RC Convection Ovens
Power failure: In the event of an electrical power failure, do
not operate this oven. It is gas operated, but has electrical
features, motor and door switches. A wiring diagram is
attached to the rear of the appliance.
Start Up:
1. Turn the power switch to the COOK position.

3. Turn the thermostat to the designed setting.
Cool Down:
1. Turn the thermostat and oven valve OFF.
2. Return the power switch to OFF.
3. Turn the oven valve OFF.
Motor Care:
The motor on a convection oven is equipped with sealed,
self-lubricating ball bearings and is maintenance free. It will
give durable service when treated with ordinary care. Here
are some operating notes.
1. When the motor is operating, it is cooled internally by
air entering the rear of the motor case, provided proper
clearance has been allowed. Ensure that rear of range has
minimum 25 mm clearance around perimeter.
2. Because the blower wheel is in the oven cavity it is at the
same temperature as the oven. If the motor is stopped
while the oven is hot, heat from the blower wheel is
conducted by the shaft to the motor armature. This can
dramatically shorten motor life.
3. It is recommended that, at the end of the bake or roasting
period when the oven may be idle or ready for shutdown the oven door be left open. Use the COOL-DOWN
position on the fan switch, which keeps the fan operating
for at least 20 minutes.
CAUTION: Never turn the fan OFF when the oven is HOT.

MAINTENANCE AND CLEANING
Proper maintenance, cleaning and care of cooking
equipment is an important part of any program and will keep
it in good operating condition. These notes provide a code
of good practice for users to maintain a regular cleaning
schedule
Seasoning
Griddles
1. Remove any factory applied protective material by
washing with hot water and a mild detergent or soap
solution.
2. Apply a thin coat of cooking oil to the griddle surface in
the proportion of about one ounce per square foot of
surface area. Spread this over the entire surface with a
cloth to create a thin lm. Wipe o any excess oil with a
cloth.
3. Light the burners and set them at the lowest setting.
Some discoloring will occur when heat is applied to the
steel.
4. Heat the griddle slowly for 15 to 20 minutes. Then wipe
away the oil. Repeat this procedure three times or until
the griddle has a slick, mirror-like nish. Continue doing
this until the desired cooking temperature is reached.
CAUTION
Do not go to HIGH (on valve control) or 230°C (on thermostat
control) during the seasoning period. If it is seasoned
properly, the griddle will not require re-seasoning. If,
however, the griddle is overheated and product begins
to stick to the surface, it may be necessary to repeat the
seasoning process.
Part # 4519069 (07/24/09)Page 19
MAINTENANCE AND CLEANING continued
Cast Iron Top Grates And Ring Grates
1 Move the grates from the range and wash them in warm
water with mild soap. Then dry them with a clean cloth.
2. Immediately after drying, season the grates lightly with a
non-toxic oil (a light vegetable oil, liquid or spray).
WARNING: Do not season top grates while they are still on
the range top. A ash re may result.
3. After seasoning, replace the top grates on the range and
operate all the range top sections on LOW.
4. Allow the sections to operate for 20 minutes before using
pots and pans on them.
CAUTION: To grates required seasoning whenever they
have been cleaned. Failure to season them after cleaning will
cause rusting.
Cleaning
Raw Steel Finishes:
Some parts of cooking ranges use steel with untreated
surface nish (i.e., hot tops, griddles, springs, doors etc.).
These parts can react with moisture and rust or corrode. This
is normal and not considered a factory defect.
2. Use a paste of water and mild scouring powder if
necessary, but always with the grain, not against it.
Stainless steel is polished in one direction, so clean in
the same direction as the grain to preserve the nish.
Thoroughly rinse and dry with a soft cloth.
3. To avoid the appearance of ngerprints, several stainless
steel polishes are commercially available that leave an
oily or waxy lm. Do not use them on surfaces that will be
in contact with food.
4. Stainless steel may discolor if overheated. These stains
may be removed by vigorous rubbing with a scouring
powder paste or Scotchbrite pad.
CAUTION: Use only stainless steel, wooden or plastic tools
only if it is necessary to scrape o heavy deposits of food and
oil. On no account use ordinary steel scrapers or knives for
this purpose as iron particles may become imbedded in the
stainless steel and lead to corrosion. Never use steel wool on
stainless steel surfaces. It destroys the nish. Hot water or a
mild solution of bleach will sanitize stainless steel without ill
eect.
Oven Interiors (Porcelain Enamel):
WARNING: Before cleaning the inside surface of a range,
unplug the power supply.
• Wipeawayspillsimmediately.
Painted Finishes:
1. Wipe away spills immediately.
2. Allow equipment to cool before cleaning exterior
surfaces. Wipe exposed, cleanable surfaces with a
mild detergent and hot water when the surfaces have
cooled, not before. Remove stubborn residue spots with
a lightweight non-metallic scouring pad and dry the
surface thoroughly with a clean cloth.
Stainless Steel Finishes:
1. For routine cleaning, use hot water and a mild detergent.
Wash a small area at a time. Tackling a large area allows
water to evaporate, leaving chemicals that lead to
streaking. Rinse the washed area with a clean sponge
dipped in a sanitizer, and wipe it dry with a soft cloth
before it can dry by evaporation.
1. Before cleaning an oven interior, remove the racks and
guides. Clean the oven racks and guides with a mild soap
and warm water solution, or pass them through a dish
washer.
2. Clean the porcelain enamel surface daily, using a soap
solution. At least once a week clean the oven thoroughly
with a detergent or any commercial oven cleaner
recommended for use with porcelain enamel, but only
when the oven is cold.
Griddles
CAUTION: Do not use water on griddle tops while they are
hot. Do not try to cool a griddle with ice. This will warp the
plate and may cause it to crack.
To maintain evenly cooked, perfectly browned griddle
products, keep the griddle free from carbonized grease.
Carbonized grease hinders the transfer of heat from the
griddle surface to the food product. This results in uneven
browning and loss of cooking eciency. Carbonized
grease also clings to griddle foods, giving them a highly
unsatisfactory and unappetizing appearance. To keep a
griddle clean and maintain it at peak operating performance,
follow this procedure.
Part # 4519069 (07/24/09)Page 20
MAINTENANCE AND CLEANING continued
1. After each use, clean the surface thoroughly with a grill
scraper or spatula. Wipe o debris left over from the
cooking process.
2. Daily: Clean the surface with a grill brick or pad. Remove,
empty and clean the grease container thoroughly.
3. Weekly: Clean the surface well with a grill brick or pad.
Rub with the grain of the metal while it is still warm. A
detergent may be used on the plate surface to help clean
it, but make sure it is removed. After cleaning, cover the
surface with a thin lm of oil to prevent rusting.
4. Use a non-abrasive cleaner to remove discoloration.
Before using the griddle again it must be re-seasoned. On
models without a side grease container, keep the griddle
drain tube to the grease container clear.
CAUTION: The griddle plate is steel, but the surface is
relatively soft and can be easily scored and dented by the
careless use of a spatula. Dents, scratches and gouges in the
surface will cause food to stick.
Open Top Burners
1. Periodically, remove burners and clean them with soap
and hot water.
2. Soak the burner in a bucket of hot soapy water and brush
o any burnt-on grease or debris. Make sure the burner is
thoroughly dry before re-installing it on the range.
3. If the burner ports are blocked or plugged with grease,
clear them with a wire brush or pointed instrument.
Cast Iron Top Grates And Ring Grates
1. Clean with hot water and a mild detergent. Use a wire
brush to remove baked-on food particles.
2. Lightly coat with vegetable oil to help prevent rusting.
CAUTION: To grates required seasoning whenever they
have been cleaned. Failure to season them after cleaning will
cause rusting.
Cast Iron Even Heat Hot Tops And
Spectro-Heat Tops
CAUTION: Do not use water on tops while they are hot, or
use ice to cool them.
1. While the surface is still slightly warm, wipe it with a clean
burlap cloth. Scrape o the burnt-on spillage.
2. Remove the plate and wash it with soap and hot water.
Dry it and apply a thin coating of oil to inhibit rusting.
Excessive use of water could damage the surface and the
controls below.
NOTE: The surface of Cast Iron Hot Tops and Spectro-Heat
Tops will tone (a blue-brown discoloration) from heat. This
does not diminish the cooking operation and is not a defect
Adjustments
Top and Oven Orices
Top and oven orices are xed and cannot be adjusted. A
proper rate is attained if the gas supply pressure is correct.
Use the 1/8” NPT manifold pressure tap to check the pressure.
A well-adjusted air shutter will provide for a distinct blue
ame over the entire port area of the burners when they are
operating at full rate.
Pilot Adjustment
Individual pilot adjustment valves are mounted on the range
top manifold.
1. Adjust the open burner pilot so that the tip of the ame
reaches the middle of a ash tube opening. This ame
may show a slight yellow tip, particularly when used on
propane gas.
2. The pilot burner for the griddle or top burner should
proved rapid ignition of the burner, but should not
impinge on any part of the burner. When correctly
adjusted, it should not lift o the burner nor show a
yellow tip.
Burner Gas/Air Adjustments
Ideal ames vary depending on the type of burner
considered., although a sharp blue blame at full rate is
typical.
To adjust burners, proceed as follows:
1. On the burner (star, Griddle, knuckle, broiler, oven burners)
locate the air shutter. This found at the inlet to the burner
venturi.
2. Loosen the lock-nut so that the air shutter turns freely.
3. If required, re-install the burner, turn on the gas ow and
ignite the burner.
Part # 4519069 (07/24/09)Page 21
MAINTENANCE AND CLEANING continued
4. Rotate the air shutter to obtain the following:
a. Open (star) burner – 12 mm stable, sharp inner blue
cones.
b. Hot tops, griddles – 8 mm stable, sharp inner blue
cones.
c. Knuckle burners – 8 mm stable, blue ame.
d. Charbroiler burners – 12 mm stable, blue ame.
5. If the burner ames are sharp and lift o the burner ports,
reduce the primary air by closing the air shutter.
6. If the burner ames are lazy and yellow in appearance,
increase primary air by opening the shutter.
7. If poor burner performance persists, check for proper gas
pressure.
CONVECTION OVEN (RC) – OPERATING TIPS
The following notes are a guide for the use of convection
ovens.
1. Set oven temperatures 5°C to 10°C lower than recipes
specify for the use of standard ovens. The cooking time
may also be less, depending on the product, but two
to ve per cent less cooking time is a general rule. This
needs to be checked for rst time.
2. Cooking time and oven temperate will vary depending
on the size of the load, the temperature of the product,
mixture of the recipe and, in particular, the moisture
content of the product.
8. Never place pans directly on to the oven bottom. Always
use the lowest rack position which allows the air to
circulate within the over cavity.
9. Load and unload food as quickly as possible to prevent
an excessive drop in temperature.
10. Avoid the use of warped pans because level pans bake
more evenly.
11. Do not use a deep pan for shallow cakes, cookies, etc., as
circulation across the surface is essential for even cooking
and browning.
3. When a satisfactory cooking time and temperature for a
particular product is established, make a record for future
use.
4. Preheat the oven before use. To reach 175°C takes about
15 minutes. For the best results, pre-heat the oven for 30
minutes to allow for thorough heat saturation.
6. Set the product in the center of the oven for the best heat
circulation.
7. A convection oven will hold three 450mm x 660mm sheet
pans, six 305mm x 500mm x 63mm steam table pans or
one 530mm x 450mm x 175mm roast pan with cover.
12. To prevent excessive shrinkage, roast meats at a low
temperature: 120°C to 160°C.
13. When re-thermalizing frozen products, pre-heat the
oven 10°C higher than the cooking temperature to
compensate for heat loss during and after loading.
NOTE: The thermostat must be returned to the cooking
temperature after loading.
14. To conserve energy, turn the oven o and allow it to cool
down when not in use.

Thermostat Calibration
Oven
CAUTION: Remember to check the bypass every time
the oven is recalibrated (refer to the entry on Thermostat
bypass).
Recalibration of the oven thermostat is seldom necessary
and should not be attempted unless the cooking results
denitely prove that the thermostat is not maintaining
the temperatures to which the dial is set. Use a reliable
temperature indicator when checking the oven temperature.
To calibrate an oven thermostat, follow this procedure.
Part # 4519069 (07/24/09)Page 24
SERVICING continued
1. Place the thermocouple of the test instrument in the
center of the oven.
2. Light the oven, set the thermostat to 400°F (204°C) and
wait 15 minutes for the oven temperature to stabilize.
3. Check the temperature at 5 minute intervals until three
successive readings are within ±5°F (±3°C) of each other.
4. If the temperature is not within ±20°F (±8°C) of the
thermostat dial setting, refer to Figure 10 to recalibrate
using this procedure.

9. Hold the plate and tighten the screws.
10. Replace the thermostat dial.
11. Recheck the calibration as specied in this procedure to
conrm that the correct adjustment has been made.
Fryer
The same observation made about oven thermostats applies
to fryers. That is, recalibration of the thermostat is seldom
necessary. If experience with the cooking results proves that
the temperature at which the dial is set is incorrect, follow
this procedure to re-calibrate the thermostat. Use a reliable
thermometer only or, preferably, a pyrometer.
1. Suspend the thermometer or thermocouple in the
middle of the fry tank about 2” (76mm) below top level of
oil.
2. Allow the burner to cycle four times.
3. When the burner cycles OFF after the fourth cycle,
compare the reading of the thermometer or
thermocouple with the thermostat setting.
4 If the two readings are not within ±5°F (±3°C) of one
another, loosen the two set screws in the thermostat
knob and set the pointer of the thermostat to agree with
the reading of the test thermometer or thermocouple.
5. Tighten the set screws on the thermostat knob after
resetting the pointer.
