Early Cerbera Heater Box
Discussion
You dive into the passenger footwell, pull the carpet covered end board out. Remove the various control boxes that fall out noting connections. Then rummage up behind the leather covered scuttle trim over the footwell on the left hand side to find one wing nut - undo that and a pozidrive screw on the right hand side by the knee vent, then the scuttle panel should come down and out.
Next remove the carpet from the left side of the footwell, untape the looped door release cable and you will see several lines of gaffa tape which are covering the edges of rectangular fibreglass panel. Buried under the tape are several small pozidriv screws. Undo those and a couple of large screws that hold the motor bracket and the panel will come away revealing the motor and box containing the heater matrix inside the cavity in the nearside wing, and in my case no less than 3 carrier bags full of dry leaves!
To unsieze the motor I ended up partly draining the cooling system (use a thin tube to siphon out of the radiator drain plug) then disconnecting the two hoses to the heater matrix, the hot air duct to the dashboard and the electrical connections to the motor, then removing the air box with motor attached. The matrix comes out with the airbox. Reassembly is the reverse etc etc.
ETA - Looking at the manual I have just described prety much what it says. How is yours different?

I must be looking at the wrong manual then somewhere along the line because it said to take the front wheel off and there was a hatch in there to undo... Then the heater pipes went under the heater box... mine dont go through there... I'll have a look see if i can get the heater box out next weekend... I'll let you know how i get on!!

Second half of the pdf deals with the heater.
The kick panel it tells you to remove is inside the passenger footwell not the wheel arch. It is a bit ambiguous on first reading
Some card seem to also have an access panel in the wheel arch its self, mine didn't and I ended up wiggling the whole hot air box out through the footwell. IT was tight but do-able.
