General Hints

² The unit may be operated only by those persons who have been instructed regarding the unit’s operation and the handling of liquid gas.

² When using the unit make sure always to observe the guiding principles of the countries and states concerned.

² The unit may only be operated in rooms when

– the air rate fed to the unit is sufficient for com-

bustion and

– the rooms are well ventilated and deventilated

and

– the percentage of the substances which are

injurious to health in the breathed in air has

no inadmissible concentration.

A good and natural ventilation and deventilation is given if e.g. the room volume in m³ corresponds to at least 30 times the nominal heat load in kW of all the units being operated in the room, and if a natural air exchange through doors and windows is ensured, or if there are permanently open ventilation possibilities for ingoing and outgoing air near the ceiling and the floor, of which the size in m² corresponds to at least 0.003 times the nominal heat load in kW of all the units being operated in the room.

² A uniform unit connection pressure of 1.5 bar (1500 mbar) of the category I 3B/P is necessary for all the countries of the European Community.

The connection pressure may not fall below or

exceed the required value.

² Make sure to use exclusively components, such as gas hose, pressure controller and hose security devices (protection against breakage) or safety devices against gas leakage, that have been tested and are suitable for the intended purpose. The pressure controllers must have a firmly regulated initial pressure of 1500 mbar and are to be equipped with a security device against hose breakage.

² Hose pipes are to be protected generally against chemical, thermal and mechanical damage.

² The persons charged with the operation of the unit have to check it prior to starting work to make sure that there are no visible defects. If there are defects which affect the unit’s operational reliability, its operation is to be stopped!

² The unit may be only maintained by trained persons and only original spare parts may be used.

² If the unit has been switched off by the temperature limiter due to overheating, the reason for the fault has to be detected and eliminated.

Starting

Make sure to charge a person with the operation of the unit and with the supervision of the reservoirs and of the bottle stock who has been instructed sufficiently regarding the handlings concerned.

Make sure to draw the operators‘ attention to possible dangers during the handling of liquid gas.

G

A constant unit connection pressure of 1.5 bar

(1500 mbar) must be ensured, also during continuous operation.

Heating Operation

Put the operating switch into position

"O" (= Off) and plug the mains into an appropriate mains socket with fault current safety switch (230V/1~ 50 Hz)

Put the operating switch into "I" position

(= heating operation)

The supply air fan starts.

Connect pressure controller to the gas bottle(s).

G

Attention – left-handed thread!

Press down pin of thermoelectric gas valve (safety pilot).

Open bottle valve(s).

When gas is taken out of several gas bottles simultaneously, all the valves have to be opened.

Press release button of the hose security device (protection against breakage) valve(s). after having opened

This has also to be done after each replacement of bottles. the

After approx. 2 or 3 sec. the piezo igniter is to be actuated (possibly several times) with the pin still held down, until a formation of flames has occured.

After the formation of flames still hold down the pin for approx. 10 seconds, until the thermoelectric flame monitoring has started.

Do not release the pin before this.

If the flame is extinguished after the pin has been released, repeat the ignition procedure after having waited for approx. 1 minute. Then keep the pin pressed down a little longer.

After the installation and connection of the units all the gas bearing connections have to be checked with soap solution, leakage detecting spray etc. to make sure that they are tight.

Do not use open flames!

Important Installation Hint

When installing or removing the gas hose make sure to exert a counterpressure on the gas connection nipple of the unit using an open-end spanner SW 19 and observing the left-handed thread.

1.

2.

1) Unscrew gas hose

Turn union nut clockwise

2) Fasten gas hose

Turn union nut anti-clockwise

This procedure also refers to all further gas components, such as pressure controller, hose security device (protection against breakage), etc.

Setting/Regulating the Heating Capacity

Set desired heating capacity by means of the continuously adjustable “power regulation”.

The setting can also be continuously adjusted when the unit is operating.

Ventilation

- remove protective cap (1)

- press key (2)

- refit protective cap (1)

Put operating switch into “0” position (= off) and unplug mains plug from the mains socket.

“RESETTING” is not possible before the sensor has cooled down below approx. 90 °C.

You will find a detailed chart for the fault elimination in chapter “Action in the case of faults”.

Important Hints

Assembly of Multi-bottle Set

To avoid intensive icing of the gas bottle during a longer operation of the unit, we recommend that you use a bottle battery consisting of at least 3 bottles. All bottle valves must be open to ensure regular gas supply! hose-break protection pressure controller high pressure hose 0.4 m

T-connection gas hose to unit

Important!

Make sure to place gas reservoir only laterally behind the unit! Never heat up or defrost gas reservoir through the unit’s hot air current ( danger of explosion!

).

Never use gas reservoir in a lying position when the unit is operating (gas leakage in the liquid phase).

The safety temperature limiter (STB) interrupts gas supply in the case of overheating and the unit is locked on the electric side. Any unit function is switched off.

When the safety temperature limiter has released, the reason for the fault is to be detected and to be eliminated first. Unlocking is carried out when the protective cap has been unscrewed by pressing the key “STB-

RESET“.

Maintenance

Depending on the operation conditions the units are to be tested by an expert when necessary, but at least regularly every two years, to ensure their safe operation.

The test result is to be recorded in a test certificate which is to be safely kept until the next test so that it can be presented to the authorized persons for control purposes at any time.

The persons charged with the operation of the units have to check the units before starting work to detect obvious defects on the operating and safety elements and to make sure that the safety devices have not been removed.

If any faults are stated the supervisor is to be informed.

If the faults affect the unit’s operational reliability, operation is to be stopped! l Regular maintenance and care, at least after each heating period is the basic condition for a long service life and a faultless operation of the unit. l Make sure to keep the unit free from dust and other deposits and to clean it only with a dry or humid cloth

(do not use water jet). l Do not use sharp or solvent-containing cleaning agents. l Check the suction opening for combustion air as well as the injector fitted behind it and the gas nozzle regularly to make sure that they are not dirty. l Clean gas burner and gas nozzle regularly. l Clean baffle plate regularly. l Check suction and blowing out lattice regularly to see whether it is dirty and clean it, when necessary.

G When the unit is being maintained, set or repaired, the gas supply has to be cut off and the mains plug has to be unplugged from the mains socket!

G

Setting and maintenance work is to be carried out only by authorized specialists!

G

Clean gas supply line thoroughly before starting the unit for the first time!
