After one hour there will be an ignition attempt. If the blockage has been removed, the heater will return to normal operation. If the blockage remains, the heater will return to a one hour lock out cycle. If this problem occurs, homeowners must not attempt to operate or repair the heater themselves but contact a qualfied service agency.
