Operation status information relating to a start and end of the post purge is written in the storage means, and the operation status information is retained by the storage means even when power feed is stopped after the operation ends. When the operation is started, it is determined whether the power feed is stopped or not in a period from when the post purge is started to when the post purge is ended in a previous operation. Blowing operation for operating the blower before ignition of the burner is carried out based on a determination result. <P>COPYRIGHT: (C)2013,JPO&INPIT |
