REGULATING THE PRIMARY AIR, MAIN BURNER

- Start up the unit by following the user instructions.
- Check the gas seal with soapy water, ignite the pilot by following the operating instructions and check it. The flame must
invest the thermocouple ; if it does not do so,
- To check the primary air regulation for the main burners, distance "X" should be adjusted in a correct manner (see injector
Table II Ch. 2.5-2.6 and Fig. 5 position C) ; a correct primary air regulation prevents, the flames from lifting off when the
burner is cold, and from returning when the burner is hot.
- Check the inter-ignition and the flame regularity on maximum.
After replacing the nozzles, apply on the existing label the one supplied with the machine indicating the new type of gas.
