Mounting burner to appliance

  The universal flange supplied with G3B Gas burners is 

intended only for firing chambers with negative overfire 
pressure. The G3B burner must not be installed on a product 
that operates with a pressurized combustion chamber. Failure 
to comply could result in severe personal injury, death or 
substantial property damage.

Prepare the burner opening on the front of the appliance as shown in 
Figure 11.  See page 6 to determine the location of the flange on the burner 
air tube. Tighten the flange locking screws firmly.
