About the Trinity Ti (discontinued)
The discontinued Ti page markets the era of the TRINITY line with a focus on efficiency: NTI's copy says the combustion systems of the TRINITY mean little heat is wasted and less natural gas or propane is used. The series covered the Ti100–Ti200 wall-hung sizes, and the submittal, flow-switch cleaning and brazed-plate heat-exchanger cleaning documents that NTI still hosts reflect the brazed-plate-era service work on these units.
NTI lists the Ti under its discontinued products and directs buyers to its current lines. The I&O manual (doc 82419, dated 2015-10-13) is still public on ntiboilers.com, so a Ti owner can confirm model numbers and settings from the generation-specific document. Boilers.ca keeps this record so older installations can be identified and serviced against the correct manual.
