CONVERSION INSTRUCTIONS
Fine adjustment jet
Take the cover off the gas control block by unscrewing
the screw (4). Now remove the fine adjustment jet (5).
Fit a new fine adjustment jet and tighten well. Replace the
cover.
Adjusting the burner pressure
Reconnect the gas supply to the heater, if necessary, and
turn the new gas supply on.
Ignite the pilot light and turn the thermostat to the highest
setting. The gas control block has two points of pressure
measurement where the burner pressure and the pre-
pressure can easily be checked with a manometer.
Unscrew the screw (6) at the point of pressure
measurement and connect the manometers.
When converting to propane, adjust the burner pressure
with the pressure regulating screw (A), as shown in the
table.
Check that the pre-pressure corresponds with the
pressure given in the table (pag.25).
Finally, affix a new type plate and replace the casing.
