About the Trinity FTV (discontinued)
The discontinued FTV page shows a combi line — FTV110C, FTV150C and FTV190C, firing 11–110, 15–150 and 19–190 MBH — plus heating-only FTV110, FTV150 and FTV190 siblings at 95% AFUE. The FTV used a vertical fire-tube heat exchanger in 439 stainless steel with a programmable display, quick-connect components and universal vent connections with an embedded test port.
The combi models' published DHW flow was 2.7, 3.6 and 4.5 GPM at a 77°F rise, and the series vented in PVC, CPVC or polypropylene with 2" runs to 100 ft on the two smaller sizes. NTI now lists the FTV under Discontinued; its published specifications remain readable on the product page, and owners can still download the FTV heat-exchanger cleaning instructions shared with the Vmax and FTG lines.
