Section 02
GRIDDLE GAS FLOW
SYMPTOMS
01. A flame is coming out of the air gate.
SYMPTOMS
01. Burner flames are yellow or irregular.
POSSIBLE CAUSES SOLUTION
01. Something is blocking the venturi
in the burner tube. This is not
allowing the propane to flow
through the burner, causing the
flame to back out the air gate.
Clean the burner assembly to remove
the obstruction. (Please reference the
Cleaning Your Griddle section of the
Care & Maintenance chapter.)
POSSIBLE CAUSES SOLUTION
01. Something is blocking the
air gate for the burner. This is
blocking oxygen from mixing
with the propane correctly to get
healthy flames.
Check the air gates in your burner. If
you have adjustable air shutters over
your air gates, make sure that they are
completely open. If your burners have
bug shields, clean any spider webs, soot,
or debris off the bug shield. Clean any
other obstructions out of air gates.

Troubleshooting
BURNER FLAME
PATTERN
Your griddle’s burners are designed
to mix oxygen and propane at a
rate that allows for optimal flames.
Should the burner’s holes, air
gate, or venturi get blocked, it will
affect the propane and air mixture,
causing low or inconsistent flames,
or flames coming from the air gate.
Healthy flames might have a few
flickers of yellow color

, then a
dark blue color

vibrant blue by the burner tube

POSSIBLE CAUSES SOLUTION
01. United States regulations require
that all griddle regulators contain a
flow limiting device for consumer
safety. This device measures the
amount of propane going through
the regulator to ensure the levels
are safe. If the flow rate through the
regulator is too high (a symptom
of a large leak), the flow limiting
device will trigger, restricting the
flow of propane to reduce the
chance of a dangerous fire. This
safety system can accidentally be
tripped by opening a propane tank
too quickly or opening the propane
tank when a burner knob is not in
the off position.
This safety system can be reset by
moving the burner knobs to the off
position, closing the propane tank,
and disconnecting the regulator from
the propane tank. Wait five minutes
to allow the pressure to dissipate,
then reconnect the regulator to the
propane tank and slowly open the
tank (it should take a full 30 seconds
to open half a turn). Ignite your
griddle as described in the Care &
Maintenance chapter.
02. LP gas cylinder is empty or low. Refill or replace the propane tank.
03. Obstructions in the burner, gas jets,
or fuel rail.
Clean the burner, jets, and gas
hose. (Please reference the Cleaning
Your Griddle section of the Care &
Maintenance chapter.)
04. Regulator stuck in safety position. Contact customer service for replace-
ment parts.
SYMPTOMS
01. Griddle will not achieve a high heat or heats unevenly.
02. Burner flames start strong, then immediately drop to low even when
burner is set to high position.
03. Flame height drops when a second burner is lit.
04. Flames do not extend the full length of the burner, or only run on one
side of the burner.
05. Burner flames are inconsistent.
