and to insure no debris is accumulating.
Main burner should light smoothly from pilot and burn with a blue flame with a minimum of yellow tips. After 5 minutes
of operation the burner screen will become radiant and the flame will soften and turn orange. If the burner screen does not
become radiant after 5 minutes of operation it must be cleaned (see burner cleaning procedure below).
Main burner must be free from any debris accumulation that may effect burner operation (see burner cleaning procedure
below).
