3.3 SIZING OF COMBUSTION AIR AND FLUE PIPES
M C series warm air heaters are approved for installation in one of the following ways:
-
C
12
type installation: expulsion of combustion products and intake of combustion
air are wall-based, via separate (see Figure 4 on page 18) or coaxial (see Figure
5 on page 18 and Figure 6 on page 19) ducts. In this way the appliance is sealed
off from the room in which it is installed.
-
C
32
type installation: expulsion of combustion products and intake of combustion
air are roof-based, via separate or coaxial ducts (see Figure 7 on page 19). In
this way the appliance is sealed off from the room in which it is installed.
-
B
22
type installation: intake of combustion air takes place in the room and
combustion products are expelled outside via a specific duct, which may be either
horizontal or vertical. In this way the appliance is not sealed off from the room
(see Figure 8 on page 20 and Figure 9 on page 20).
