31. Design information
1)
Marking "x" indicates that all components of the ue are surrounded by combustion air and meet increased requirements for gas
tightness.
2)
For types B23 and B33, the combustion air is drawn from the installation room (open ue combustion equipment).
For type C, the combustion air is drawn through a sealed system from the outside (balanced ue combustion equipment).
