When first lighting the appliance, it will take a few
minutes for the line to purge itself of air. Once
purging is complete, the pilot and burner will light
and operate as indicated in the instruction manual.
Subsequent lightings of the appliance will not re-
quire such purging. Inspect the pilot flame (remove
logs, if necessary, handling carefully).
