Observe burner operation through the sight glass located on the combustion insert mounting flange. Normal burner operation should ignite smoothly, without evidence of coughing or huffing upon ignition. The burner flame should be a blue flame near the burner surface in a uniform flame pattern. Occasional yellow or white streaks are normal.

Serial Numbers including and AFTER GB13006174 and ALL EFR models

Note: On higher input models using metal fiber mesh burner a red glow from the burner surface is normal.
