XFyre® Condensing Modulating Boiler - The Green Choice
Raypak’s new XFyre® is a natural extension of our successful XTherm® 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 out- door 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 instal- lation 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 ft2 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 efficien- cy! 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 pre- cisely track the heating load with its built-in Computer Control System and built-in outdoor reset function, eliminating costly over- shooting. Utilizing the latest European technology for the combus- tion-components, the optimum fuel-air ratio is maintained through- out the entire range of the load-tracking operation. Our 5:1 turn- down 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 domes- tic water heaters (Up to 99% at part load!) When the job requires high efficiency, XFyre meets your needs. Combined vent and combus- tion 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!
