 

Big John products are designed for OUTDOOR USE ONLY!  Only operate this equipment in a well-

ventilated area.  Do not use in garage, building, or other enclosed area.  Operation of this equipment 

indoors or in a poorly ventilated area may cause an explosion, fire, personal injury, or death. 

 

 

ONLY use the hose and regulator supplied with this grill from the manufacturer.  Any attempt to use 

parts found in a hardware store may result in the grill not functioning properly which could lead to an 

explosion, fire, personal injury, or death. 

 

 

DO NOT retrofit any equipment or accessories to the unit that are not part of the original equipment   

provided by Big John Grills & Rotisseries.  Replacement parts must be obtained from the             

manufacturer. Any attempt to change or modify this unit could result in an explosion, fire, personal 

injury to yourself or someone else, or death and will void your warranty. 

 

 

DO NOT touch or allow any contact with the sides, back, or top of grill after lighting. The unit is           

EXTREMELY HOT!  Allow the grill to cool completely before touching any metal surface. 

 

 

DO NOT operate grill within 12” of a combustible or non-combustible surface.  Provide adequate  

clearance and ventilation at all times. 

 

 

WARNING! Use of this grill in high wind conditions may result in poor burner operation (low flame, 

blowing out, flaring up, etc.).  Avoid these conditions if possible by repositioning grill.  If repositioning 

does not improve operation, discontinue use and turn off grill until conditions improve. 

 

 

DO NOT perform any maintenance until grill is completely cooled down. 

 

 

Liquid propane gas supply is easy to use and gives more temperature control than charcoal.    

 

 

This grill is a lava rock char broiler grill and therefore, factory supplied lava rock must be placed 

around burners for grill to operate properly.  DO NOT experiment with other materials.  Failure to use 

lava rock will result in grill malfunction and could result in personal injury or property damage.
