PILOT LIGHT REGULATION

The pilot lights on this griddle have been turned
off at the factory. Adjust pilot light flames as small
as possible, but high enough to light burner
immediately when burner valve is turned on high.

3

BURNER OPERATION (MODELS 615M,
624M, 636M, and 648M ONLY)

To ignite burners, turn burner valve knob to "HI"
position. Each burner is controlled by an individual
high-low, on-off valve. An infinite number of
temperatures may be obtained by turning the
burner valve knob to any position between high
and low.

BURNER ADJUSTMENT (MODELS 615M,
624M, 636M, and 648M ONLY)

1. Turn burner valve knob to "HI" position.

2. Slowly decrease opening of air shutters to
give a soft blue flame having luminous tips,
then slowly increase openings to a point where
the yellow tips disappear and a hard blue flame
is obtained.

3. Set the low adjustment to maintain
approximately 1/8" (3.175mm) high flame by
turning the screws inside the valve shafts when
the knob is turned to low.

BURNER ADJUSTMENT (MODELS 615T,
624T, 636T, 648T, TCHS & TSP ONLY)

1. Push dial in and set thermostat of one burner
to 450°F (229.9°C).

2. Observing flame through lighting hole, close
the air shutter to give a soft blue flame having
luminous tips and open to a point where the
yellow tips disappear, and a hard blue flame is
obtained. Repeat for all burners.

LIGHTING INSTRUCTIONS

When griddle is first lit, it will smoke until the
preservation oils and impurities are burned off.

1. Turn off main valve to unit and wait 5 minutes
to clear gas.

2. Turn off all knobs and pilot valves.

3. Turn on main valve and light all pilots.

4. Turn burner knobs to desired setting.

5. To turn burners off, turn knobs off.

LIGHTING INSTRUCTIONS (TCHS &
TSP SERIES)

1. Turn the thermostat knob(s) and pilot valves
to "OFF" position. CAUTION: If gas valves
have been on and gas has escaped through the
burners, turn unit off and wait 5 minutes to
clear gas.

2. Turn on pilot valve, depress and hold reset
button, light pilot, hold reset button for 60
seconds, or until pilot stays lit (repeat for all
pilots.)

3. Set thermostat(s) to desired temperature.

4. If burners do not light repeat steps 1 thru 4.

5. Turn off thermostats and pilot valves for
complete shutdown.

ADJUSTING BY-PASS (MINIMUM
FLAME-MODELS 615T, 624T, 636T, 648T,
TCHS & TSP ONLY)

Enough gas must be by-passed through the
thermostat to keep the entire burner lit after the
thermostat action has reduced the flame on the
burner. To allow accurate control of
temperature, be sure to set the by-pass
adjustment accurately. To make this adjustment,
proceed as follows.

1. Light the main burner(s).

2. Set the thermostat dial(s) at 350°F (174.9°C).

3. Allow the griddle to heat until the thermostat
action has cut down the flame on the
burner(s). This will take about 10 minutes.

4. Set the thermostat dial(s) at 150°F (64.9°C)
and observe flame.

5. The burner flame should now not exceed 1/8"
in height. If adjustment is needed, remove
dial(s), turn the by-pass adjustment screw on
the thermostat clockwise to decrease until the
flame over the entire burner is not more than
1/8" (3.175mm) in height.

NOTE: The griddles are equipped with standing
pilots and should be lit immediately after the gas is
turned on.

4

ADJUSTING THERMOSTATS (MODELS
615T, 624T, 636T, 648T, TCHS & TSP
ONLY)

The thermostat is a precision instrument. It has
been carefully calibrated at the factory. Field
recalibration is seldom necessary and should not
be done until the by-pass flame has been adjusted.
To measure griddle temperature use a reliable
pyrometer and proceed as follows.

1. Set dial to 400°F (202.4°C), lighting burner.

2. After burner has been on about 10 minutes,
check griddle surface temperature above
operating thermostat.

3. Continue to check temperature at 5 minute
intervals, until two successive readings are
within 5 degrees of each other. If your reading
is not within 10 degrees of the dial setting
400°F (202.4°C), recalibration is required.

4. Remove dial completely with "D" type stem.

5. Turn calibration screw clockwise to obtain a
lower temperature or counterclockwise for a
higher temperature. Each mark on retainer
represents 25°F (13.75°C).

6. Repeat steps for other thermostats.

ADJUSTING SAFETY PILOTS
(SERIES TCHS & TSP ONLY)

A rotor valve is provided to manually adjust pilot
flame size. "OFF" and "ON" positions are
indicated on valve. By slowly turning the
adjustment knob, a desirable pilot flame can be
obtained.

OVERNIGHT SHUTDOWN

Turn knobs to the off position to turn burners off.

OPERATING INSTRUCTIONS

SEASONING THE GRIDDLE HEATING
SURFACE (NON-CHROMIUM)

Clean the griddle surface thoroughly. After the
griddle has been thoroughly cleaned, it should be
seasoned to prevent food from sticking. Before
using, and after each thorough scouring, season
the griddle heating surface in the following
manner:

1. Turn the temperature control dial to 350°F
(174.9°C).

2. Using a clean cloth, not a spatula, spread a thin
film of cooking oil or fat over the griddle
cooking surface. This film should remain on
the hot griddle surface 1/2 hour.

3. Remove excess fat and wipe clean.

4. Apply another film of cooking oil over the hot
cooking area for another 1/2 hour, and again
remove excess fat and wipe clean. The griddle
surface should now be ready for use.

Even with careful seasoning food may, to some
extent, stick to the griddle cooking surface until
griddle plate is "broken in".

COOKING (MODELS 615T, 624T, 636T,
648T, TCHS & TSP ONLY)

Set the thermostat dial knob to the temperature
desired. After a short preheating period, the
thermostat will automatically maintain the
selected temperature.

GRIDDLE CARE (NON-CHROMIUM
SURFACES)

It takes very little time and effort to keep the
griddle attractive and performing at top efficiency.
If grease is permitted to accumulate, it will form a
gummy cake and then carbonize into a hard
substance which is extremely difficult to remove.
To prevent this condition, the following
suggestions for cleanliness should be followed.

1. After each use, scrape the griddle with a
scraper or flexible spatula to remove excess fat
and food. A waste drawer is provided for the
scrapings. If there is an accumulation of burned
on fat and food, the griddle should be
thoroughly scoured and reseasoned. Use
pumice or griddle stone while the griddle is
warm. Do not use steel wool because of the
danger of steel slivers getting into the food.

2. Daily-use a clean cloth and good non-abrasive
cleaner to clean the stainless steel body of the
griddle. Wipe the polished front with a soft
cloth.

3. At least once a day, remove the waste drawer
and wash in the same way as an ordinary
cooking utensil. The drawer is removed by
pulling forward, up and out.

GRIDDLE CARE (CHROMIUM
SURFACES)

It takes very little time and effort to keep this
Industrial Chromium griddle surface sparkling
clean and performing at top efficiency. DO NOT
allow grease to accumulate as it will carbonize and
becomes difficult to remove. To prevent this
condition the following cleaning suggestions
should be followed.

1. Remove excess oil and food regularly with a 4"
(100mm) wide Razor Sharp type scraper and
wipe surface with a damp cloth if desired.

2. Following the scraping, for end of the day
cleaning, a damp cloth and a non-silicated,
non-abrasive, non-chlorinated cleaner such as
Bon-Ami may be used to wipe surface clean,
followed by wiping with clean wet cloth.

3. Follow steps 2 and 3 from Griddle Care (Non­Chromium Surfaces) from page 4.

CAUTION

1. Never use Pumice, griddle stones, or
abrasives on the surface.

2 Never strike griddle surface with sharp
instrument or spatula edge.

3. Never use steel wool.

4. Never use commercial liquid grill cleaner
on the griddle surface.

5. Abusing surface voids the warranty.

GREASE PAN

A grease pan is located at the front and can be
removed from the front for cleaning. This pan
should be checked and emptied when necessary.
