* All tanks are tested at 320 psig working pressure.
** Based on No. 2 fuel oil with a heat content of 140,000 Btu's per gallon at 80% thermal efficiency. Above 2,000 altitude, input
ratings should be reduced 4% for each 1000' above sea level.
ALL DIMENSIONS IN INCHES/mm
*Model numbers followed by the suffix "A" indicates the optional A.S.M.E. tank construction.
