8.1. G as Conversion
Gas conversion (Natural Gas-LPG) by replacement of gas throttle washer, amending gas pressure settings
(capacity settings) by gas valve, and changing P01 parameter from service parameters are performed. Natural
gas and LPG parameters are given below. There will be a stamping of the diameter and the last 3 digits of stock
code on gas throttle washer (if there is no stamping, marking with colored pen).

Figure 19 . Gas Valve
Maximum and minimum gas pressure adjustment
procedures are listed below. Adjusting maximum egress
pressure;

Remove the front panel and pull the control panel down
to front.

Set the boiler to maximum operation mode (testing
mode). (Testing mode: It is activated by pressing on CH
temperature increase and decrease buttons (button 4 and
6 on the control panel) for 5 seconds)

Turning "1" the maximum gas setting point slowly
clockwise increases gas flow going to
the burner, and the contrary reduces it.

When adjusting settings, C02 value is checked by the
emission boiler.

When C02 value is in the range given in the chart,
maximum gas setting is completed.
Required Equipment: 4mm Allen tool
Minimum Exhaust Pressure Adjustment;

Set the boiler in the minimum operation mode. For
this, press the CH temperature increase button (button
6 on the control panel) when the boiler is in the testing
mode.

After removing the protective cover of the screw for
"2" minimum gas setting point shown on the photo,
turning it clockwise increases gas flow and
anticlockwise reduces it.

When adjusting settings, C02 value is checked by
the emission boiler.

When C02 value is in the range given in the chart,
minimum gas setting is completed.

Pay attention to put back the cover of “2” minimum
gas pressure setting regulator after completing necessary
adjustments.

Remount the front panel and the control panel, which
were removed earlier.
Required Equipment:
T40 Tox Screwdriver
