Hi All,
It is the time of the year to think of van heating. I have decided on the gas Truma and just would like to know a few things about positioning of the unit.
Best place is under the club lounge situated over the roadside wheel arches. This would mean the heated air out let would face towards the other side of the van (instead of shooting air down the length of the van). Any problems with this?
Also can someone tell me what is the minimum legal distance of the exhaust outlet from a van window?
Furthermore, is there any need/benefit to put another outlet in the ensuite in a 22' van?
Regards,
Ian

HI Ian,
We have the same unit in our new van and they work well - but only tried it once so far (van is only 9 days old).
Ours is located under the dinette seat and the outlet comes out the back of the seat closest to isle and shoots the hot air straight down the isle towards the ensuite (our seat is located next to the fridge and sticks out further than the fridge so the outlet can aim the hot air down the van).
We only have 1 outlet and that seems plenty - vans are generally well insulated and seems to warm the van in a short time.
You will also need an inlet for the air - ours is located in the same dinette seat but facing inwards towards the table support on the outside end of the dinette.
I do not know anything about the legal distances - but if you have bought one its probably in the user manual.

Cheers

Thanks Wamuranman,
Haven't bought the unit yet. Is your exhaust below the window on the outside wall of the van?
All the best with the new van.
Regards,
Ian

Yes Ian the exhaust (or flu gas vent) is located on the outside of the van below the end of the dinette window. It has a screw on cap when travelling or not in use. (i.e. vent is virtically below edge of window frame).
Must remember to remove cap before use.
I just had a look in my owners manual herte is what it says in this regard (I will quote verbatim so as to not misinterpret) :

"The outside surface must be exposed to wind from all directions and, if possible, there should be no trim strips or covers in this area, mount heater on an appropriate base if necessary.
The wall cowl is to be fitted in such a way that no tank nozzles or tank ventilation aperatures are located within 500mm of it. In addition, no air discharge apertures for the living area or window openings may be located within 300mm of it.
If installing the cowl directly underneath a window that will be opened, installation of an electric window switch is mandatory. The gas unit must automatically switch itself off using the Truma automatic shut-off facility if the window is opened."

Hope this helps.
Cheers
Glen
