Conversion of the stove to a different type of gas for top burners consists in:
• Nozzle replacement in gas burners - nozzle diameters for the respective gas are given in the tables un-
der the heading „Characteristics of burners"
• The aluminium sleeve in the burner body is fixed accordingly - unscrew the screw fixing the burner
sleeve, slide it out or slide it into the body to the position consistent with the table „Setting the burner
shutter".
• Adjust the minimum flow in the control cock - by screwing or unscrewing the screw next to the pilot
valve mandrel, adjust the gas flow so that the flame does not go out when the knob is turned from full
flow to minimum flow setting and has approximately 1/3 of the full flow power.
• Adjusting the gas flow at the pilot burner:
1. If you convert the stove from natural gas to propane gas or LPG, unscrew the sealing screw on the
bottom of the pilot pilot, then remove the pilot nozzle with the feature 40 and screw in the nozzle
with the feature 20 all the way (in case of propane or LPG, the same nozzle is used). Then screw in
the sealing screw. (Fig.18 item 5) Light the pilot burner. The flame should heat the thermocouple
and burn with the bright flame. If this is not the case, adjust the airflow using the shutter at the top
of the pilot.
2. If you convert the stove from propane gas or LPG to natural gas, proceed as described in point ‚a' ,
and then screw out the pilot nozzle with the feature 20 and screw in the jest with the feature 40 as
the way.

Attention! After conversion of the stove to another type of gas, stickers packaged with the nozzles, specify-
ing the type of gas for which the stove is adapted, should be put on the nameplate and the warranty card.
Example: Convert the stove adapted to combustion of LPG into combustion of natural gas. After the co-
nversion, the sticker G20 2E (20mbar) packaged with the nozzles should be put on the name plate (Fig. 17
item 1, Fig. 19).
