Add Suffix “N” for Natural Gas or Suffix “P” for LP Gas Models.
notes:
** DOE Heating Capacity (ALP080 thru ALP285); Gross Output (ALP399)
Maximum Working Pressure, Water - 30 PSI Shipped from Factory (std.); 50 PSI - Optional
Maximum Allowable Temperature, Water - 210°F
Boilers are factory shipped as Natural Gas builds and have to be field adjusted for LP gas application. Refer to ‘System Start-
Up Section of this manual for detailed procedure.
For elevations above 2000 Feet, ratings should be reduced at the rate of four percent (4%) for each 1000 Feet above sea level.

Ratings shown are for installations at sea level and elevations up to 2000 Feet. For elevations above 2000 Feet, ratings should be
reduced at the rate of four percent (4%) for each 1000 Feet above sea level.
