Be sure that the valve on the gas cylinder is closed and the burners of the appliance are extinguished.

Unscrew the nut by which the gas regulator is connected to the gas cylinder valve. (Note that most connections are with left-

handed threads. They open in clockwise direction).

Before connecting the (new) gas cylinder, first check if the rubber seals on the cylinder valve or on the regulator-connecting

nut are fitted properly and able to fulfil its function and are not damaged or worn. In that last case do not use it or replace the

seals.

After connecting the regulator firmly, open the cylinder valve and check with soapy water if the connection is leak tight. If

bubbles appear, the connection leaks. Do not use the appliance unless the system is sound. Make sure that the gas cylinder

is securely fixed and never can turn over. Always close the gas valve of empty cylinders while due to temperature raise again

gas can escape.

4.5 What to do by gas leakage

When a gas leak is detected, immediately close the gas supply. Keep open flames away. Do not use the appliance anymore. Contact an

authorised gas technician, gas installer or gas service agent to determine if the gas leakage can be repaired. Never try to do gas repairs

by yourself. Do not use the appliance anymore until the problem is solved.

5. Operation

5.1 How to mount the appliance in a parasol

Open the parasol (with the mounting brackets already in place, see chapter 3)

Take the appliance in both hands and move the opening around the pole of the parasol (fig. 6)

Turn the appliance in such a way that the mounting screw and the bracket with the threaded part are close to each other. (fig.

7a)

Slide the burner ring in the 2 brackets (fig. 7b, 8a) and slide the mounting nut on the bracket with the treaded part (fig. 7c, 8b).

Screw the mounting nut as far as possible on the bracket. When the nut is fully mounted, the thread is visible at the end of the

nut (fig. 7d, 8c)

Connect the gas regulator to the gas cylinder (or connect the gas hose to the gas line).

5.2 How to mount the appliance in a pagoda tent or other structure

Place the hooks on the frame or structure (as showed in fig 2e, 2f and 3c and see also chapter 3.)

Attach the chains of the appliance to the hooks.

Mount the gas hose in a safe way as indicated in chapter 3

Connect the gas regulator to the gas cylinder (or connect the gas hose to the gas line)

5.3 How to operate the appliance

A) Ignition.

Open the valve on the gas cylinder (fig. 9) or open the gas valve in the gas line (fig. 10). Make sure that the appliance ignites

on full pressure in case of a high-low appliance. Cold ignition on low setting is very difficult and sometimes impossible.

Take a (BBQ) lighter or long match and keep the flame under the burner gauze directly on the ceramic burner stone. (Fig. 11,

number 1). Use the ignition hole in the burner gauze situated by the upper burner stone.

Push with your thumb the knob on the safety device. The burner will ignite after a few seconds. (Fig. 11, number 2).

Note: When the appliance is ignited for the first time (or after storage for a period), ignition of the first burner will take some

time because it takes a while before the air in the gas line is replaced by gas. This can be up till 30-60 seconds. The other 3

burners will ignite quickly. Check if both burner stones are ignited.

After ignition, keep the knob in pressed position for about 20 seconds. (Fig. 12).

Release the knob. The burner will stay alight. In case the burner extinguishes directly after releasing the knob, wait for 10

seconds and repeat the ignition procedure. After ignition, a high-low appliance (PH-8 for I3P 50-150 mbar with an adjustable

regulator) can be set on low setting after a preheating time of 3 minutes. This can be done by turning the knob on the

regulator from 10 to a lower number.

Note: All 4 burners must be ignited separately. It is the decision of the user how many burners are ignited, depending the heat demand

at that moment.

Note: A new appliance, used for the first time, sometimes gives a little bit of smoke and smell. Although the burners are cleaned after

production a little bit of remaining protection liquid is causing this. This only happens the first time and stops after a few minutes, when

the appliance is on temperature.

B) How to check correct operation of the burners

Directly after ignition the burner flames are blue (difficult to see during daylight, better to see in the evening or at night). After 1 to 3

minutes, the ceramic burner stone starts glowing and becomes orange. The orange colour shall be evenly spread over the burner

surface. The burner gauze is glowing dark red. The flames will not leave the confines of the burners. The burners shall not make a lot of

noice.

C) Extinguishing.

To extinguish the burners close the gas cylinder valve (fig. 13) or the valve in the gas line (fig. 14). After a few seconds, the flames will

disappear.

Note: It is not possible to extinguish the burners independently of each other. Closing the gas supply is the only way. Then reignite after

3 minutes the amount of burners required at that moment.

Note: After the burners are extinguished, always wait for at least 3 minutes before igniting the burners again. This time is needed by the

safety device to cool down and shut-off the safety valve before re-ignition can be done safely. Not following this rule can create the

unsafe situation that during ignition the flames leave the confines of the burner. (This is a general safety rule world wide for all gas

appliances with thermocouple safety devices).

Cleaning, maintenance and servicing

In case the painted surfaces are dirty, they can be cleaned with a moisture cloth and some mild soap. Dust can be removed with a soft

brush. Stainless steel parts can be cleaned with normal domestic stainless steel cleaner. The stainless steel parts of the burners will

discolour a bit by the heat during use. This cannot be removed but has no influence on lifetime or operation of the appliance. The

appliance does not need special daily maintenance and service. We advice at least once a year a maintenance and service check by a

competent gas servicing agent.
