Setting The Co₂ Content; Setting Partial Load Mode - Vaillant ecoTEC pure series Umrüstanleitung

Applicability: The Netherlands
▶
Starting from the current position, turn the screw (2)
(2.5 mm hexagon socket) as follows:
–
Converting from natural gas (G25 or G25.3) to
propane : 7 revolutions clockwise
–
Converting from propane to natural gas (G25 or
G25.3) : 7 revolutions anti-clockwise
–
Converting from natural gas (G25 or G25.3) to
natural gas (G20) : 4 revolutions clockwise
–
Converting from natural gas (G20) to natural gas
(G25 or G25.3) : 4 revolutions anti-clockwise
Applicability: Germany
▶
Starting from the current position, turn the screw (2)
(2.5 mm hexagon socket) as follows:
–
Converting from natural gas (G20) to liquefied pet-
roleum gas (G31): 3 revolutions clockwise
–
Converting from liquefied petroleum gas (G31) to
natural gas (G20): 3 revolutions anti-clockwise
–
Converting from natural gas (G20) to natural gas
(G25): 3.5 revolutions clockwise
–
Converting from natural gas (G25) to natural gas
(G20): 3.5 revolutions anti-clockwise
5. Start up the product with check programme P.01 (→
Instructions for the heat generator).
6. Measure the gas connection pressure/gas flow pres-
sure versus atmospheric pressure. You can find the gas
connection pressure in the installation and maintenance
instructions (→ Insutrctions for the heat generator).
1 / 2
Gas connection pressure/gas flow pressure in the per-
missible range
▶
Decommission the product.
▶
Close the gas stopcock.
▶
Remove the manometer.
▶
Tighten the screw on the test nipple (1).
▶
Open the gas stopcock.
▶
Check that the test nipple is gas-tight.
2 / 2
Gas connection pressure/gas flow pressure not in the
permissible range
Caution.
Risk of material damage and oper-
ating faults caused by incorrect gas
connection pressure.
If the gas connection pressure lies
outside the permissible range, this can
cause malfunctions and damage to the
product.
▶
Do not make any adjustments to the
product.
▶
Do not start up the product.
▶
If you are unable to eliminate the fault, contact the
gas supply company.
▶
Close the gas stopcock.

3.3 Setting the CO₂ content
1. If the gas connection pressure is within the permissible
range, proceed as follows.
2. Start up the product with check programme P.01 (→
Instructions for the heat generator).
3. Wait at least five minutes until the product reaches its
operating temperature.

4. Measure the CO₂ content at the flue gas analysis point
(1).
5. Compare the measured value with the corresponding
value in the technical data table.
6. Set the CO₂ content (value with the front casing re-
moved) by using an Allen key to turn the screw (1).
◁
To increase the CO₂ content: Turn anti-clockwise
◁
To decrease the CO₂ content: Turn clockwise

Setting partial load mode

When converting the gas, the partial load mode must also be
adjusted.
Conditions: Converting from natural gas to propane
▶
Increase the current value under D.50 by 100 rpm.
Conditions: Converting from propane to natural gas
▶
Reduce the current value under D.50 by 100 rpm.
