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.
2. Turn the gas oven valve to ON.
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 eect.
Oven Interiors (Porcelain Enamel):
WARNING: Before cleaning the inside surface of a range, unplug the power supply.
• Wipeawayspillsimmediately.
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 eciency. 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 Orices
Top and oven orices 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.
Part # 4519069 (07/24/09)Page 22

6. Remove the thermostat dial, making sure not to disturb the setting.
7. Hold the calibration plate and loosen the two calibration locking screws.
8. Turn the calibration plate counter – clockwise to increase the oven temperature or clockwise to decrease it.
NOTE: One division of the calibration plate is equal to 25°F (14°C).
9. Hold the plate and tighten the screws.
10. Replace the thermostat dial.
11. Recheck the calibration as specied in this procedure to conrm 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.

CONVERSION INSTRUCTIONS
Servicing must be carried out by a competent person in accordance with the law.
WARNING: Turn o the gas supply to the appliance at the service cock before commencing any servicing work.
IMPORTANT: Test for gas soundness on completion of any servicing work.
The following instructions are intended to describe the operations necessary to convert equipment from operation on one gas family to that of another.
1. Ensure that all of the parts necessary to make the conversion have been supplied as follows:
a. Injector ttings ( One required for each main burner ).
b. Pilot injector ttings ( One required per pilot burner ).
c. Gas adjustment label ( One required per unit ).
If any of the required parts are missing, contact your Garland dealer before attempting to carry out the conversion.
NOTE: Conversion kits supplied for G31 gas will contain redundant ttings and markings covering both 37 mbar & 50 mbar gas supplies.
NOTE: Before doing so, refer to Table F (Table I for Australian Models) in this manual to ensure that the correct injector has been supplied for the gas supply being converted to.
4. Replace each pilot injector tting with the new tting supplied.
NOTE: There are two sizes of pilot injectors identied as follows:
a. # 32 (2nd family gases) Natural Gas.
b. # 23 (3rd family gases) Propane.
Ensure that you have the correct pilot injector before replacing.
Upon completion of all the above operations, follow the section in the manual on “Commissioning” and ensure that the setting pressure and all burner ame settings are adjusted accordingly.
Continuous product improvement is a Garland policy, therefore specications and design are subject to change without notice.
