DANGER! Natural gas burners are started, stopped, and monitored independently of the dryer controls using EclipseTM Bi-Flame burner controls. Read and follow the burner control manufacturer’s operating and safety instructions and applicable NFPA© (National Fire Protection Association) codes in addition to your local rules and regulations. The Eclipse Bi-Flame model 6500 Dual Burner Monitoring System (instruction manual no. 826, 05/03) should be included with the dryer.
