The most common way to install a gas line is in the centre of the barn (at least 2 meter high) with every 3 to 5
meter a "T" or "cross" connection for gas supply to the heaters. Always mount a (easy reachable) gas tap at the
beginning of the gas hose to the heaters. 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 heaters after use or to service the heaters
safely. The gas inlet at the heater side is normally an 8 mm hose nipple (optional a smooth hose nipple or a
G1/8" right handed thread. Other connections are possible after consultation). Always use approved gas sealant
to close the gas connections.
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 if there are not large leaks, check every
connection with soapy water or gas detection liquid with all gas valves in open position 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.
Burner operation
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.
The gas heater burns properly when the colour of the ceramic stone and burner gauze is orange/red. In case
the flame burns outside the burner gauze, check and clean the heater first and clean the filter. Also bad quality
gas or wrong gas pressure can cause this. Consult a gas installer in this case. The installation of the heater in
a draughty area may result in a loss of efficiency. If possible install in a draft free area or turn the face of the
heater away from the draft.
Ignition procedure (always ignite on maximum gas pressure)
Open the gas valve on the gas cylinder / gas tank / gas pipe and turn the gas pressure regulator at
maximum capacity. Turn the thermostat on maximum temperature.
Check all gas connections, hoses and gas regulators for leaks with soapy water.
Ignite a safety match or BBQ gas lighter and keep the flame at the burner gauze (2).
Press the button of the safety device (15). The gas heater shall ignite now within a few seconds.
Continue to press the button of the safety device for approx 25 seconds and then release it.
In case you have an appliance with adjustable heat input, adjust the pressure regulator to the setting
required or set the thermostat on the requested temperature setting to obtain the heat output you need.
If the gas heater goes out, wait for about 3 minutes and repeat the above ignition procedure.
Shut off procedure
Turn down the gas pressure regulator and close the gas valve on the gas cylinder / gas tank / gas pipe. The
gas heater will extinguish now and the safety device will close after 60 seconds. Wait 3 minutes before opening
the gas valve and re-ignition of the gas heater.
Game rearing
Ceramic heaters are used a lot for game rearing. Especially for game rearing, due to the small cages and active
birds, pay a lot of attention to cleaning and ventilation. While the cages are small, the effect of lack of ventilation
and not cleaning will be directly cause the death of birds in a short time. While normally one heater is used for
one cage, we advice to add an independent temperature alarm system for those situations where a temperature
drop due to a (gas)failure will result in bird loss.
