RBI Futera XLF 4000 in practice
RBI's Futera XLF product page prints the 4000 row as 4000 MBH (1172 kW) input and 3480 MBH (1020 kW) boiler output, in a 31.125" × 29.125" × 69" cabinet (791 × 740 × 1753 mm) with a 1570 lb (712 kg) shipping weight.
The row lists Category I 12", Category II 14" and Category IV 10" flue options, 2" natural-gas and 1 1/2" LP connections (where printed) and a 4" water connection. RBI describes the Futera XLF as a 2,500–10,000 MBH copper 4-pass heat exchanger (160 psi) with HEATNET 3.0 controls, Turbo Pilot ignition, Modbus/LonWorks/BACnet integration and 5:1 turndown.
RBI rates the Futera XLF line at 85.9% AHRI Boiler Efficiency. Boilers.ca prints the rating-table row exactly as published; the I&O manual (XLF-IOM-17) and series brochure are linked from the official literature library. No official Canadian-sales statement was found, so canadianStatus stays unknown.
