Connect the heater to the gas pipeline. Open the gas valve in front of the absorber 

and check the tightness of the gas pipeline and the threaded connections of the 

emitter (after the gas valve) with a soapy solution at the rated gas pressure. Elimi-

nate gas leaks when detected.

»

Check the gas pressure in front of the heater. The gas pressure must comply with 

the value specified in the paragraphs.

»

Check the operation of the boiler and the ignition electrode of the heater and 

whether there is a spark.

CAUTION! Before connecting the emitter to the gas pipeline, the inner surface 

of the gas pipeline must be cleaned. The gas supply valve to the emitter must 

be closed while testing the strength, tightness and control pressure of the gas 

pipeline, otherwise this may damage the valve block.

Check the operation of the boiler and the ignition electrode of the heater and 

whether there is a spark.

Attention! If the emitter does not start within 30 seconds, the gas supply to the 

emitter is cut off. To restart the transmitter, you must not turn off the transmit-

ter’s power supply and turn it back on after 10 seconds at the latest. If ignition 

of the gas-air mixture has not occurred after restart, the emitter should be 

disconnected from the power supply and the valve in the gas pipeline upstream 

of the emitter should be closed. After that, it is necessary to find and eliminate 

the fault and perform a test run of the heater according to the troubleshooting 

and troubleshooting section in the manual.
