RBI Futera III 1000 in practice
RBI's Futera III product page prints the 1000 row as 1000 MBH (293 kW) input and 853 MBH (250 kW) boiler output, in a 39" × 25.125" × 61.5" cabinet (991 × 638 × 1562 mm) with a 735 lb (333 kg) shipping weight.
The row lists Category I 9", Category II 7" and Category IV 6" flue options, a 8" air intake, 1" gas and 2" water connections. The Futera III is a gas-fired copper 4-pass heat exchanger (160 psi) with HEATNET 3.0 integrated controls, Modbus/LonWorks/BACnet integration and full modulation with 4:1 turndown, per the product page.
RBI rates the Futera III line at 85.6% AHRI Boiler Efficiency. Boilers.ca prints the rating-table row exactly as published and does not estimate values RBI does not print; the I&O manual (FTIII-IOM-15) and the series brochure are linked from the official literature library. No official Canadian-sales statement was found, so canadianStatus stays unknown.
