Cleaning and Maintenance

General

Always turn ‘Off’ gas supply before cleaning.

This appliance is not water proof.

Do not use water jet spray to clean interior or exterior of this appliance.

Caution

Clean Target Top regularly. A clean appliance looks better, will last longer and will perform better.
Carbonised grease on cooking surfaces will hinder transfer of heat from cooking surface to food.
This will result in loss of cooking efficiency.

DO NOT use water on Target Top while this item is still hot as warping and cracking may
occur. Allow Target Top to cool down before cleaning.

NOTE:

 DO NOT use abrasive detergents, sharp scrapers, strong solvents or caustic detergents as

they could corrode or damage Target Top / Range.

 In order to prevent rust forming on Target Top, ensure that any detergent or cleaning

material has been completely removed after each cleaning. Appliance should be switched
'On' briefly to ensure target top becomes dry.

To keep your Target Top clean and operating at peak efficiency, follow procedures shown below:-

After Each Use

Clean Target Top with a stiff nylon brush or a flexible spatula to remove any build up of carbon.

Daily Cleaning

1. Thoroughly clean splash back, interior and exterior surfaces of Target Top with hot water, a mild
detergent solution and a soft scrubbing brush.

2. Brush Target Top (cast iron) with a soft bristled brush followed by wiping with a cloth to prevent
accumulation of carbon.

3. Remove drip tray and clean with a mild anti bacterial detergent and hot water solution using a soft
bristled brush. Dry drip tray thoroughly with a dry cloth.

4. Dry target top thoroughly with a dry cloth and polish with a soft dry cloth.

Weekly Cleaning

NOTE:

 If Target Top usage is very high, we recommend that weekly cleaning procedure is carried

out more frequently.

 Ensure protective gloves are worn during cleaning process.
 DO NOT use harsh abrasive detergents, sharp scrapers, strong solvents or caustic

detergents as they will damage Target Top.

 DO NOT use water on Target Top while it is still hot as warping may occur. Allow castings

to cool down before cleaning.

Target Top

a. This should be kept clean of any build up of spillage’s of food. Provided cast iron work surface is

regularly used it will maintain itself in good condition with no special cleaning requirements
required.

b. Clean any food residue and spillage from channels around centre casting and main plates before

use.

16

Cleaning and Maintenance

c. DO NOT use water on castings while they are still hot as cracking may occur. Should it

be necessary to clean castings, allow castings to cool and then remove for cleaning. Clean using
a soft cloth moistened with a mild detergent and hot water solution and a scrubbing brush. Dry
thoroughly with a dry cloth.

d. Remove drip tray and clean with a mild anti bacterial detergent and hot water solution using a

soft bristled brush. Dry drip tray thoroughly with a dry cloth.

Stainless Steel Surfaces

a. Clean exterior surfaces of Target Top with hot water, a mild detergent solution and a soft

scrubbing brush. Note that gas control knobs are a push fit onto gas control valve spindles and
can be removed to clean front control panel.

b. Baked on deposits or discolouration may require a good quality stainless steel cleaner or stainless

steel wool. Always apply cleaner when appliance is cold and rub in direction of grain.

c. To remove any discolouration, use an approved stainless steel cleaner or stainless steel wool.

Always rub in direction of grain.

d. Dry all components thoroughly with a dry cloth and polish with a soft dry cloth.

Periodic Maintenance

NOTE: All maintenance operations should only be carried out by a qualified service person.

To achieve the best results cleaning must be regular and thorough and all controls and mechanical parts
should be checked and adjusted periodically by a qualified service person. If any small faults occur, have
them attended to promptly. Don't wait until they cause a complete breakdown. It is recommended that
the appliance is serviced every 6 months.

Gas Control Valve Re-Greasing

Gas control valve should be dismantled and greased every 6 months to ensure correct operation.
To carry out this operation;-

a. Remove gas control knobs from gas tap spindles by pulling knobs

away from control panel.
b. Remove drip tray from appliance.
c. Remove two screws on underside of control panel, securing the

control panel to the hob and remove control panel from front of

appliance.
d. Remove 2 screws holding shaft plate to gas control body and

remove control shaft and plate. (See Fig 6). Note orientation of

shaft for correct re-assembly.
e. Using needle nose pliers or similar, pull out gas control

spindle, again noting its orientation.
f. Apply a suitable high temperature gas cock grease or

lubricant such as ROCOL - A.S.P (Anti scuffing paste) /

Dry Moly Paste to outside of spindle. (See Fig 7).
g. Replace spindle and re-assemble gas control in reverse

order.
h. Refit control panel to appliance and secure with 2
