

16. Weather-Proof Jacket

Heavy gauge galvanized steel with a UV-resistant Polytuf powder coat finish is impervious to weather and corrosion. Raypak has one of the finest, top-of - the-line powder coat systems on the west coast regardless of industry. We laugh at a 1000 hour salt spray test. Independent test documentation available upon request.
