GENERAL 

Although all gas connections on the grill are leak 
tested at the factory prior to shipment, a complete 
gas tightness check must be performed at the 
installation site. Periodically check the whole 
system for leaks following the procedures listed 
below.  
 
If the smell of gas is detected at anytime you should 
immediately check the entire system for leaks. 

 
BEFORE TESTING

 

Make sure all packing materials have been 
removed from the grill, including the burner tie-
down straps. 
 

 

 
Make a soap solution of one part liquid detergent 
and one part water. You will need a spray bottle, 
brush, or rag to apply the solution to the fittings.  
 

TO TEST 

1.  Turn off all control valves, and turn on the gas 

supply. 

 

2.  Apply the soap solution to all pipe fittings, from 

the natural gas regulator and supply valve or 
from the LP cylinder up to and including the 
pipe that connects to the burners. Soap bubbles 
will appear where a leak is present.  

 
3.  If a leak is present, immediately turn off the gas 

supply and tighten the leaky fittings.   

 
4.  Turn the gas back on and recheck.  
 
5.  If gas continues to leak from any of the fittings, 

turn off the gas supply, and contact customer 
service at 1-800-554-5799. 

 
Only those parts recommended by the 
manufacturer should be used on the grill. 
Substitutions will void the warranty.  
 

GAS FLOW CHECK

 

Each grill burner is tested and adjusted at the 
factory prior to shipment. However, variations in the 
local gas supply may make it necessary to adjust 
the burners. The flames of the burners should be 
visually checked. Flames should be blue and stable 
with no yellow tips, excessive noise or lifting.   
 
If any of these conditions exist, first check to see if 
the burner is blocked by dirt, debris, spider webs, 
etc.  
 
If the burner is free of blockages, you will need to 
fine-tune the air/gas mixture by moving the 
adjustment bolt (See the image on page 15).   
 
Remember it is better to make several minor 
adjustments as opposed to a single large 
adjustment.

 

   

It is handy to keep a spray bottle of soapy water 
near the shut-off valve of the gas supply line. 
Spray all the fittings. Bubbles indicate leaks. 

 

Disconnected LP cylinders must have threaded 
valve plugs tightly installed, and must not be stored 
in a building, garage or any other enclosed area. 
 
The gas must be turned off at the supply cylinder 
when the unit is not in use. 
 
If the appliance is stored indoors the cylinder must 
be disconnected and removed from the appliance.  
Cylinders must be stored outdoors in a well-
ventilated area out of reach of children. 
 

 

WARNING

 

Always check for leaks after every LP tank change. 
 

 
 
 
 

 

WARNING  

 

 

Do not use the grill until all connections have 
been checked and do not leak.  
 
Do not smoke while leak testing.  
 
Never leak test with an open flame.
