The Elite FT (EFT) is HTP's retired stainless steel fire-tube condensing boiler line: seven models EFT-55 through EFT-399 with 11,000-399,000 BTU/hr printed input ranges, a vertical fire-tube heat exchanger, 5:1 turndown on the 55-199 generation and 10:1 on the later 285/399, cascade support for up to eight boilers and a 12-year heat-exchanger warranty.
Series facts
LP-392/LP-391 print 'an AFUE rating up to 96.3% and thermal efficiency up to 93.2' for the 5:1 models. The retired page prints EFT-285 at 95.1% AFUE and EFT-399 at 97.1* thermal efficiency (as printed); LP-659 prints the same 95.1/97.1 figures for the 10:1 generation.
HTP's retired Elite FT page describes 'a high efficiency heating boiler for residential and commercial applications' that 'comes in two models, ranging from 285,000 to 399,000 BTUs' with 'up to a 95.1% AFUE rating with up to a 10 to 1 turndown ratio', a stainless steel heat exchanger, 200 ft combined vent in 3" PVC, cascade support for up to eight boilers and a twelve year warranty. The printed page table lists EFT-285 at 285,000 Btu/hr, 95.1% AFUE and 203 lbs, and EFT-399 at 399,000 Btu/hr, 97.1* thermal efficiency and 298 lbs (N/A energy guide).
LP-387's technical specifications table supplies the full seven-model rating set used on the model records — inputs (11,000/55,000 through 79,800/399,000 in the 5:1 table), heating capacity (51-367 MBH), shipping weights (125-298 lb), water content, dimensions, copper SWT connections, 30 or 80 PSI MAWP and venting — while LP-657 prints the on/after-10/30/17 10:1-generation 285/399 inputs (28,500/285,000 and 39,900/399,000) used for those two model records. LP-392 prints the 5:1 generation's 'AFUE rating up to 96.3%', ASME 'H' construction, National Board listing, ETL listing, ANSI Z21.13/CSA 4.9, a 12-year heat-exchanger warranty, cascade up to eight boilers and 0-10V BMS input.
The Elite FT is retired: HTP's discontinued-products index lists 'Elite FT Heating Boiler' and the EFT documents page remains as archived support. Boilers.ca records the line with productStatus 'discontinued' and canadianStatus 'unknown' — no official Canadian sales statement was found. Owners should have the unit serviced by a licensed contractor against LP-387 (or LP-657 for the later 285/399).
Highlights
LP-392/LP-391 print a twelve (12) year limited warranty on the complete heat exchanger assembly; the retired page prints 'The Elite FT comes with a twelve year warranty'.
