Burnham · Series
The Alpine is Burnham's condensing gas boiler line from U.S. Boiler Company: stainless steel coil heat exchangers, Sage2.X outdoor-reset controls and 95.0% AFUE across the ALP080B–ALP285B residential models, with the ALP399C commercial size rated 94.1% thermal efficiency — all documented in the public I&O manuals (103448-12, 106307-03).
Series facts
95.0% AFUE printed for every ALP080B–ALP285B model in the Alpine I&O ratings table (Doc 103448-12); the commercial ALP399C prints 94.1% thermal efficiency instead of an AFUE (Doc 106307-03). The official product page lists 95% AFUE with ENERGY STAR certification.
The Alpine is the high-efficiency gas boiler line of the Burnham brand, built and documented by U.S. Boiler Company at usboiler.net. Every ALP080B–ALP285B residential model prints 95.0% AFUE in the Alpine I&O ratings table (Doc 103448-12, 8/24): condensing stainless steel coil heat exchangers (ASME Section IV), outdoor-reset Sage2.X touchscreen controls, inputs identical on natural gas and propane, and minimum/maximum inputs that give 5:1 modulation. ALP080B–ALP210B hang on a wall or sit on the floor; ALP285B is floor-only.
The line also extends to commercial sizes: the ALP399C (with the ALP500C–ALP800C behind it) is documented in the Alpine Commercial I&O (Doc 106307-03) and prints a 94.1% thermal efficiency rather than an AFUE. Ratings apply sea level–2,000 ft, with the I&O manual's altitude rules above that (2.5% derate per 1,000 ft for ALP080B–ALP210B; ALP285B rated to 7,800 ft; high-altitude factory builds to 10,000 ft; the 399C rated to 10,100 ft). Venting is Category IV direct vent in PVC/CPVC, polypropylene or stainless steel with two-pipe and concentric terminations, at 60–135 ft maximum equivalent lengths by model.
U.S. Boiler Company publishes the Alpine manuals publicly, and Boilers.ca links the Alpine installation and operation manual here for owners and technicians. Boilers.ca documents the Alpine at model level — ALP080B, ALP105B, ALP150B, ALP210B, ALP285B and ALP399C — with ratings per the official tables. No official Canadian-sales statement was found, so canadianStatus stays 'unknown', even though Alpine-era units are installed in Canada (secondary evidence, not cited on this page).
Highlights
5-year part replacement warranty (for residential boilers under 300 MBH), per the official Alpine product page.
Models
One canonical page per model with input, output and efficiency kept separate.
Burnham
The Burnham Alpine ALP080B is the smallest Alpine: 16 to 80 MBH input at 95.0% AFUE with 5:1 modulation, wall-hung or floor-standing, vented in 3" CPVC/PVC (2" option to 60 ft) — the entry size of U.S. Boiler Company's condensing stainless steel line.
Burnham
The Burnham Alpine ALP105B fires 21 to 105 MBH input at 95.0% AFUE — 96 MBH DOE heating capacity and an 83 MBH net AHRI rating — in the wall-hung or floor-standing Alpine chassis, with the same 3" venting (2" option) as the ALP080B.
Burnham
The Burnham Alpine ALP150B is the mid-size Alpine: 30 to 150 MBH input at 95.0% AFUE with 136 MBH DOE heating capacity and a 118 MBH net AHRI rating, wall-hung or floor-standing at 182 lb, vented in 3" pipe to 135 ft intake / 100 ft vent.
Burnham
The Burnham Alpine ALP210B is the largest wall-hung-or-floor Alpine: 42 to 210 MBH input at 95.0% AFUE with 194 MBH DOE heating capacity and a 169 MBH net AHRI rating, vented in 3" pipe to 135 ft on both intake and vent.
Burnham
The Burnham Alpine ALP285B is the largest residential Alpine and the only floor-only size: 57 to 285 MBH input at 95.0% AFUE with 262 MBH DOE heating capacity and a 228 MBH net AHRI rating, vented in 4" pipe (3" option) and rated to 7,800 ft altitude.
Burnham
The Burnham Alpine ALP399C is the entry commercial Alpine: 80 to 399 MBH input printing 375 MBH gross output, a 326 MBH net AHRI water rating and 94.1% thermal efficiency (not an AFUE), floor-standing with 4" venting and a 10,100 ft altitude rating.

Services for Burnham boilers
No official Canadian-sales statement was found on the official pages, and the distributor finder U.S. Boiler Company publishes is US-oriented, so canadianStatus is recorded as 'unknown'. Boilers.ca documents the series and its models for information and service planning.
95.0% AFUE for every residential size (ALP080B–ALP285B) per the Alpine I&O ratings table; the commercial ALP399C prints 94.1% thermal efficiency in the Alpine Commercial I&O. The product page states 95% AFUE with ENERGY STAR certification.
U.S. Boiler Company publishes Alpine literature publicly on its Technical Literature page; Boilers.ca links the Alpine installation and operation manual (Doc 103448-12) for the ALP080B–ALP285B models and cites the Alpine Commercial I&O (Doc 106307-03) for the 399C. Installation and gas/venting work belong with a licensed contractor.
