INSTALLATION
Important
Your attention is drawn to the latest GAS SAFETY (INSTALLATION & USE) REGULATIONS 2000.
This appliance MUST be installed by a competent person in accordance with these and any other relevant
regulations. Users, too, should be aware of the regulations governing the use of gas appliances,
particularly with respect to the need for regular servicing.
Your attention is drawn to the requirement that those parts, which have been protected by the
manufacturer or his agent, are not to be adjusted by the installer.
Before Installation
Before commencing installation, remove all packaging materials from the appliance. It is suggested that
any protective film adhering to the stainless steel panels should be left on until installation is completed.
BUT THIS MUST BE REMOVED BEFORE COMMISSIONING OR OPERATING THE APPLIANCE.
Check the appliance Data Plate (located on the rear of the flue upstand/splashback panel), to ensure that
the appliance is suitable for the gas supply available.
Ensure that the floor upon which the appliance is to stand is level and capable of adequately supporting
the weight of the appliance. TO COMPENSATE FOR SOME UNEVENNESS OF THE FLOOR, THE
APPLIANCE FEET ARE ADJUSTABLE.
THE FLOOR MUST BE FIRE-PROOF. If it is not, or if any adjacent wall or surface is made of a
combustible material, then the installer MUST ensure that the requirements of the LOCAL FIRE
REGULATIONS are observed.
Positioning
Place the appliance in position allowing a minimum gap of 100mm (4”) at the rear and at least 150mm
(6”) between the sides of the appliance and any adjacent wall. If the appliance is being suited then please
refer to the separate instructions. The minimum distance between the hotplate and any overshelf or
ceiling constructed of a combustible material must be 1525mm (60”).
Adequate ventilation is essential for safe operation of a gas appliance. A supply of fresh air is necessary
for the correct combustion of the gas and there must be a means of exhausting the heat and the
products of combustion from the kitchen. It is recommended that the appliance be sited below a
ventilating hood, one preferably connected to an extractor system incorporating a grease filter.
Appliances are to be installed with sufficient ventilation to prevent the occurrence of unacceptable
concentrations of substances harmful to health in the room in which they are installed.

Installation (cont.)
Important Note
The appliance MUST NOT be connected DIRECTLY to a flue or ventilating system, although the flue
products of two or more appliances may be directed into a common outlet when building a suite of
appliances (see separate instructions for suiting appliances).
Ensure that the appliance is level in two places - front to rear and side to side. To check the level it is
recommended that a spirit level be placed on a shelf in the open oven - NOT on top of the hotplate!
Level can be achieved by adjusting any or all of the screw in feet in each corner of the base. Turn anticlockwise to lower and clockwise to raise the corner.
Gas Connection
Natural Gas: The size of the supply pipe should be no smaller than ½” BSP and an easily accessible
stopcock must be fitted in the gas line adjacent to the appliance. The gas governor provided with the
appliance MUST be fitted in the supply line BETWEEN the stopcock and the appliance.
Armoured flexible pipe of a GAS COUNCIL APPROVED PATTERN must be used to facilitate servicing.
NOTE:
Due to the pressure loss through the snap connection fitting on flexible hoses you must fit a 1”
flexible hose to the following models:
MV1RGP60-OT, MV1RGP90-OT, MV1RGP120-OT, MV1RGP60-OT-PB,
MV1RGP90-OT-PB, MV1RGP120-OT-PB,
Ensure that all the pipes to the appliance are clean and free from swarf etc, BEFORE making the final
connection.
Propane Gas: Follow the same procedure as that for Natural Gas EXCEPT that the Gas Governor MUST
NOT be fitted - the Gas Supply Tank or Cylinders are already fitted with a Gas Regulator.

Installation (cont.)
Leak Test
Clean off any protective film from the stainless steel panels.
AT THIS STAGE, LEAK TEST THE WHOLE SYSTEM. THE GAS SAFETY REGULATIONS require that ALL
connections in the gas supply line between the Gas Meter and the appliance is tested for gas leaks.
THIS MUST BE DONE BEFORE COMMENCING TO COMMISSION THE APPLIANCE.
Checking and Commissioning
ALTHOUGH EVERY APPLIANCE IS TESTED AND SET BEFORE IT LEAVES THE FACTORY, IT IS
IMPORTANT THAT THE INSTALLER RE-CHECKS CERTAIN FUNCTIONS BEFORE LEAVING THE SITE.
CHECK THE GAS PRESSURE AT THE APPLIANCE THUS: The pressure test point is located on the manifold rail behind the front control panel, which is secured
by two M5 screws.
Connect a manometer (U tube) to the test point. Turn on the gas supply and light the Oven (or for
Ranges light 4 outer hotplate burners plus the oven, for 1200 8 burner range light up 4 outer burners
plus both ovens). Check that the pressure reading agrees with that stated on the data Plate.
SHOULD ADJUSTMENT BE NECESSARY, PROCEED AS FOLLOWS: FOR PROPANE GAS, REFER TO SUPPLIER.
On the gas governor: Remove the cap in order to gain access to the pressure adjusting screw.
Turn the pressure adjusting screw clockwise to increase the pressure or anti-clockwise to decrease it.
When the pressure reading is correct, refit the cap to the governor.
Turn the gas supply to the unit OFF at the stopcock and disconnect the manometer (U tube). Ensure that
the pressure test point screw is refitted.
Turn the gas supply to the appliance on at the stopcock and leak test the pressure test point.
Burner Aeration
The aeration of all the burners is fixed and does not need adjusting.
The parts protected by the manufacturer or his agent are not to be adjusted by the installer.
The appliance must be equipotentially earth bonded.

The temperatures will vary from the above figures by as much as 20°C hotter at the top of the oven and
30°C cooler towards the bottom of the oven. But remember these are temperatures in an empty oven.
To cook identical products on two shelves, select two shelf positions with a sufficient gap between them
to allow air movement in the oven. For example, cooking small cakes or pastry use shelf positions 2 & 5,
counting from the top of the oven. Allow the food to cook for just over half the normal time and then
change the position of the shelves.
As an alternative leave the food on the upper shelf until it is cooked, then move the food from the lower
shelf to the upper shelf, or leave on the lower shelf until cooked.

Users Instructions (cont.)
Cooking identical foods on three different shelves is seldom satisfactory and is not recommended, but
the “cool zone” at the oven bottom can be sometimes used for slow casseroles, whilst general and
specialised cooking is carried out on the two shelves.
The following cooking chart is for guidance on thermostat settings. Make a note of the settings you find
most acceptable.

Cleaning the Equipment (cont.)
Open Top Hotplates
Wipe the open top pan support grids clean of grease and spillage’s regularly - even during cooking
sessions - a crust of burned on carbon, coating the pan supports is unsightly, is a health hazard and will
impair cooking efficiency.
Daily: Soak the pan support grids in a mild solution of a grease dissolving agent or detergent - DO NOT
USE A CAUSTIC CLEANING AGENT - and wash. Accumulated deposits may be removed by soaking and
then carefully scraping or a fine cleaning paste could be tried.
SOME PAN SUPPORT GRIDS ARE VITREOUS ENAMELLED - DO NOT USE CAUSTIC CLEANERS AT ALL.
WIPE OVER WITH A LIGHT COATING OF COOKING OIL AFTER CLEANING AND DRYING.
The burner caps and burner rings may be removed from the open hotplate burners for cleaning. Soak
and wash in a mild detergent solution, rinse and dry thoroughly before replacing. DO NOT allow water
or cleaning agents to enter the burner venturi. DO NOT use caustic cleaners on burner parts.
DO NOT scrape or poke the burner port ring, soak and then carefully BRUSH clean any stubborn
accumulations of dirt.
REPLACE THE BURNER COMPONENTS CAREFULLY IN THEIR CORRECT POSITIONS.
Remove the pan support castings The burner drip shields can be cleaned by washing these with a mild
detergent, rinse and then dry. This MUST be carried out on a daily basis and immediately following a
spillage.
The Oven
The oven shelves and the oven shelf supports can be removed for cleaning. Withdraw the shelves in the
normal way, rub them free of grease using an absorbent paper pad and wash in a hot detergent solution.
Rinse and dry before replacing.
The shelf supports are removed by lifting them free from their locating brackets and withdrawing them
from the oven interior. They, too, can be washed in a hot detergent solution and rinsed and dried before
replacing.
Clean the oven interior and the oven door-lining daily, using a hot mild detergent solution. This is
especially necessary if a spillage has occurred, meat has been roasted or fruit pies baked. Rinse with
clean water. Stubborn accumulations can be gently scraped off after soaking.
