BURNER OPERATION (MODELS 615MA,
624MA, 636MA, and 648MA 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 615MA,
624MA, 636MA, and 648MA ONLY)
1. Turn burner valve knob to the "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 615TA,
624TA, 636TA, 648TA, TCHSA & TSPA 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.
NOTE: The griddles are equipped with standing pilots
and should be lit immediately after the gas is turned on.
LIGHTING INSTRUCTIONS (TCHSA & TSPA
SERIES)
1. Turn the thermostat knob(s) and pilot valves to
the "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 the pilot valve, depress and hold the reset
button, light the pilot, hold the reset button for 60
seconds, or until the 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 615TA, 624TA, 636TA, 648TA, TCHSA
& TSPA 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.
