Mount burner in appliance
Welded flange-mounted burner
1. Place gasket over burner air tube and insert burner into appliance
opening. Secure in place with hardware supplied with appliance.
Universal flange or pedestal mount — these insertion methods
are intended only for negative overfire pressure. For pressur-
ized firing, you must obtain a burner with a welded flange,
designed for use with the specific appliance. Failure to comply
could result in severe personal injury, death or substantial
property damage.
