notes: ** DOE Heating Capacity (ALP080 thru ALP285); Gross Output (ALP399 thru ALP500)
Maximum Working Pressure, Water - 30 PSI Shipped from Factory (std.); 50 PSI, 80 PSI and 100 PSI - Optional (ALP080 thru ALP285)
Maximum Working Pressure, Water - 50 PSI Shipped from Factory (std.); 80 PSI and 100 PSI - Optional (ALP399 thru ALP500)
Maximum Allowable Temperature, Water - 210°F, Maximum Firing Rate Target Setpoint is 190°F, Automatic Reset High Limit Setpoint
is 200°F and Manual Reset High Limit Setpoint is 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.
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.
