Low High or Medium Rack on Deck
Always place the pans symmetrically on the rack for best results. Keep the oven door closed as
much as possible. Excessive door opening will cool the front section of the oven and products
placed near the front are likely to bake slower. It is desirable to keep the front edge of the pans
at least several inches back from the inside of the door (when closed). Do not permit air from a
window or fan to blow into the oven; it will cause uneven heating.
Range Top
Consists of the various top arrangements, depending on specific model purchased:
12" x 24" hot plate controlled by indicating type three (3) heat switch or high temperature
thermostats. Temperature range 0-800°F (-18°C-427°C). Recommended: Stockpots and heavy
kettle work.
Round Speed Units, controlled by indicating type 3-heat switch. Temperature range is 0-800°F
(-18°C-427°C) Recommended: Light duty saucepans and small stockpots. Not Recommended:
heavy stockpots, heavy urns, or kettles.
12" x 24" or 24" x 24" grill plates, controlled by thermostats. Temperature range is 0-450°F (-
18°C -232°C). Recommended: All heavy and light frying. Set the thermostat dial at the desired
temperature. The red pilot light will be on until the desired temperature is reached. The pilot
light indicates when the plate is heating.
Care and Cleaning
The range should be thoroughly cleaned at least once a week in addition to the normal daily
cleaning to insure against the accumulation of foreign material. Keep inside of oven and metal
deck clean, particularly around door opening, door edges and at bottom of door opening so that
the door may close tightly. CAUTION: ANY OVEN CLEANER USED SHOULD BE MARKED:
"SAFE ON ALUMINUM."
Keep-drip pans under range top plates clean.
Keep hotplate and griddle surfaces clean.
Outside of range and top should be kept clean.
Electric equipment is clean and sanitary, but may become unsanitary if dirt is allowed to
accumulate on it. Take advantage of the clean, sanitary features of electric equipment, give it
the regular attention that it deserves, the same as any other highly perfected machinery, to
insure best results and continued high operating efficiency.
How to Order Parts
Be sure to give the SERIAL NUMBER of the range, when ordering parts. If a switch is required,
state for what size plate of the top surface or state if it is for the oven. Give description of other
parts.
