7.6. Conversion to LPG
Conversion is strictly prohibited in some countries, such
as Belgium, which do not allow the double gas category.
The unit is supplied already set for natural gas and with the kit
for conversion to LPG, including:
•
calibrated gas orifice plate;
•
pilot nozzle;
•
adhesive plate "Equipment converted...".
The kit is not supplied in countries where conversion is prohibited.
To convert the unit, follow these instructions:
•
disconnect from power supply;
•
between the gas valve and the Venturi, replace the gas
orifice plate fitted (natural gas) with the one supplied with
the kit (for LPG);
•
replace the pilot nozzle (natural gas) with the one in the
kit (LPG);
•
restore power supply and set the heater up for ignition;
•
while the start-up electrode is sparking, make sure there
are no gas leaks.
When the burner is lit and working at maximum capacity, verify
that the valve intake pressure corresponds to the value required
for the type of gas that you are using.
Perform the combustion analysis as described in Paragraph
7.5 "Combustion Analysis" and check that:
•
the value of CO
2
, at maximum and minimum heat output,
is within the limits indicated for the type of gas being used
(tables in Paragraph 7.2 "Gas Settings Table"). If a differ
-
ent value is detected, change it by turning the adjustment
screw: screwing it down decreases the CO
2
level, loosening
it increases the level.
•
that the gas valve Venturi pipe connector does not leak.
After converting and regulating the unit, replace the nameplate
indicating "Equipment regulated for natural gas" with the one in
the kit that indicates "Equipment converted ...".
7.7. Conversion to gas G25 - G25.1 - G25.3
- G27
Conversion for gasses from G20 to G25 or G25.1 or G25.3 or
G27 is allowed only in countries of category II2ELL3B/P [Ger-
many], II2Esi3P [France], II2E3P [Luxembourg] and category
II2HS3B/P [Hungary] and category II2ELwLs3B/P [Poland].
For countries in category II2EK3B/P [Netherlands] the unit is
supplied already set up and regulated for G25.3.
For
category I2E countries, where conversion from G20 to G25
is not permitted [Belgium], the unit is supplied set for operation
with G20 gas.
Conversion from one type of gas to another can only be per-
formed by authorised service centres.
Conversion to G25 and/or G25.1, G25.3, G27 where possible,
consists in:
•
insertion of orifice plate (according to the gas type and the
equipment model)
After the conversion, relight the burner and:
•
check that the intake pressure to the gas valve corresponds
to the level required for the type of gas [see tables in
Paragraph 7.2 "GAS Connection Tables"];
•
check that the level of CO
2
, at maximum and minimum heat
output, is between the values indicated for the type of gas.
If the value is different, change it by turning the adjustment
screw on the Venturi pipe: screwing it down decreases the
value, loosening it increases the value.
Stick the nameplate "Equipment converted for gas G25...." in
place of the one that says "Equipment set up for ......".
NOTE: Always pay close attention to the level of CO
2
in
G25.1; for G25.1 minimum and maximum heat output in
the LK105 model will always be lower than when used
with G20.
The model LRP102 is not suitable for operation with gas
G27 and G25.1.
NOTE: The conversion kit to G25 , G25.1 and G27 is
only supplied on request. The conversion kit to G25 is
included in the standard supply for France, Germany
and Luxembourg.
For models: LRP018-075 and LK020-080
