NTI Trinity TFT201 in practice
The TFT201 is one of the eight wall-hung condensing models in NTI's discontinued Trinity TFT line, documented in the Trinity Tft 60-399 Installation and Operation Instructions (99984535, V.2024-04-08). Table 2-1 lists it at 20–200 MBH CSA input modulation with a 185 MBH DOE heating capacity and a 160 MBH Net I=B=R rating. The manual's 95% AFUE figure covers the TFT60 through the TFT285.
The model connects with 1-1/4" NPT male water connections and a 1/2" NPT male gas connection, and the manual specifies 3 in vent/air-inlet piping. The discontinued TFT page lists 3" runs up to 150 ft each side, a with-water weight of 180 lb and 4.9 gallons of boiler water content for this size. NTI lists the TFT under Discontinued and describes the current TFTN as built on the same platform with a redesigned control, so TFT owners and technicians rely on the 99984535 manual and the discontinued page's submittals.
Best suited to
- Light-commercial and large residential loads near 200 MBH
- Projects wanting 1-1/4" water connections and 3" venting
- Cascade installations using the TFT's lead-lag control
