Series facts
Fulton's VANTAGE is a condensing firetube hydronic boiler with a high-mass duplex-stainless vessel and true dual-fuel capability: the page prints natural gas, propane and #2 oil, with the control auto-loading the fuel profile for the fuel in use. Sizes are VTG-2000, 3000, 4000, 5000 and 6000 (2,000,000–6,000,000 BTU/hr).
The page prints 'ultra-high efficiency … high thermal efficiencies' and carries separate AHRI Thermal Efficiency tables for gas and for #2 oil in the Specs tab, whose per-model values are not re-typed in Boilers.ca's research file. A lifetime thermal-shock warranty is printed on the page.
The current VANTAGE brochure is public and linked from this hub; the page's documents tab also carries the I&O and specification PDFs.
