Series facts
The retired page copy says '96% efficient'; the printed page table gives 96% for EP-80/EP-110, 95% for EP-150/220/299, 96.1* for EP-301 and 96.5* for EP-399 (asterisks as printed, N/A Energy Guides). The LP-549 submittal prints 'Up to 96.4% AFUE' and 'Up to 96.5 Thermal Efficiency'.
HTP's retired Elite Premier page describes a 'low mass boiler with a 316L stainless steel heat exchanger' available in 'seven different models ranging from 80,000 to 399,000 BTUs', suitable for radiant flooring, fan coils, baseboards, snow melt and domestic hot water via an indirect tank, with a 10 to 1 turndown and SCAQMD Rule 1146.2 compliance. The printed page table lists EP-80 (8,000-80,000, 96), EP-110 (11,000-110,000, 96), EP-150 (15,000-150,000, 95), EP-220 (22,000-220,000, 95), EP-299 (30,000-299,000, 95), EP-301 (30,000-301,000, 96.1*) and EP-399 (40,000-399,000, 96.5*).
LP-550 Table 4 supplies the per-model rating rows used on the model records: heating capacity (74/100/138/204/277/289/385 MBH), shipping weight (108/113/126/164/211/256 lb), water content (1.4-3.7 gal), dimensions, 160 PSI MAWP with a 30 PSI relief valve, the 928 SIT control and venting in 3" or 4" pipe (4" or 6" on the 220-399) up to 275 combined feet. LP-558 prints the connection sizes: 1" for the 80/110/150/220, 1-1/4" for the 299/301 and 1-1/2" for the 399 (LP-550 Table 4 prints 1" NPTF in the 399 cell).
The Elite Premier is retired: HTP's discontinued-products index lists the 'Elite Premier Boiler' and the documents page states verbatim 'This model has been discontinued, please refer to the below documentation for 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-550.
