SAFETY INFORMATION
Carbon Monoxide Poisoning: Early signs of carbon monoxide
poisoning resemble the flu, with headaches, dizziness, or nausea. If
you have these signs, the log set may not be working properly. Get
fresh air at once! Have log set serviced. Some people are more
affected by carbon monoxide than others. These include pregnant
women, people with heart or lung disease or anemia, those under
the influence of alcohol, and those at high altitudes.
Natural Gas: Natural gas is odorless. An odor-making agent is
added to the gas. The odor helps you detect a gas leak. However,
the odor added to the gas can fade. Gas may be present even though
no odor exists.

CONNECTING TO GAS SUPPLY
WARNING: A qualified service person must con-
nect log set to gas supply. Follow all local codes.
Installation Items Needed
Before installing log set, make sure you have the items listed
below.
• piping (check local codes)
• sealant (resistant to Propane/LP gas)
• equipment shutoff valve
• test gauge connection
• adjustable (crescent) wrench or pliers
• sediment trap
• tee joint
• pipe wrench
CAUTION: Use only new, black iron or steel pipe.
Internally-tinned copper tubing may be used in certain
areas. Check your local codes. Use pipe of 1/2" diameter
or greater to allow proper gas volume to log set. If pipe
is too small, undue loss of volume will occur.
We recommend that you install a sediment trap in supply line as
shown in Figure 4. Locate sediment trap where it is within reach for
cleaning. Install in piping system between fuel supply and heater.
Locate sediment trap where trapped matter is not likely to freeze.
A sediment trap traps moisture and contaminants. This keeps them
from going into log set controls. If sediment trap is not installed or
is installed wrong, log set may not run properly.
Installation must include a equipment shutoff valve, union, and
plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge
hook up. NPT tap must be upstream from log set (see Figure 4).
IMPORTANT: Install equipment shutoff valve in an accessible
location. The equipment shutoff valve is for turning on or shutting
off the gas to the appliance.
Apply pipe joint sealant lightly to male NPT threads. This will
prevent excess sealant from going into pipe. Excess sealant in pipe
could result in a clogged burner injector.
WARNING: Use pipe joint sealant that is resistant to liquid
petroleum (LP) gas.

TESTING BURNER FOR LEAKS
1. Generously apply noncorrosive leak detection fluid to all
connections.
WARNING: Never check for gas leaks with
open flame.
2. Light the burner with the shutoff valve no more than half open
and holding a match slightly in front of the pan (see Lighting
Instructions,page 10).
3. Inspect all connections for bubbles, raw gas odor, or flame from
any area other than the burner (leaks). If leaks are detected,
shut off the gas valve immediately. Tighten, or reassemble the
loose connection(s) using pipe joint compound until burner
system is leak free.
4. When the burner is tested and leak free, observe the individual
tongues of flame on the burner. Note: The burner design includes
more ports on the outside of the bar. Make sure that all ports
are clear and producing flame evenly across the burner. If
any ports appear blocked, clear them by removing the burner
manifold and reaming the ports with a modified paper clip or
other suitable tool.
5. When finished testing, turn the gas shutoff valve OFF to ex-
tinguish all flames.
ADDING PAN MATERIAL
1. Open the bag of ash bed material (vermiculite) and spread it
evenly across the burner pan to the top. You may overflow the
front and sides of the pan to cover the entire pan and connect-
ing hardware. Do not cover GA9050A or GA9150A valve.
2. Open the glowing embers and evenly cover the ash bed material
(vermiculite) in the burner pan.
INSTALLING THE GRATE AND LOGS
1. Place the grate over the burner pan where the two outer hori-
zontal supports on the grate fit into the two pan positioning
notches in the rear vertical edge of the pan.
