Webasto heater install continued:
Start some reassembly. Glow Plug into the Burner Insert.
Notice that the Glow Plug is slightly oval.

Place the Glow Plug so the wide part of the oval is parallel to the face of the Burner Insert. The wire contacts should face towards the open end of the burner tube.

install the Glow Plug's hold down screw. Don't over tighten it.

How it looks after cleaning.

Slide the Glow Plug wires into the groove on the face of the Burner Insert.

Treat the Rubber Grommets with Armour-All.

Place one of my DIY gaskets into the Heat Exchanger.

Put the Combustion Tube into the Heat Exchanger.

Only fits one way.

Maneuver the Burner Insert into the Heat Exchanger. Mind the metal fuel tube.

As the Burner Insert is lowered into the Heat Exchanger the fuel tube grommet must be slid into place. I've used Armour-All on the grommet so it slides easier.

Be sure it's completely seated.

The two sets of wires are next. The grommets will be fitted into these holes.
Be sure to run the Flame Sensor wire between the face of the Burner Insert and fuel tube.I've highlighted this step since I got it wrong the first time. Didn't realize my mistake until the heater was completely assembled and I looked back at the photos.

Here is the only change I had to make because of the DIY gasket. The yellow wires were originally wrapped around the Spoiler one time. The DIY gasket raised the Burner Insert just enough so the wires made contact with the spinning face of the Combustion Air Fan. This was easily fixed by running the wires under the spoiler and not around it.

Clean off the edge of the Combustion Air Fan where the gasket rests. First with a razor.

Then fine sandpaper.

The fan blades of the Combustion Air Fan need cleaned.

To clean it I used brush,

paper towels,

and finally Q-tips to get in the corners.
