OPERATION
FIRST TIME USE
Before lighting the Broiler for the first time, ensure that all package materials including the stainless steel
protective film and moisture absorption packs have all been removed from the cooking grates and drip
trays before lighting.
Use warm soapy water and a cloth to wipe down and remove any dust or metal filings that may have
settled during manufacturing.
CORRECT ASSEMBLY
Before first time use ensure that all heat baffles, infrared hoods and cooking grates have not moved
during transport. Incorrect alignment may affect the operation of the broiler.
LIGHTING INSTRUCTIONS
1. Turn the Control knob from position “off” to “Pilot” .
2. Depress control knob and hold it down and light pilot immediately with “piezo ignitor”.
Note: The pilot can been seen through the “pilot viewing hole”.
3. Once the pilot has lit, continue to hold in the control knob for 10 seconds, before slowly releasing.
(Verify that the pilot is still lit once the control knob has been released, if not repeat step 3 & 4).
4. Turn gas control knob to the “Hi-flame” position. The burner will then ignite.
5. If the pilot becomes extinguished, repeat the above procedure.
SHUTDOWN INSTRUCTIONS
1. Turn the gas control knob to the “"off" position.
2. Allow broiler to cool down before cleaning.

MAINTENANCE
DAILY CLEANING
Warning: Ensure the appliance is off and the parts are cool to touch.
Warning: Cooking by-products are collected in the channel at the front of the Broiler and drain in to a
removable grease drawer. Cooking by-products may also fall directly in to the grease drawer. Ensure the
front channel, drainage hole and grease drawer are cleaned regularly. Ensure the grease drawer is always
in position when cooking.
CLEANING BROILER GRATES, INFRARED HOODS AND BURNERS
After each use, clean the open Broiler grates with a sharp grill scraper and/or brush as necessary to
remove any excess debris.
Warning: Never use liquids to clean the Broiler grates in the installed position. Remove Broiler grates for
thorough cleaning in liquid.
Warning: Empty the grease drawer as necessary, clean, dry and replace. Ensure the grease drawer is
always in position when cooking.
Broiler grates, infrared hoods, are all positively located and may be removed (in sequence) for service and
cleaning, burners are not removable. Note: After cleaning, ensure the components are dry and re-
assemble in reverse order – ensure all items are correctly and positively located. Never operate the Broiler
without the infrared hoods & cooking grates installed.
Cleaning must be regular and thorough to ensure safe and efficient operation of the equipment and to
prevent flare-up. The amount of usage and the type of products being cooked will largely determine how
often complete cleaning is necessary - it is the operators responsibility to assess this.
To clean the items, use a suitable detergent and warm water and scrubbing brush. Repeated scrubbing
will be necessary if deposits are heavy and baked on.
CLEANING STAINLESS STEEL
Regularly wipe the surface with hot water and detergent. Rinse the washed area with a wet sponge and
clean water and wipe the area dry to prevent streaking. Follow this process and wash a small area at a
time to prevent chemical residue and streaking.
Stainless steel may discolour if overheated. These stains can usually be removed using an appropriate
powder/paste. To scrape off heavy deposits of grease and oil, use only wood or plastic tools as
necessary.
Note: Never use steel wool to clean stainless steel.
Note: Damage may occur if chemicals not suitable for stainless steel are used.
USE ONLY SUITABLE CHEMICALS AND OBSERVE ALL
MANUFACTURER SAFETY REQUIREMENTS FOR SAFE HANDLING
AND USE.
