relevant National / Local codes covering gas and fire safety.

Australia:

AS 5601/AG 601 (to be AS 5601)- Gas Installations

New Zealand:

NZS 5261 - Gas Installation.

United Kingdom:

Gas Safety (Installation and Use) Regulations 1998

BS 6173-Installation of Catering Appliances.

BS 5440-1&2 Installation Flueing & Ventilation.

• Check that the available gas supply is correct to that shown on the rating plate located on the right hand panel.

Location

1. Installation must allow for a sufficient flow of fresh air for the combustion air supply.

2. Installation must include adequate ventilation means, to prevent dangerous build-up of combustion products.

3. Any gas burning appliance requires adequate clearance and ventilation for optimum and trouble-free operation.

The minimum installation clearances shown below are to be adhered to.

4. Position the appliance in its approximate working position.

5. All air for burner combustion is supplied from underneath the unit. The legs must always be fitted and no

obstructions placed on the underside or around the base of the unit, as obstructions will cause incorrect

operation and / or failure of the appliance.

6. Components having adjustments protected by manufacturer are only allowed to be adjusted by an authorized

Installation

Clearances

NOTE: Only non-combustible materials can be used in close proximity to this appliance.

Assembly

NOTE:

•This appliance is assembled before delivery except castors.

•This appliance is fitted with adjustable castors to enable the appliance to be positioned securely

and level. This should be carried out on completion of the gas connection. Refer to the ‘Gas

Connection’ section.

•IM will be stated that the appliance shall be installed in such a way that side body surfaces are

not accessible in the installed position.

Gas Connection

NOTE: ALL GAS FITTING MUST ONLY BE CARRIED OUT BY A QUALIFIED PERSON.

A 3/4" male BSP line for the gas connection is located near the lower right rear corner of the fryer. The

serial plate (located inside the front door of the fryer) indicates the type of gas the unit is equipped to

burn (natural gas or propane). The fryer should be connected ONLY to the type of gas for which it is

equipped.

For orifice sizes and pressure regulator settings, see the chart on page 4. If the fryer is being installed at

over 2,000 feet altitude and that information was not specified when ordered, contact the appropriate

authorized Thor Service Representative or the Thor Service Department. Failure to install with proper

orifice sizing will result in poor performance and may void the warranty.

If applicable, the vent line from the gas appliance pressure regulator shall be installed to the outdoors in

accordance with local codes or, in the absence of local codes, with the Australia: AS 5601/AG 601 (to be

AS 5601) - Gas Installations or New Zealand: NZS 5261 - Gas Installation.

An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of gas

necessary for satisfactory performance. A combination gas valve and pressure regulator, which is provided

with each unit, is set to maintain a 1.0kPa manifold pressure for natural gas or 2.75kPa manifold pressure

for propane gas. Fluctuations of more than 25% on natural gas or 10% on propane gas will create

problems and affect burner operating characteristics.

Purge the supply line to clean out dust, dirt, or other foreign matter before connecting the line to the unit.

It is recommended that an individual manual shutoff valve be installed in the gas supply line to the unit.

Use pipe joint compound that is suitable for use with both natural and LP gas on all threaded connections.

ALL PIPE JOINTS AND CONNECTIONS MUST BE TESTED THOROUGHLY FOR GAS LEAKS. USE ONLY SOAPY

WATER FOR TESTING ON ALL GASES. NEVER USE AN OPEN FLAME TO CHECK FOR GAS LEAKS. ALL

CONNECTIONS MUST BE CHECKED FOR LEAKS AFTER THE UNIT HAS BEEN PUT INTO OPERATION. TEST

PRESSURE SHOULD NOT EXCEED 3.45kPa

CAUTION

THIS APPLIANCE AND ITS INDIVIDUAL COMBINATION GAS VALVE MUST BE DISCONNECTED FROM THE

GAS SUPPLY PIPING SYSTEM DURING ANY PRESSURE TESTING OF THAT SYSTEM AT TEST PRESSURES

IN EXCESS OF 14”WC (1/2 PSIG or 3.45 kPa).

If the incoming gas pressure is in excess of 14"WC (1/2PSI, 3.45 kPa), a proper step-down regulator

will be required.

Connect the gas supply directly to the 3/4" male BSP connector located near the lower left rear corner of the fryer.

When tightening the supply pipe, be sure to hold the mating connector extending from the unit securely with a

wrench. This will prevent any damage or distortion to the internal piping and controls of the unit.

After connecting the gas supply, check again that the fryer is level. Use a long spirit level four ways; across the front

and rear of the fryer pot, and along each edge.

Filling the fryer pot

1. Close drain valve completely before filling the fryer pot.

2. When the fryer is new, fill the fryer pot with water and clean thoroughly (see “Weekly Cleaning” on

page 14) in order to remove protective coatings and any foreign matter.

3. The recommended solid shortening capacity for the fryer pot (35, 55 or 75lbs) is described on the serial

plate (which is located inside the front door).

4. Remove the basket support frame when filling the fryer pot with solid shortening.

5. When solid shortening is used, be careful not to bend, break, or twist the thin capillary wires of the

sensing elements located in the fryer pot.

6. Pack solid shortening into the zone below the tubes, all spaces between the tubes, and at least an inch

above the top of the tubes before lighting the fryer. If any air spaces are left around the heat tube

surfaces when the heat is turned on, the tube surfaces will become red hot, burn the solid shortening,

weaken the fryer pot, and could result in a fire.

CAUTION

NEVER ATTEMPT TO MELT A SOLID BLOCK OF SHORTENING ON TOP OF THE HEAT TUBES. NEVER START THE BURNERS

WHEN THE FRYPOT IS EMPTY.

7. To prevent burning or scorching the solid shortening, keep the thermostat set at the lowest

temperature until all the solid shortening between and above the tubes has been melted. Additional

solid shortening can then be added until the desired frying depth has been reached.

8. Replace the basket support frame over the fryer pot heat tubes.

Automatic Pilot Valve

The Automatic Pilot Valve provides an automatic safety shutoff for the fryer when the pilot flame is

extinguished. When the pilot flame is burning, the valve is held open electromagnetically by the electrical

current from a thermopile in the pilot flame. When the pilot flame goes out, generation of current ceases and

the valve closes automatically.
