Part one of the propex thread.
Before I start the rear bench and floor needs to be stripped out to remove the existing heater vents.
The bench seat centre leg will need to be removed to as well.
Between this pic and the next was 2 hours of measuring to miss the chassis legs, floor supports and assorted pipes and cables.
Having a low van and no access to a ramp is making this job much harder than anticipated.
Trial fit.
2x 40mm holes cut through the floor and then the insulation and ply refitted.
The edges of the insulation and ply sealed with aluminium tape to allow the exhaust assembly mastic to fill the hole around the inlet/exhaust ducting and not spread into the floor void.
I cut the holes so that they were right up against the last "top hat" section.
The inlet/exhaust ducting was fitted to the propex unit, copious amounts of exhaust assembly mastic applied to the holes and pipework to seal the openings, and then the unit fixed down.
Gas pipe fitted and Z hinge back in to check clearance. I have plans to duct the fresh air inlet through from the engine bay by the spare wheel well, and then the hot air outlet will be teed off into the original heater vent hole to allow hot air to get to the screen. The vent hole by the propex unit will be sealed shut along with the openings under the van where the heat exchangers connect.
Too bloody cold and dark to carry on today.
Gas pipe install to the swing out cooker and propex unit next.
To be continued.....
