Is electrical power supply to boiler on?
Is manual shut-off valve in gas supply pipe in open position? (Follow start-up procedures if you open gas line.)
If you have a manually ignited continuously burning pilotBe sure that it is burning. If not, see the start-up procedures in this manual

Soft lockout is reset after one hour if alarm reason disappears.
63Soft lockout: maximum number of recycles exceeded. (After main burner ignition)
64Soft Lockout - electronics failure. On-board self diagnostics detected error.
65Over temperature error. Sensor measured temperature in excess of maximum allowable limit.Hard lockout
