NOTES: DOE Heating Capacity (ALP080 through ALP285); Gross Output (ALP399)					*Gross output	** Thermal/combustion efficiency
Maximum Working Pressure - Water: ALP080-285=30PSI; ALP399=50PSI; 80PSI optional on all models
Maximum Allowable Temperature = 210˚ F
Boilers shipped set for natural gas; field adjustment for LP (see instruction manual)
For elevations above 2000 feet, reduce ratings four percent (4%) per 1000 feet above sea level
