Michael,
I ran plastic trunking to the mini heater from the vertical vents either side of the main grille in the nose of the car.
It needs to be glassed onto the inside of the grille.
The other end of the two pipes is fed into a tee piece, which in turn is connected to the intake of the heater. Takes a bit of HeathRobinson adaptation to connect the different size pipes but it works.
Certainly I have a flow of air through the heater whilst moving without the blower on, this is great in the winter.
The next step, when I get the car repaired and back from Pilgrim, is to alter the piping to the heater with a water valve in circuit.
This will mean I can have cold air into the footwells in the summer;biss :tu
