Gas settings
7.4.1
Factory settings
The EC five has been set to the nominal heat load by the manufacturer.
Gas type G20 (natural gas G20 with Wobbe index W
oN
= 15.0 kWh/m
3
)
The specific set gas type can be seen on the optional label glued to the
burner. The factory setting data must be checked against the on-site
supply conditions before installation of the EC five.
7.4.2
CO
2
content
The CO
2
content in the exhaust gas must be checked during
commissioning and during regular maintenance of the boiler, as well as
after reconstruction work on the boiler or on the exhaust gas system.
CO
2
content during operation see section
Technical data
.
Caution
Risk of damage to the burner!
Too
high
CO
2
values can lead to unhygienic combustion (high CO
values) and damage to the burner.
Too
low
CO
2
values can lead to ignition problems.
The CO
2
value is set by adjusting the gas pressure at the gas valve. If the
EC five is used in areas with fluctuating natural gas composition, the CO2
content must be adjusted in accordance with the Wobbe index at any
given time (ask the gas supply company).
The CO
2
content to be set can be decided as follows:
CO2-content = 9,3 - (W
oN
- W
ocurrent
) * 0,5
Important
The air quantity set in the factory must not be changed.
7.4.3
Changing over from natural gas to LPG and vice versa
Danger
Risk of death from gas
The gas type of the EC five may only be changed by an approved
heating specialist.
To change over to another type of gas, the CO
2
content must be reset by
turning the adjustment screws on the gas valve. In addition, the
parameters listed in the following table must be set according to the given
