INFORMATION
Carefully follow the instructions as described in the adapter set.
When the resistance of the flue pipe and air supply pipe increase, the appliance
power will decrease. The maximum permitted reduction in power is 5%.
The resistance of the air supply pipe and combustion gas flue depends on:
▪ the length,
▪ the diameter,
▪ all components (bends, elbows,...).
The total permitted pipe length of the air supply and the combustion gas flue is
indicated for each appliance category.
