Differences between 8-10L version and 12L version of the heater

8-10L
12L
The differences between a 8L heater or a 10L heater is just a different fuel nozzle. However the
differences between a 10L and a 12L heater are somewhat more elaborate.
The main difference is that the 12L heater has a bigger burnerchamber (6) not only is it longer the
diameter is also larger. As a result the dimensions of some related parts change as well. First and
foremost is the main shell, the 12L burnerchamber is 10cm longer and so is the main shell (3). The
diameter of the burnerchamber is 37mm larger and as a result the burnerchamber backplate (2) and
the heatshield (7) are aswell.
Because the diameter of the burnerchamber is larger and the (inner) diameter of the main shell is the
same as the 10L, the burnerchamber supports (4) decreased in size.
The most significant change to facilitate a 12L input is the addition of a extra protection shell (5) to
prevent the main shell (3) from getting to hot. Also the air scoops of the air inlet chamber (1) got larger
to provide the flame with more oxygen.
Apart from these differences the 3 heaters are similar, the names of the other components of the 12L
can be found in paragraph 2.2.1
