3.5 First installation of the appliance in a pagoda tent or other structure (Models with suffix C)

To carry out the first installation 2 persons are needed. It will take about 10 minutes.

Check if the structure or construction of the pagoda tent is strong enough for mounting the appliance. Check also the safety

distances to combustible materials.

Make sure that there is enough ventilation to ventilate the combustion gases away. This is to avoid condensation of water

from the combustion gases and to limit the heat accumulation.

Wrap the cable strap with the hook around the central frame of the pagoda tent or other available construction (see fig. 2e and

2f)

Cut the chains into 8 pieces with a length required in the specific situation and attach the chains to the appliance with the S-

shaped hooks. Attach the other end of the chains to the hooks mounted on the structure (see fig. 3c).

Make sure that the chains are mounted in V-shape as showed in fig. 3c. The burners are now placed in the free space

between the frames. Never place the burners in such a position that the combustion gases heat the frame. Check if the ring is

in horizontal position and adjust if necessary. Close the S-shaped hooks with a pair of pincers.

Attach the gas hose to the frame as showed in fig 3c. Make sure that the gas hose is always in the cold zone between two

burners and never is heated by the combustion gases or radiation heat.

Connect the appliance to the gas supply and check all connections for gas leaks with soapy water for soundness. (See next

chapters).

Ignite the burners and check for proper operation. (See next chapters).

4. Gas supply information

4.1 Gas supply

In case a gas line supplies the gas to the appliance, make sure that an authorised company in your country, in accordance with the local

rules and requirements, makes the system. Always mount a (easy to be reached) gas tap at the end of the gas line. This gas tap is

needed to close the gas supply to the burners to extinguish the flames. In addition, it makes it possible to remove the appliance after

use. For data needed to calculate the dimensions of the gas line, see the technical table.

The gas can also be supplied from butane or propane gas cylinders. The minimum size is a 5 kg cylinder for the PH-4 and 11 kg for the

PH-8. Before buying a cylinder make sure that the connections of the gas regulator and the gas valve of the cylinder are of the same

type. Store the gas cylinder always above the ground in a well-ventilated place. In case the gas cylinder is placed in a cylinder housing,

or cover, make sure that there is enough ventilation as requested by the applicable regulations or standards. Never obstruct these

ventilation holes. The gas cylinder has to be placed under the parasol, directly against the pole of the parasol. In case of pagoda tents,

place the gas cylinder outside the pagoda tent or on sufficient distance from the burners (at least 4 meters) on a place where the

cylinder is protected against radiation heat from the burners. Fasten the gas cylinder to a pole or other structure to make sure that the

cylinder never can turn over. Make sure that the gas cylinder valve can easily be reached to close the gas supply in an emergency

situation. Protect the gas regulator for influences like rain and snow. These can influence proper operation of this device.

Always make sure that the gas pressure and the kind of gas supplied is in accordance with the information on the data plate of the

appliance.

4.2 Gas hose

Make sure that the gas hose never is heated above 40 degrees Celsius. The gas hose must be inspected frequently and must be

changed within the prescribed intervals. Our advice is to check the hose every time the gas cylinder is changed, but at least once a

month. Avoid twisting or stress of the gas hose. Twisting or stress will shorten the live time of the gas hose. During inspection, check the

hose for damage, splitting, ageing and cracking. Pay special attention to the connections. If a defect is seen directly change the gas

hose by a new one of the same type. Some countries have regulations that gas hoses must be replaced every 2 or 3 years. Please

check with your gas supplier. We advice to change the hose every 3 years in case there are no regulations in your country. Always use

official gas hoses. Replace a gas hose always by a type of the same length, internal diameter and equivalent quality. For your own

safety: never use air hoses or water hoses, these are very dangerous for gas transportation! We advice to mount a special safety device

(hose rupture protection device) on the gas cylinder that closes the gas flow as soon as somewhere a gas leak occurs.

As an option (not standard), the gas hose can be delivered with a metal protection around the gas hose. In that case, in addition to the

instructions above we advice a leak test with water every 3 months because inspection is more difficult by the metal protection. Place

the appliance on the ground and connect it to the gas cylinder. Open the gas valve. Submerge the gas hose as far as possible in a

bucket with water and check for bubbles (indicating a gas leak). Check the last part of the gas hose near the gas cylinder and the

appliance with soapy water. Also, check the metal protection for damage. Loose wire ends of the metal protection can hurt people.

Replace the hose in case of leakage or damage.

In some cases the gas hose and gas regulator will not be delivered with the appliance. Contact your local gas supplier to buy these

items. Also he can advice you about the local requirements. Always use locally or nationally approved gas hoses and regulators. Before

buying a gas regulator check the data plate on the appliance to determine which gas, outlet pressure setting and gas consumption of

the regulator is required. The regulator shall be of a non-adjustable type, (except for model PH-8, propane 50-150 mbar).

The minimum length of the hose required under normal installation height in a parasol of 200 cm is 220 cm and shall have an internal

diameter of 8 mm. In case the appliance is mounted in a higher position (or in a pagoda tent), a longer length is required depending your

particular situation. Avoid the unsafe situation where the hose is too long and reached the ground. In that case people can stumble over

the hose or the hose can be easily damaged by other stuff placed on it. Be sure that the gas hose is suitable for LPG gases (or natural

gases, depending the gas selection). We advice to buy a hose already connected to the regulator. Attach the hose to the gas inlet nipple

(8 mm) of the appliance and secure it with a clamp. Before using the appliance, check with soapy water the connection on gas leaks. No

bubbles are allowed to appear.

4.3 Quick connection (optional, not standard)

As an option, a quick connection device is available (only with rubber hoses). The quick connection device makes it possible to

disconnect the gas hose from the appliance. It makes handling and storage easier. When disconnected carefully protect the quick

connection device from dust and dirt. Before disconnecting always close the gas cylinder valve and wait until the burners are

extinguished. Check the quick connection device with the same frequency as the gas hose for leakage and proper function. Check

before each use if the male nipple does not have burrs.

4.4 Changing gas cylinders

Changing or connecting gas cylinders must be done outside, or in an amply ventilated area, in a flame-free environment and away from

other people.

Check if there are no other operating patio heaters, other gas appliances, burning candles or people smoking cigarettes in the

area.
