NTI Boilers Trinity Vmax (discontinued)
The Trinity Vmax was NTI's wall-hung condensing boiler series built around a down-fired fire-tube stainless steel heat exchanger with a built-in primary loop and pump and dedicated indirect-tank connections. NTI lists the Vmax — VM110 and VM153 heat-only versions plus VM110P and VM153P Vmax Plus — as discontinued.

About the Trinity Vmax (discontinued)
The discontinued Vmax page highlights what made the line unusual: a built-in primary loop with an integrated circulating pump and dedicated indirect tank connections, so the boiler shipped as a near-complete near-boiler package. The heat-only VM110 and VM153 fired 13.8–110 and 15.4–154 MBH at 95% AFUE, and the Vmax Plus VM110P and VM153P added DHW through the tank connections with flows of 2.6 and 3.6 GPM at a 77°F rise.
The series vented in PVC, CPVC or polypropylene — 2" runs to 100 ft on the VM110-class sizes and 3" only on the VM153-class sizes — and shared the Argus display operating guide with the Tx and FTV lines. NTI now lists the Vmax under Discontinued; its published specifications remain on the product page for owners and technicians servicing these units.
