As I had indicated in the prior post…I decided on the specific location of the heater. With the holes drilled, I was able to get the heater in place.
I was able to run the copper gas line up through the existing grommet that was in place for the OEM rear heater wiring harness. I was able to T off the existing gas line that feeds the stove.
In the picture above, you can see the exhaust tube that comes out of the heater box and vents the combustion gases to the edge of the Vanagon. Feeding from the other side of the vehicle is the fresh air intake that feeds into the fire box.
Back into the Vanagon, I modified the kick panel under the rear seat to accommodate the heater. The panel already had a cut out for the OEM heater. That cutout was enlarged slightly and a heater grate was fit over the opening. This serves as the return air vent that feed the unheated area into the heat exchanger. Based on the location of the Propex heater another hole was cut to accept the heater vent that will feed the heated air into the Vanagon.
With the kick panel reinstalled, the duct from the heat exchanger to the kick panel heater vent was installed.
Next up is testing and adding a cover to protect the heater from all of the other stuff that we store under the back seat.
