The heating system consist of

Fresh air is taken from the inlet located on the bottom of the lower

exchanger (5) at the exhaust muffler (4) and further to the selector
boxes (2).
The control valve is actuated via Bowden cable by the CABIN HEAT
control knob located on the right side of the instrument panel.
From the control valve air is ducted to the distribution box (6), where
the air flow is divided. Then further routed through rubber hoses (3)
to the flanges (2) on the left and right side of the firewall (1) and then
