② PRE IGNITION TIME : 1 sec
→ To burn well, start the ignition before supplying gas.
③ POST IGNITION TIME : 9 sec ± 1sec
→ After the initial burning, the igniter will operate for 8 ~ 10 seconds in order to protect the burn from the initial
failure due to incomplete combustion.
④ POST PURGE TIME : 6 sec ± 1sec
→ After the burner stops, the fan will operate for 5 ~ 7 seconds to emit the exhausted gas from boiler.
