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 fi 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
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
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 off 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 Orifi ces
Top and oven orifi ces are fi 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
fl 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 fl ame
reaches the middle of a fl ash tube opening. This fl 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 off the burner nor show a
yellow tip.
Burner Gas/Air Adjustments
Ideal fl 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 fl ow and
ignite the burner.
