DANGER! 
Natural gas burners are started, stopped, and monitored independently of 
the dryer controls using Eclipse
TM
 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
