Upon completing the gas line connection, a small
amount of air will be in the lines. When fi rst lighting the
pilot light, it will take a few minutes for the lines to purge
themselves of this air. Once the purging is complete,
the pilot and burner will light and operate as indicated
in the instruction manual. Subsequent lighting of the
appliance will not require such purging.
