27. NOTES FOR INSTALLATIONS WITH SEPARATE OUTLETS

In special cases, installations with separate outlets can generate vibrations that may cause the fumes pressure switch to
trip (fault E03 on the boiler display).
To solve this problems, two slots closed with pre-punched holes (Ref. A and B) have been prepared on the fumes outlet.
These can be easily removed by the Qualified Technical Assistance Service without having to remove the outlet.
Remove knock-out A (Detail 1) and check the appliance works correctly.
If not, remove knock-out B (Detail 2) as well.
