3. INSTALLATION
The fryer must be installed either by the manufacturer’s qualified and experienced
technicians, by an authorized installer or by the gas supplying company.
Before installing and turning on the fryer, read the instructions in this manual thoroughly and
in particular the safety standards.
WARNING: All parts that are protected by the manufacturer may not be manipulated
neither by the installer nor the user.
This fryer is designed for professional use and must be used by trained staff. Before
connecting the unit, please verify:
a. that allremovable parts are in the correct position. If some part moved during
transport, first readjust it.
b. that the fryer is leveled correctly. If necessary, adjust leg height.
3.1. PLACE OF INSTALLATION
Install this fryer in a location where adequate combustion and ventilation air are available.
Follow the current local norms. The adequate air flow input to the fryer system must be 2
m3 per Kcal/hour installed.
Install this fryer individually or together with other NT Gas devices.
A minimum of 150 mm should be maintained between the fryer and any combustible
material.
WARNING: If the fryer is not installed in a draughty place, unacceptable
concentrations of substances harmful to health can occur or even cause death.
3.2. ELIMINATION OF COMBUSTION RESIDUES
Type A3: Combustion residues of this one fry pot fryer are eliminated directly through the
rectangular outlet located on top of the fryer.
The fryer should not necessarily be connected to an exhaust duct outward. Install the fryer
preferably under a ventilation hood that conducts combustion products outside the building.
DO NOT obstruct the outlet of combustion residues and flow of ventilation air.
This device needs an AIRFLOW of 395m3/h for a correct combustion and elimination
of combustion residues.

7/ 16
3.3. GAS CONNECTION
Before connecting the fryer, consult your gas supplier and check whether your gas network
supplies the necessary pressure and flow in order to ensure a proper operation of the fryer.
This device is equipped with a gas connection threaded ½” in accordance with norm EN
10226. A seal can be placed on the end if necessary.
The plate next to the gas connection indicates the gas type for which this fryer is
configured.
Check the gas pressure at the inlet. Since pressure loss by the gas network is possible, it
is advisable to install a pressure regulator or stabilizer to prevent the inlet pressure to the
fryer to exceed the pressure indicated on the plate (see Chapter 2 – Technical Information).
This gas appliance must be installed by authorized personnel. Both rigid and flexible non-
metallic pipes may be used according to norm EN 53539 or flexible metallic pipes according
to norm EN 14800. Pipes should never exceed the length of 1,5 mt. If rigid pipes are used,
then a stopcock must be installed as close as possible to the fryer’s connection.
Connect the fryer to the gas network according to the current regulations. Once the
installation is completed, check with soapy water or a manometer that the pipes are leak
proof.
Never use a flame to verify if there are leaks.
In caseyou wish to connect the fryer to a gas bottle, make sure the bottle is always in
vertical position and it complies with following characteristics:

BUTANE
12,5 KG
PROPANE

NOTE: install a gas pressure regulator on gas bottles in order to ensure an adequate
pressure.
3.4. START-UP
Nominal thermal power control
Thermal power of the device must be verified by an authorized technician according to the
indications described in this manual after every maintenance operation, in case of new
installation or if the device is converted to a type of gas different than that for which it was
configured originally.
Nominal thermal powers for each model are indicated on the chart of Chapter 2. - Technical
Information).

TECHNICAL INSTRUCTIONS FOR INSTALLATION, USE AND MAINTENANCE GB

Inletpressure control
Check whether the device is configured for the desired type of gas. Revise the information
mentioned on the plate of the device as well as charts of Chapter 2 of this manual. In case
the gas type is different, adapt the fryer to the new gas type as shown in chapter 2.3.
Use a U-shaped manometer with a resolution of minimum 0,1 mbar to measure the gas
pressure of the fryer at the gas inlet. If the gas pressure is not between the values
indicated on chart 2.3, do not set the unit into operation and inform your gas supplier
hereof.
Operation control
Start up the fryer following these instructions:
a. Verify that the gas circuit is gastight.
b. Verify the working of the drain valve.
c. Verify the ignition and quality of the flame.
4. TECHNICAL MAINTENANCE
Maintenance must be performed by a qualified and authorized technician or by the gas
supplying company.
It is recommended to carry out semi-annual general controls of the fryer (and draw up a
maintenance contract). Verify:
a. that the gas circuit is gastight. Replace seals if necessary.
b. the working of the ignition system.
c. the working of the regulation thermostat and the safety thermostat.
d. the expiry date of the flexible pipe. Replace it if necessary.
5. REPLACEMENT OF COMPONENTS
Only an authorized installer or a qualified technician of the gas company may replace spare
parts.
A general review is recommended to be done at least two times a year.
The front panel gives access to the controls of the fryer.
Sparkcontrol and solenoid valve
To replace the spark control and solenoid valve, loosen all connexions and unscrew all nuts
of the solenoid valve.
Insert the correct seal on the valve and tighten all other connections so as to avoid gas
escapes. Proceed as follows:
