goes and turn the rotary power switch
(2)
anti-clockwise
as far as it goes in order to set the lowest water volume
and the maximum gas volume.
▶
Open a hot water tap.
▶
Ensure that the water pressure is at least 0.13 MPa
(1.3 bar) during the test.
▶
Operate the product until a steady state is reached (ap-
prox. 10 minutes).
▶
Block off the flue gas route with a Vaillant flue gas re-
strictor, for example. Also observe the documentation
enclosed with the flue gas restrictors.

Conditions
: Gas connection pressure not in the permissible range
Danger!
Risk of material damage and operating
faults caused by incorrect gas flow pres-
sure.
If the gas flow pressure lies outside the per-
missible range, this can cause operating
faults in and damage to the product.
▶
Do not make any adjustments to the
product.
▶
