Note: Deterioration or damage due to se-  
vere weather conditions such as hail, hurri-  
canes, earthquakes, or tornadoes, or discol-  
oration due to exposure to chemicals either  
directly or in the atmosphere, is not covered  
by the Limited Warranty on the back of this  
manual. The warranty also does not cover  
the following:  
HIGH ALTITUDE DERATE  
In the U.S.A., input BTU shall be  
derated 4% (1 orifice size) per 1,000  
feet for altitudes above 2,000 feet. In  
Canada, input BTU shall be derated  
10% (2 orifice sizes) at altitudes from  
2,000 to 4,500 feet.  
• weather damage caused by not using the  
protective cover  
LOCATING APPLIANCE  
• chips, cracks, or breakage caused from  
dropping, dragging, or hitting firepit.  
When locating this appliance, follow all  
safety information on pages 2 and 3.  
The surface of the firepit naturally contains  
spaces, surface cracks, and variations in color  
and texture. The limited warranty does not  
cover such surface imperfections.  
Do not use this appliance indoors. It is for  
outdoor use only. Do not locate this product  
in even a partially enclosed area, such as a  
garage or underneath a patio cover or ga-  
zebo. They could be damaged or set on fire.  
CHECK GAS TYPE  
Locate this appliance on a level, noncom-  
bustiblesurface. Donotplacethisappliance  
on grass or dirt. This may prevent proper  
safety venting. Do not operate where wind  
or excessive drafts are present.  
Useonlynaturalgas. Ifyourgassupplyisnot  
natural gas. Call dealer where you bought  
appliance.  
If your gas supply line does not have a gas  
supply shutoff valve, one must be installed.  
Maintain proper clearance from combus-  
tible materials.  
• Never place this appliance directly on  
any combustible surface.  
• Make sure combustible materials are at  
least 20 feet above appliance. This in-  
cludes tree limbs.  
• Make sure combustible materials are at  
least 4 feet from sides of appliance.  
Make sure to locate appliance where gas  
hose is out of traffic areas. This will help  
prevent people from tripping over the hose.  
This will also help prevent accidental dam-  
age to the hose.

ment shutoff valve is for turning on and  
shutting off the gas to the appliance.  
Apply pipe joint sealant lightly to male  
threads. This will prevent excess sealant  
from going into pipe. Excess sealant in pipe  
could result in a clogged burner injector.
