OPERATION
WARNING: THE BROILER AND ITS PARTS ARE HOT. BE CAREFUL WHEN OPERATING,
CLEANING OR SERVICING THE BROILER.
CONTROLS
Broiler
Infinite Load Switches
— Twoswitchesindependentlycontrolthefrontandrearheatingelements
in 208 and 240 volt models. The switch located on the left-hand side
of the switch panel controls the percent on-time of the two front
elements, and the switch located on the right-hand side of the switch
panel controls the two rear elements. The percent on-time of the
infinite load control varies from approximately 10% in the VERY LOW
position to 100% in the HIGH position.
3-Heat, 4-Position Switch
—
On 480 volt models, each of the two non-cycling 3-heat, 4-position
switches control independently the front and rear sections of the
broiler. Input varies from full power at the HIGH position (both
elements connected in parallel) to MED position (one element only
on) to LO position (both elements connected in series).
Grid Handle
— The distance of the grid surface from the elements is controlled by the
pull-and-release grid handle at the right of the broiler. This grid handle
locks in 13 positions over the 6" (152 mm) grid travel.
The operator can, by independent setting of each switch, provide a wide range of broiler temperatures
depending on the type and location of the broiling product.
Oven
3-Heat Switches
— Two switches (located on the right side of the switch panel, on each
side of the thermostat) independently control the top and bottom
heating elements. At HIGH position, the maximum element power
is utilized (elements connected in parallel); at MED position, only one
1
of the two elements is on (about /2 power); at LO position, the two
1
elements are connected in series (about /4 power); at the OFF
position, both elements are completely turned off.
Thermostat
— Controls the temperature of the oven from 175°F to 550°F (79°C to
288°C).
Indicator Light
— (Mounted next to the thermostat.) When lit, the thermostat is calling
for heat, and when off, indicates the desired temperature is
reached.

When the thermostat is turned on, it provides power to the two 3-heat switches, which in turn, according
to their setting, independently turn the top and bottom heating elements on and off. Thus, while the
thermostat controls and maintains the oven temperature around the desired set temperature, the
3-heat switches control the rate of temperature build-up.
BEFORE FIRST USE
Before using for the first time, clean the broiler or oven with detergent and water. Rinse thoroughly and
wipe dry with a soft clean cloth.
Seasoning (Oven Models Only)
Lightly, but thoroughly, coat the oven steel deck with cooking oil and allow it to season in the oven at
450°F (232°C) for 30 minutes to 1 hour. This seasoning will lessen sticking of spillage and inhibit rust.
USING THE BROILER
Preheating
At full input, the elements will heat to broiling radiance in approximately 5 minutes. The broiler will
saturate for full loading in 10 to 15 minutes at full input.
Grid
The grid is the V bar type, which permits easy scraping with a steak turner during operation. Drippings
from the broiling food go through the grid onto the drip shield and into the grease collector.
Grease Collector
The grease collector collects grease and waste which is diverted by the tilt of the drip shield. DO NOT
allow the grease collector to overflow. The grease collector should be emptied when three-quarters
full to reduce the possibility of spillage.
USING THE OVEN
Preheating
Set top and bottom 3-heat switches to HIGH. Set thermostat to desired baking temperature. The
indicator light will light and remain lit until the oven reaches temperature. The oven may be loaded
when the indicator light goes off the first time; however, it is desirable to allow the indicator light to go
on and off at least twice so the oven is thoroughly heated and will brown baked products evenly. After
the first cycle (oven indicator light on and off), set the 3-heat switches as desired for baking. (Refer
to TIME, TEMPERATURE & SWITCH SETTING CHART FOR BAKING.)

While it is recommended that you set the 3-heat switches to the HIGH position in order to preheat the
oven to the desired temperature, it is necessary for some baking products to turn the 3-heat switch
controlling the top elements to the MED or LO position in order to reduce the amount of radiant heat
applied to the particular product. This will eliminate burning of the top portion of the product.
Loading
Load the oven as rapidly as possible to prevent excessive heat loss. Place pans directly on the deck
and in rows back to front, beginning on the right, then the next row, etc., until oven deck is full. Do not
place pans closer to the door than 3" (76 mm). Do not let the pans touch the sides or back of the oven
or each other.
Baking
Approximate cooking times are given in recipe directions or are shown on the TIME, TEMPERATURE
& SWITCH SETTING CHART FOR BAKING shown below. When baking on the rack, it may be
necessary to set the bottom switch at HIGH.
Meat Roasting
Meat roasting is best performed in a balanced oven. Switch positions of HIGH and HIGH are
suggested, with the temperature control setting at the low temperature recommended by the American
Meat Institute and the Department of Agriculture. Top heat results in a well colored or carmelized finish
to meats. When roasting fowl and a heavily browned appearance is not desired, the top oven switch
should be set at MED or LO. The use of a meat thermometer is strongly recommended for all meat
roasting operations.

TIME, TEMPERATURE & SWITCH SETTING CHART FOR BAKING
This baking chart is a guide only. Recipes, mixing procedures, utensils and individual standards of
doneness, browning, etc., can result in variations in the precise time, temperature and switch settings
necessary to produce a satisfactory product.
High product quality can be obtained and maintained only if all phases of the baking operation are
properly performed. Variation in ingredients, under or overmixing, holding time before baking, etc., can
affect the texture, consistency and the basic quality of the product.
