Liquid propane (LP) gas is a petroleum product as are gasoline and natural gas. In normal tempera-
tures and pressures, LP gas is a gas. When moderate pressure is applied, inside a cylinder, LP gas
becomes a liquid. As the pressure is released the liquid readily vaporizes and boils off as a gas.
LP gas has no odor, but rather an odor additive so you can smell it.
Propane gas is denser than air, if a propane tank purges to relieve pressure build-up, the propane
will collect in low lying areas. These areas can be easily ignited and are highly flammable. Use
caution when dealing with a propane tank that may have recently self-purged.
DO NOT paint propane tanks any color other than white. Any alteration to tank color will result in
tank purging, fire, personal injury, or death.
Big John Grills & Rotisseries uses high quality Worthington Cylinders in 30 lb. and 40 lb. sizes.
These tanks are protected with a rust-resistant white powder coat finish.
Always keep the cylinder valve closed when not in use.
Cylinders are designed to function with the valve completely open or completely closed, there is no
in-between. Never open the valve just a “crack” or “half way”.
Always position the propane cylinder so that the connection between the valve and the regulator will
not cause any sharp bends in the hose.
NEVER store or use propane cylinders indoors.
Make sure the POL or QCC Connector is free from scratches or nicks which can cause gas leaks.
DO NOT store or use gasoline or other flammable liquids or vapors in the vicinity of a gas appliance.
DO NOT store extra liquid propane cylinders within the vicinity of a gas appliance.
DO NOT store a liquid propane cylinder in/on any part of an appliance not intended for such use.
Improper storage of a cylinder could lead an explosion, fire, personal injury, or death.
DO NOT store or lean items against unit surface or fuel cylinders while operating.
Shut off unit and all gas sources if the odor of unburned gas is detected. Make no attempt to use the
unit until gas leaks are fixed and/or the odor is accounted for.
Do NOT use a damaged, dented, or rusty LP cylinder or a cylinder with a damaged valve - replace
with a new one immediately.
Replacement LP tanks must match the regulator connection supplied with this grill and be a
minimum of 30 lb. capacity.
PROPANE SAFETY - GENERAL
LIQUID PROPANE TANK REQUIREMENTS
For tanks not purchased from Big John Grills & Rotisseries: check to be sure cylinders have been
tested within the past 5 years and have a D.O.T. certification. Your LP gas supplier can do this for
you.
All LP tank supply systems must have a collar to protect the cylinder valve.
All tanks used on Big John Grills equipment must be a minimum of 30 lb. size.
Tanks larger than 100 lbs. in size may require a POL for connection. Please call a Big John
Customer Service Representative if you are using a 100 lb. propane tank.
