Installation of gas connection must be carried out according to applicable standards and regulations
(see. Chap. XI). Pipeline must be ended by a gas ball valve near the joining point of the infrared heater
– max. 1.5 m (Fig. 40). When the infrared heater is in operation, there must be stable and unwavering
gas pressure guaranteed in the pipeline - NG, P, see tab. 8.1, 8.2 a 8.3. For the connection itself,
flexible gas hose is used. Since the hose withstands the temperatures up to 100 °C, it is necessary to
avoid any contact of the hose with the heater outside the points of connection. The gas lines must be
prepared so as to avoid any contact with direct flame and radiant heat.
Connecting the infrared heater can be carried out only by an authorized person. The gas hose is subject
to periodic revisions as the gas distributions. It is necessary to protect the hoses from mechanical
stresses and aggressive media. The hoses must not be subjected to any tension.
Dimension G* is G1/2” for Helios 10 to 40; G3/4” for Helios 50.

Place the box of remote control according to the project so that it is freely accessible for the servicing
staff. Connection of the box for remote control to the main supply distribution of 230V/50Hz must be
carried out firmly using suitable three-wire cable. Connection of the box of remote control to the heater
must be carried out firmly by the five-wire cable or seven-wire cable if all signals are to be transferred.
Then connect the cable to the terminal piece according to the relevant wiring diagram (Fig. 44-46).
Installation of electrical connections must be made by an authorized person according to applicable
standards and regulations. The installation must include test of functionality and electric revision.
