NTI Trinity FTG2200
The NTI Trinity FTG2200 fires 235 to 2200 MBH at 95.6% thermal efficiency with a 2,103 MBH heating capacity and a 1,829 MBH Net AHRI rating — the mid step of NTI's 2,000 MBH-class FTG fire-tube boilers at 1,710 lb.

NTI Trinity FTG2200 in practice
NTI lists the FTG2200 at 235 to 2200 MBH input with 95.6% thermal efficiency, a heating capacity of 2,103 MBH and a Net AHRI rating of 1,829 MBH. It shares the large FTG class with the 2000 and 2400: 1,710 lb on the page, 3 in grooved water connections, a 1 1/2 in NPT male gas connection, and 8 in air inlet and flue runs up to 150 ft.
The 2200 keeps the 235 MBH minimum fire of the FTG2000 while adding 200 MBH of ceiling, and its thermal efficiency eases from 96% to 95.6%. The FTG Installation and Operation Manual (99985422) lists the class at 2,140 lb with water against the page's 1,710 lb and requires the 10% Canada altitude derate between 2,000 and 4,500 ft, which matters for plants planned above that elevation.
Best suited to
- Commercial hydronic plants whose demand calculation lands between 235 and 2200 MBH
- Buildings stepping between the FTG2000 and FTG2400 without changing connections or venting
- Plants wanting fire-tube capacity near 2,200 MBH from a single NTI boiler
