NOTE: Before leaving the factory, the fryer was tested with oil in the frypot; therefore, it is necessary to clean the frypot
before adding frying compound. Rinse the frypot with clean water, then put some fryer cleaner on a damp cloth, full
strength, and wipe the entire frypot clean. Rinse it thoroughly and wipe dry. The fryer is now ready for use. If the fryer
does not have a stainless steel frypot and is not to be used immediately after cleaning, coat the entire frypot surface
with shortening or cooking oil to prevent rusting.

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.
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.

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
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 finish. Continue doing
this until the desired cooking temperature is reached.
Griddles
CAUTION
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 film. Wipe off any excess oil with a
cloth.
Part # 4519069 Rev 01(7 Feb 14)
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.
Page 21
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 flash fire 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:
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 finish.
Thoroughly rinse and dry with a soft cloth.
3. To avoid the appearance of fingerprints, several stainless
steel polishes are commercially available that leave an
oily or waxy film. 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 off 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 finish. Hot water or a
mild solution of bleach will sanitize stainless steel without ill
effect.
Some parts of cooking ranges use steel with untreated
surface finish (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.
Oven Interiors (Porcelain Enamel):
•
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.
Wipe away spills immediately.
Painted Finishes:
WARNING: Before cleaning the inside surface of a range,
unplug the power supply.
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.
Page 22
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 efficiency. 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 Rev 01(7 Feb 14)
MAINTENANCE AND CLEANING continued
1. After each use, clean the surface thoroughly with a grill
scraper or spatula. Wipe off 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 film 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
off 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
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 Orifices
Top and oven orifices are fixed 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
flame 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 flame
reaches the middle of a flash tube opening. This flame
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 off the burner nor show a
yellow tip.
Burner Gas/Air Adjustments
Ideal flames 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.
CAUTION: Do not use water on tops while they are hot, or
use ice to cool them.
3. If required, re-install the burner, turn on the gas flow and
ignite the burner.
1. While the surface is still slightly warm, wipe it with a clean
burlap cloth. Scrape off the burnt-on spillage.
Part # 4519069 Rev 01(7 Feb 14)
Page 23
MAINTENANCE AND CLEANING continued
4. Rotate the air shutter to obtain the following:
a. Open (star) burner – 12 mm stable, sharp inner blue
cones.
Fryers
1.
For daily cleaning, saturate cloth with full-strength
Fryer and Griddle Cleaner and wipe while warm - rinse
thoroughly
2.
Clean frypot at least once each week by filling to just
under full mark with water. Add Fryer and Griddle
Cleaner according to size of fryer (one cup per 35 lbs.
(16kg) of fat), bring to boil and continue boiling 10-15
minutes. If any other cleaner is used, add 2-4 oz. (59-118
ml) of white vinegar to final cold water rinse to neutralize
any trace of alkalinity remaining from compound.
6. If the burner flames are lazy and yellow in appearance,
increase primary air by opening the shutter.
3.
Clean exterior of fryer with full-strength Fryer and
Griddle Cleaner.
7. If poor burner performance persists, check for proper gas
pressure.
4.
Cover cooking vessel when not in use.
b. Hot tops, griddles – 8 mm stable, sharp inner blue
cones.
c. Knuckle burners – 8 mm stable, blue flame.
d. Charbroiler burners – 12 mm stable, blue flame.
5. If the burner flames are sharp and lift off the burner ports,
reduce the primary air by closing the air shutter.
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 five per cent less cooking time is a general rule. This
needs to be checked for first 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.
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.
Page 24
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.
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 off and allow it to cool
down when not in use.
