Diesel heater installation III.

Finally, after two weeks of intense work, I'm done with the heater installation.
I was doing this for the first time, but if I exclude all that challenging woodworking, it was pretty easy and straight forward project.
Electrically speaking, you have to just supply the onboard power, connect the control panel and that's it.

The exhaust pipe is attached to the hull using one support pad made from the heat resistant material. The bold is going through one layer of that material and the second one is glued with the hole bigger than the bolt head to leave a distance between the bolt and the hull.
Everything was then glued to the hull with Sikaflex.
One remark regarding the exhaust pipe connection. The installation manual doesn't mention it, but when I first started the heater, I saw a little of smoke from the joints so I've applied a little amount of the exhaust cement seal used in automotive.

In the same port locker, there is also a 7 liter diesel fuel tank from Ateso and the fuel pump attached directly to it with the fuel filter. I was trying to follow the installation instruction as possible to keep the right angles on the fuel pipe so the known fuel pump ticking is really inaudible in the cabin.

The control unit was attached in the cabin next to the main distribution panel. It has also the build in thermostat so there no need for more holes.
There is an option to configure the startup mode - heating or venting, startup temperature and so on. You can also configure the schedule for automatic startup.

The electrical installation requires direct connection to the battery to avoid unintentional power cut and to allow the heater to cool down. You can see the small fuse box with two fused 15A for the glow plug and 1A for the heater and control unit.

And finally this is the pictures of the vent outlets in the cabin. One with closable vent in the head, one for the cabin and one in aft berth.

The last thing I would like to show here is the relocated outboard fuel tank to the center cockpit locker.

I hope we will now enjoy more cozy days and nights on our boat.
