The gas hose shall always be connected to the heater with the help of hose clips. Not using hose clips

at both ends of the gas hose is very dangerous. Make sure that the gas hose never is heated above 40

degrees Celsius.

Changing gas cylinders

In case gas cylinders are used, changing or connecting gas cylinders must be done preferably outside,

or in a well-ventilated area, in a flame-free environment and away from other people.

Check if there are no other operating heaters, other gas heaters, burning candles or people smoking

cigarettes in the area.

Be sure that the valve on the gas cylinder is closed, electricity to the heaters is disconnected and

the burner of the heater is 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. If the last case is true, do not use it and replace the seals first.

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 heater unless the

system is sound.

Soundness check

Before using a new built gas system, first make sure that the installer made a careful and extensive

check for gas leakage. After executing a pressure drop test to determine that there are not large leaks,

check every connection with soapy water or gas detection liquid with all gas valves open and with

maximum gas pressure. Pay special attention to the hose connections. Maintain maximum air ventilation

during the test. Repeat this check at least every year. This soundness check shall be done by a

competent installer only.

Gas leakage

When a gas leak is detected, immediately close the gas

supply and disconnect electricity. Keep flames away.

Do not use the heater 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 heater

anymore until the problem is solved.

Operation

New heaters

New heaters need a cleaning period before they are ready for operation. Turn the ventilation to maximum

position or place the heaters outside in the open air. Fire the heaters for at least two hours on full capacity

to burn-off oily and greasy remnants of the production. Make sure that after two hours all smoke and

smell is disappeared. The smoke and smell can be unhealthy, so keep animals and human beings away

till the heaters and the environment air is clean.

Ignition of the heater

Warning: after a manual operated heater is extinguished (intentionally or unintentionally) wait always for

3 minutes before (re)ignition. This is a worldwide safety rule and intended to ventilate unburned gases

away and to leave enough time for the thermocouple device to close.

Ignition shall always be done in high fire. So, the gas pressure shall be adjusted at maximum pressure,

solenoid valves shall be in open position, thermostats shall be on maximum setting. In case the heaters

are operated by a barn computer, this computer shall be programmed in such a way that during ignition

the heaters are operated for at least 30 seconds in high fire.
