•

Technical specifications;

 

 

• Water connections, Unvented;

 

 

• Water connections, Vented;

 

 

•

Gas connection;

 

 

• Air supply and flue;

 

 

•

Electrical connection;

 

 

• Checking the supply pressure and burner pressure;

In the event of conversion to a different gas category, see conversion (4 "Conversion to a different gas category").

3.2

Packaging

To avoid damaging the appliance, remove the packaging carefully.

 

 

We recommend unpacking the appliance at or near its intended location.

 

 

 

 

 

Caution
