4.6.2.2 Changing to a different type of gas
!
WARNING
Changes are only to be carried out by a rec-
ognised specialist!
After changing to a different type of gas, the
adjusting device must be sealed.
The boilers are preset at the factory to natural gas H
(Wobbe value 15.0 kWh/m
3
).
Changing from natural gas H to natural gas L
Changeover to low-calorie natural gas can be performed
easily. All you need to do is check/correct the CO
2
(O
2
)
value at at maximum and minimum output (see chapter
4.6.2.1).
Changing from natural gas H to liquid gas propane
Compliance with the special local provisions
(VKF/DVGW/ÖVGW) for operating a boiler on
liquid gas is imperative in each case.
Ensure that the fuel type in the measuring de-
vice has been set correctly!
The conversion kit for liquid gas propane consists of:
- 2 yellow “Change of set gas type: liquid gas” stickers
for the data plate
- 1 sticker with the performance data for propane liquid
gas type
- 1 "liquid gas" gas pressure monitor
- “Notes” package insert
A)
For a boiler which is already connected:
- Close the gas cock
- Set the blocking switch to “0” and disconnect the heat
generator from the mains (e.g. main switch, fuse).
B)
Remove the boiler cover.
C)
Dismantle "natural gas" gas pressure monitor and fit new
gas pressure monitor for "liquid gas". Wire gas pres sure
monitor (AMP connector at positions 1 and 3).
D)
Stick the yellow “Change of set gas type: liquid gas” stick-
ers to the following places:
- A sticker on the gas valve
- A sticker under the data plate
Attach sticker with the performance data for propane liq-
uid gas on the data plate (cover performance data of the
data plate, see “Notes” package insert).
The adjustment value is calculated as follows:
Setting value E =
Heat load NB (kW)
Operation calorific value H

(kW/m

)

The gas flow rate is corrected by changing the fan speed:
- Increase in the max. fan speed at the automatic func-
tion device: -> gas flow rate increases (at constant
CO
2
(O
2
) value)
- Decrease in the max. fan speed at the automatic
function device: -> gas flow rate decreases (at con -
stant CO
2
(O
2
) value)
c)
Use the "-" key to set the boiler to 0 %.
Check the CO
2
(O
2
) content of the flue gas. It must be bet-
ween CO
2
= 8,5 - 8,8 (O
2
= 5,9 - 5,5) vol.-% (dry). Correct
the CO
2
(O
2
) value if necessary by turning the offset screw
D (remove the protective cap first).

d)
Measurement of NOx and CO content. The measured
va lues must meet the limiting values prescribed by the
regulations. Values exceeding these reference va lues are
an indication of faulty burner setting, gas bur ner or heat
exchanger contamination or gas burner defect.
!
WARNING
If the limiting values prescribed by the regu-
lations are exceeded, the boiler must be
put out of operation and the corresponding
meas ures for repair work must be initiated.
After a correction, the upper/lower limit should be approa-
ched again for testing/correction purposes.
The boiler is now correctly set. To return to normal opera-
tion, press "RESET".
