LOCATING APPLIANCE
When locating this appliance, follow all
safety information on pages 2 and 3.
Do not use this appliance indoors. It is for
outdooruse only.Do notlocatethis 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.
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.
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.
UNPACKING
WARNING: Do not remove
the metal data plates attached
tothisappliance.Thedataplates
contain important warningsand
instructions.
1. Remove lava rock and log pack from
carton.
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.
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
directlyor inthe atmosphere,isnot covered
by the Limited Warranty on the back of this
manual. The warranty also does not cover
the following:
• weather damage caused by not using the
protective cover
• chips, cracks, or breakage caused from
dropping, dragging, or hitting firepit.
The surface of the firepit naturally contains
spaces,surface cracks, andvariations in color
and texture. The limited warranty does not
cover such surface imperfections.

Installation Items Needed
Beforeinstalling appliance,make sureyour
installer has the items listed below.
• piping (check local codes)
• sealant (resistant to propane/LP gas)
(May be pipe dope or Teflon tape)
• equipment shutoff valve *
• test gauge connection *
• adjustable (crescent) wrench or pliers
• sediment trap
• tee joint
• pipe wrench
• brass fitting(s) (depending upon gas sup-
ply plumbing)
*AnCSA/AGAdesign-certifiedequipment
shutoff valve with 1/8" NPT tap is an ac-
ceptable alternative to test gauge connec-
tion. Purchase the optional CSA/AGA de-
sign-certifiedequipmentshutoffvalvefrom
your dealer. See Accessory, page 10.
CAUTION: Use only new,
black iron or steel pipe. Inter-
nally-tinned copper tubing may
be used in certain areas. Check
yourlocalcodes.Usepipeof1/2"
diameter or greater to allow
proper gas volume to appliance.
If pipe is too small, undue loss of
pressure will occur.
We recommend that you install a sediment
trap in supply line as shown in Figure 3.
Locate sediment trap where it is within
reach for cleaning. Install in piping system
between fuel supply and patio firepit. Lo-
cate sediment trap where trapped matter is
not likely to freeze. A sediment trap traps
moistureandcontaminants.Thiskeepsthem
from going into appliance controls. If sedi-
ment trap is not installed or is installed
wrong, appliance may not run properly.
Installation must include an equipment
shutoffvalve, union,and plugged 1/8"NPT
tap. Locate NPT tap within reach for test
gauge hook up. NPT tap must be upstream
from appliance (see Figure 3).
IMPORTANT: Install equipment shutoff
valve in an accessible location. The equip-
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
fromgoing into pipe. Excess sealant inpipe
could result in a clogged burner injector.
CAUTION:Usepipejointseal-
ant that is resistant to liquid pe-
troleum (LP) gas.
