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
