2.7 Gas connection
BEFORE INSTALLATION, CHECK THAT LOCAL CONDITIONS OF SUPPLY, GAS TYPE / PRESSURE AND
EQUIPMENT SETTINGS ARE COMPATIBLE.
 Gas piping must not :
- be located in the heated area around a heater (see diagram below).
- produce any stress on the injector block. (Use preferably a metalic flex 12 Gf)

2.8 Electrical connections
See diagram of a standard installation. (§2.2, page 4)
 Use a NEUTRAL conductor or provide an ISOLATION TRANSFORMER.
 All heaters must be properly GROUNDED.
 Control : SX heaters are controlled by VisioLon Ind-T programmable controller.
Refer to the technical instructions.

2.9 Start-up
 Gas-tightness test for industrial installations : (see diagram on next page)
a) Ensure that the installation is at a pressure (nitrogen or dry air) equal to 1.5 times the
gas operating pressure.
b) Turn off the nitrogen or dry air supply and wait 15 minutes for the pressure to stabilise.
c) Check the pressure on the pressure gauge.
d) After two hours, the pressure gauge needle must still show the same pressure.
e) If pressure has dropped, detect leaks , fix them and repeat the operation.
 Clean out
Aim: flush out impurities in gas piping
Clean out gas piping with dry air or, better, with nitrogen, AFTER DISCONNECTING ALL
ACCESSORIES.

 First start-up
a) Preliminary checks:
* calibration of control unit fuses.
* ground-fault breaker operation ("TEST" button).
b) Initial settings:
* main gas valve closed.
* individual valves open.
* ground-fault breaker set to "ON".
* thermostat or programmable controller set to correct temperature setting.
c) Ignition
* manual operation
- open the main gas valve.
- start the heater ignition cycle.
- if the flame is not lit after 45 seconds, start a second ignition cycle
- if the flame is still not lit or goes out, refer to chapter 5
(REPAIRS).
* automatic control
- open the main gas valve.
- check the settings (temperature, time).
- change module programming if required.
- run a full heating and cooling cycle and check:
. ignition cycle length (45 seconds maximum).
. ignition and shut-down of heaters according to temperature settings.

3. RECEIPT OF INSTALLATION
TO BE PERFORMED BY THE INSTALLER IN THE PRESENCE OF THE CUSTOMER.
 Check that the gas type and pressure comply with the type of heater installed
(see rating plate)
 Check that an individual valve is installed prior to each heater.
 Check that the "SX USER GUIDE" (Manual operation or Automatic control) is displayed next to
the control unit, after being stamped by the installer.
 Provide the customer with a copy of each SX USER INSTRUCTIONS supplied in the product
boxes.
 Indicate to the customer the locations of:
- valves.
- electric switches.
- control units.
 Explain to the customer how all control units operate.
 Plan the initial maintenance visit (1 year after start-up).

15
4. MAINTENANCE
LIST OF OPERATIONS TO BE PERFORMED DURING THE ANNUAL MAINTENANCE VISIT.
 Removal of dust from heaters
- on site, without disassembly, heaters off and cold.
 Check condition of ceramic plates (visual inspection).
 Check heater fixture.
 Check tightness of accessories.
 Check heater operation.
Switch on all heaters, check ignition and combustion. A combustion temperature of
approximately 900°C (uniform orange red colour) ensures heater cleanliness and correct
gas supply pressure.
 Check operation of solenoid valves.
Check that all solenoid valves properly close (heaters switched off).
 Check controls.
 Check all settings (do not forget anti-freeze setting).
