SAFETY  
while in operation.  
Ashes from trash or other combustibles  
could damage the burner system and  
affect its operation.Airborne ashes could  
set fires elsewhere and could cause se-  
vere burns or cause clothing to ignite.  
INFORMATION  
27. Do not operate this product around in-  
toxicated people. They could injure them-  
selves or others when using this product.  
(Continued)  
11. Do not operate near combustible ma-  
terials such as vinyl or wood siding on  
a home or other structure. They could  
be damaged or set on fire.  
28. Turn off gas at gas supply when this  
appliance is not in use.  
24. Do not use appliance if any gas controls  
have been exposed to or under water. Im-  
mediately call a qualified service techni-  
cian to inspect the appliance and to replace  
any part of the control system and any gas  
control which has been under water.  
29. Use protective cover (included) when  
appliance is not in use. Make sure ap-  
pliance is cool before using cover.  
12. Do not set combustibles on the edge of  
the appliance. Items such as paper cups,  
plates, and napkins could ignite.  
30. Turn appliance off and let cool before  
servicing or repairing.  
25. Do not allow water to contact the lava  
rock or logs. Water from rain, sprin-  
klers, toys, horseplay, etc. can damage  
lava rock and logs. When heated, they  
may crack, break, or even explode. This  
could cause severe injury.  
13. Do not operate this appliance where ex-  
cessive wind or drafts are present. The  
open flame may be blown outside of the  
appliance area. This could burn adults  
or children and cause clothing to ignite.  
31. Use only original replacement parts.  
This appliance must use design-specific  
parts. Do not substitute or use generic  
parts. Improper replacement parts could  
cause serious or fatal injuries.  
14. Do not use appliance below ground  
level. Propane/LP gas is heavier than  
air. If a leak occurs, propane/LPgas will  
sink to the lowest possible level.

UNPACKING  
Locate this appliance on a level, outdoor,  
noncombustible surface. Do not place this  
appliance on grass or dirt. This may prevent  
proper safety venting. Do not operate where  
wind or excessive drafts are present.  
WARNING: Do not remove  
the metal data plates attached  
tothisappliance.Thedataplates  
contain important warnings and  
instructions.  
Maintain proper clearance from combus-  
tible materials.  
• Never place this appliance directly on  
any combustible surface.  
1. Remove lava rock and log pack from  
carton.  
• Make sure combustible materials are at  
least 20 feet above appliance. This in-  
cludes tree limbs.  
2. Carefully lift firepit out of carton and  
gently place at site of installation.  
3. Check all items for any shipping dam-  
age. If damaged, promptly inform  
dealer where you bought the product.  
• Make sure combustible materials are at  
least 4 feet from sides of appliance.  
CHECK GAS TYPE  
Useonlypropane/LPgas.Ifyourgassupplyis  
not propane/LP gas, do not install appliance.  
Call dealer where you bought appliance.  
If your fuel source is a 20 lb. tank (com-  
monly used with gas grills), install tank  
securement bracket to concrete firepit be-  
foreinstallation(seeConnectingtoPortable

Note: Deterioration or damage due to severe  
weather conditions such as hail, hurricanes,

tank will stop gas flow. If this happens,  
close propane supply valve and open  
again slowly.  
CAUTION: Never connect ap-  
pliance directly to the propane/

quires an external regulator. In-  
stall the external regulator be-  
tween the appliance and the pro-  
pane/LP supply.  
Installation Items Needed  
9. Check all connections for leaks. Apply  
mixture of liquid soap and water to gas  
joints. Bubbles forming show a leak.  
Correct all leaks at once.  
Before installing appliance, make sure your  
installer has the items listed below.

(May be pipe dope or Teflon tape)  
10. Close propane/LP supply valve.  
Note: When operating with a full 20 lb.  
tank, your firepit will run between 5 and 9  
hours depending on flame setting and out-  
side temperature.

CHECKING GAS  
CONNECTIONS  
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.  
Test Pressures Equal To or Less Than  
1/2 PSIG (3.5 kPa)  
WARNING: Test all gas pip-  
ing and connections for leaks  
after installing or servicing. Cor-  
rect all leaks at once.  
1. The appliance must be isolated from the  
gas supply piping system by closing its  
individual equipment shutoff valve dur-  
ing any pressure testing of the gas sup-  
ply piping system at test pressures equal  
to or less than 1/2 psi (3.5 kPa).  
CAUTION:Usepipejointseal-

We recommend that you install a sediment  
trap in supply line as shown in Figure 5.  
Locate sediment trap where it is within reach  
for cleaning. Install in piping system be-  
tween fuel supply and patio firepit. Locate  
sediment trap where trapped matter is not  
likely to freeze. A sediment trap traps mois-
