Burnham Alpine ALP210B
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 Alpine ALP210B in practice
The ALP210B is the top of the Alpine sizes that can hang on a wall (floor-standing also allowed): 42–210 MBH input with 194 MBH DOE heating capacity and a 169 MBH net AHRI water rating at 95.0% AFUE (Table 1-5, Alpine I&O Manual 103448-12). It carries the stainless steel coil heat exchanger, Sage2.X outdoor-reset control, 5:1 modulation and identical NG/LP inputs of the rest of the line.
At 206 lb shipping weight it keeps the 1/2" FPT gas and 1" FPT supply/return connections of the smaller sizes (160 psi MAWP, 30 psi standard relief) and vents in 3" CPVC/PVC to 135 ft maximum equivalent on both intake and vent. Like the other ALP080B–ALP210B sizes it is rated to 2,000 ft elevation with a 2.5% derate per 1,000 ft above; a licensed contractor sizes, installs and commissions the boiler.
Best suited to
- Large homes and small multi-suite plants whose calculated load exceeds 150 MBH
- High-demand indirect-tank systems within the 210 MBH input ceiling
- Mechanical rooms where a 3" vent and intake run of up to 135 ft each fits
