2. BURNER SETUP
• Prior to turning appliance on visually inspect re feature to ensure debris such as leaves or other combustible material
has not collected inside the feature which could burn and emit embers once the re feature is turned on. Each burner
should have a ame height of approximately 12” – 15” from the top of the pan.
• Each burner should be adjusted as required so that the ame size at each burner is similar in appearance to each
other.
• Install decorative rock or glass on top of the “burner support” and burner assembly. Do not completely cover/obstruct
the burner.
3. START UP
h. Perform all above listed safety checks before start up. Before operating smell all around the appliance area for gas
odors and next to the oor because some gases are heavier then air and will settle on the oor.
i. Ensure any person standing close to the re feature is aware you will be turning the re feature on prior to actually
turning it on.
j. Turn on the unit at the switch or control panel. The igniter should start glowing followed shortly by the gas valve
opening and re igniting.
k. If the unit does not light the rst time, there may be air in the gas line. Turn o unit and allow to sit for 30 seconds
B. AUTO IGNITION INSTALLATION
3. GAS CONNECTION
a. Before beginning, ensure the gas line is turned OFF.
b. NOTE: The air mixer must be installed to use liquid propane. The “holes” on the air mixer should always face DOWN,
away from the burner and pan. The air mixer should be installed immediately below the burner. (FIG 2)
c. Run 1/2” gas line to the bottom connection on the black box
d. Use pipe dope/joint compound on ALL threaded ttings EXCEPT ared ttings.
e. Keep pipe length and elbows to a minimum to eliminate unnecessary pressure drops.
f. The use of a corrugated gas line can cause unwanted noise.
g. Connect pressure regulator in line before the Auto Ignitor Box. The regulator should be installed horizontally. The
directional arrow should point away from the gas source and towards the gas valve.
h. Conrm no more than 1/2 PSI on at the regulator inlet. If pressure is too high regulator will shut o gas ow. If above
1/2 PSI you can install a second regulator to reduce the pressure to 1/2 PSI before the included regulator.
i. Verify all gas connections are tightened securely. ALWAYS perform leak tests and make repairs as needed.
j. DO NOT daisy chain the gas lines. (See Section D)
k. A shut-o valve must be installed at each re feature or valve. The primary gas valve must be located where they can
be easily accessible so that the gas can be shut o quickly in case of an emergency.

4. ELECTRICAL CONNECTION
a. Power Requirements
1. Auto ignition requires minimum 12.6 Volts DC, up to 36 Volts DC at the transformer
2. The included transformer steps down to 12.6 V DC
3. Installer should check voltage after installation to ensure proper values
b. Connections
1. There are two wire connections on the side of the black box at the tranformer. Connect to power source using
wire nuts.
2. These are DC power connections. You must match polarity when connecting. Connect red wire to red wire and
black wire to black or blue wire.
3. Wrap wire nuts with electrical tape or some means to prevent moisture from getting in. Make sure wire nuts are
positioned away from the bottom of the burner assembly.
4. Connect ground from incoming power to ground lug (If required by local codes)
5. Do not “daisy chain” electrical lines (See Section D
4. CHECK SYSTEM

C. OPERATION & MAINTENANCE
the power back on. This could potentially take two-three cycles but then should re consistently.
4. MAINTENANCE & CARE
• Periodically clean the burner assembly with a wet cloth or cleaning solution to remove carbon build-up. Frequency of
the cleaning will depend on usage.
• Periodically inspect the underside of the burner assembly for any signs of excessive temperatures.
• Keep the ignition and temperature probe locations clear of media or debris.
• Check that all gas connections are tight.
• The burner assembly should be covered and protected from snow and ice. The burner should not be operated in high
wind conditions.
• Visually inspect burner holes for debris/insect infestation Clean burners as necessary using compressed air.
• Use the system! If the feature has been inactive for an extended period, turn re feature on to ensure proper
operation.
• Inspect the gas line regularly. If the line shows evidence of excessive abrasion or wear or if the line is damaged, it must
be replaced before use.
• Inspect the burner before each use of the appliance. If there is any evidence that the burner is damaged, it must
replaced before operating.
D. TROUBLESHOOTING
COMMON ISSUES/MISTAKES
• Check line connections - do not daisy chain gas or electrical connections (see Section C)
• Check gas pressure for natural gas and propane (see Section B)
• If using with propane gas - ONLY use with air mixer correctly installed. (See Fig 2) ½ “ air mixer for propane includes
stamped marking for gas ow direction. Air mixer is not required with Natural Gas.
• Check electrical voltage. Minimum volts at the transformer connection is 12.6 VDC.
• Check electrical connections. Auto ignitor uses DC power. Connect positive/red to positive/red/brown and negative/
black to negative/black/blue.
• Check ground connections. (if required)
• Upon completing the gas line connection, a small amount of air will be in the lines. When rst lighting the burner, it
will take a few minutes for the lines to purge themselves of this air. Subsequent lighting of the appliance should not
require such purging.
a. LED Indicators
1. There are three LED indicators on the side of the valve next to the probe connection
2. The LED indicators are an obsolete component and can be disregarded
DO NOT DAISY CHAIN DO RUN INDIVIDUAL LINES
FIGURE 5: DAISY CHAIN GUIDE
HOW TO PERFORM A LEAK TEST
a. Prepare a leak testing solution of soapy water by mixing in a spray bottle one part liquid soap to one part water.
b. Make sure all the control knobs are in the OFF position.
c. Turn on the gas.
d. Apply the leak-testing solution by spraying it on joints of the gas delivery system. Blowing bubbles in the soap
solution indicates that a leak is present.
e. Stop a leak by tightening the loose joint or by replacing the faulty part with a replacement part recommended by the
manufacturer.
f. Turn the control knob back to the full OFF position.
g. If you are unable to stop a leak: Please consult a gas specialist. Shut o the gas supply to the re pit and release
pressure in the hose and manifold. Call/consult an authorized gas appliance service technician or an liquid propane
gas dealer. Do NOT use the appliance until the leak is corrected.
Perform a leak test at least once a year whether the gas supply has been disconnected or not. Whenever any part of the gas
system is disconnected or replaced, perform a leak test. As a safety precaution, remember to always leak test
your re pit outdoors in a well-ventilated area. Never smoke or permit sources of ignition in the area while doing a leak test.
Do not use a ame, such as a lighted match to test for leaks.
