Sprinter Motor Home part 6:

Moving on with the sprinter build:

Next, I had to install the oven.

I purchased a Thetford Duplex oven, without grille as I had a single hob build into the sink fitted in the last post.

Needing to save space finding somewhere to fit the oven was easier said than done.

I decided to install it under my bed at the back of the living space.

It will have a large wide draw about it which will help keep the heat down and from heating up my bed.

I build a wooden frame that was a tight fit around the oven and slide it into place. The oven is held in place with 4 screws.

The oven is half sat on the wheel arch which adds some extra support.

I then added a step for access to my bed at the back fo the van.

Under the step on the end of the wheel arch box, I have mounted my 230v fuse box.

I then painted the whole lot of grey. The grey paint will not be seen when the build is finished.

Next I cladded the bottom box to the side of the oven ready for fitting electrics, plug sockets, switches and heater vent oulets.

After a lot of woodwork, I decided I would change things up a bit and fit another one of my Armplate security plates to the sliding door.

I have a set (one for each door) and I will be fitting them one at a time.

As they take time and concentration and are very fiddly so its best to be calm and focused and spread the fitting out over a period of days.

Back to the electrics:

Next, I fitted the 230v fuse box and fitted length of cable from the blue 13AMP plug I mounted on the step above the tow bar.

I fitted the 230v fridge power supply that came from Thetford with the fridge.

Then installed a 20amp connect and forget leisure battery charger, both wired in through fused spurs for added protection.

Once these components were fitted to my satisfaction I clipped all the cables up out of the way.

Moving on from this:

Next, was to fit the Propex LPG heater.

So, with very limited space to cram all these items into this van build I decided the gas heater would have to go in the bottom box next to my kayak.

From intensive research, I do not believe where I have situated the heater will be an issue.

I have plenty of vents in the floor and the heater outer casing should not get massively hot to the pint it will cause a fire or melt the front of my yak.

Once everything is up and running I will test this with an infrared thermometer before being 100% happy and calling the heater install finished.

Anyway, I had a measure up and drilled the holes in the floor for the air in and exhaust out that fix to the bottom of the heater.

I cut the holes in the floor using a hole saw for this and attache the two vent pipes.

I crawled under the van and fitted the exhaust first.

Away from anything else so heat would not be an issue.

Then fitted the fresh air intake pipe as far away from the van exhaust and the Propex exhaust as I could.

I sealed these both with high temp sealant where they dropped down from inside the van.

Air Vent:

Next, I decided where I could fit the cold air inlet and two hot air outlets in the bottom storage box keeping everything as neat and compact as possible.

I cut out the three holes with a hole saw and fitted the feed pipes in place using the two-way splitter for the hot air outlets.

I then poked the pipes through the holes and fitted the grilles and screwed these in place.

Finally fixing the heater body to the floor and fitting the thermostat in the most appropriate place I could get the cables to.

Lastly clipping all the air pipes in place stopping them from rattling around in on the road.

Finally for this post:

My underslung LPG tank had arrived.

I thought now was as good a time as any to install it.

Whilst I still had plenty of space to get in the bottom box and drill some more holes.

I drilled a hole to get the main gas feed up from under the van in the bottom storage box. This is where the manifold would be supplying the gas hob, Propex heater and oven.

Once this hole was drilled.

I marked out the brackets on the underside of the van and fitted them using the supplied fitting kit.

This was very straight forward as there was only one place the tank could go.

tank fitted.

Once the tank brackets were fitted I lifted the tank up with some helping extra hands and bolted the tank in place.

LPG Tank:

The next item from the kit I decided to fit was the tank filling point.

I decided I really wanted this on the tow bar with all the other filling points.

Luckily I had order 6m cut to length LPG filling hose.

So I had just enough to run it from the tank to the rear tow bar of the van.

After making a stainless bracket. I bolted the filling hose to this finally bolting the bracket to the tow bar using stainless bolts.

Next, I fitted the regulator to the LPG tank.

Then fitted the copper 10mm pipe to the regulator and up through the hole I drilled in the bottom kayak box.

I then fitted the 3-way manifold to the main gas supply coming up through the floor.

Lastly, I had to fit the supply pipes for each appliance. Starting at the manifold and working my way through the van.

Connecting the oven, hob and heater as I got to them.

Finally clipping al the pipes in place to stop them rattling around and working loose.

One final and very important step:

I filled the tank with air from my compressor in the garage. using an adaptor I purchased from the internet for just this task.

it worked just as described and did the job for which it was intended very well.

Once the tank had as many psi squeezed into it as my compressor would pu
t out. I opened the supply tap on the LPG tank and all the valves on the 3 way manifold.

Going around spraying each joint with leak detection spray and watching carefully for any bubbles.

this from the filling point all the way to each appliance TWICE. For good measure and I could not find any leaks.

I then left the hob on
. To let all the airt pressure out slowly whilst I went off to start the next task.
