Truma fire

Does anyone know the best way to clean between the fins on a Truma heater?   I can get the cover off enough to dust around a bit but am concerned that if I remove the cover completely I won't be able to get the control spindle back in.

Ours is probably a much older model than yours, but I've dismantled and reassembled it without much of a problem.

On ours, the plastic control rod just drops down inside the casing until it hits the metal control spindle, whereupon I feel the flat on the spindle by lining up the 'OFF' mark on the knob and casing and wiggling until it feels right, then push down.

Voila. (just practising me French in readiness) 

Make sure 12v is switched off.  Pull the gas control knob out of the top.  Unclip the front the swing the top outwards and pull up, that releases the front but don't pull away from the fire until you unplug the cable to the fan controller.

If you are still uncertain I'll take some pics.

Thanks Peter,

I'm still worried that I'll snap the little metal clips.   They look really fragile.   I wondered if maybe I could just poke a pipe cleaner in through the grill on the cover and do it that way.

It took no more than 5 mins to take to bits photo and put back together.  All the bits are robust.

Peter, good photos there but after more than 5 minutes studying them, I'm still a bit lost to do ours.
I'm rather confused, as it looks like the fan controller switch on your Truma is on the left and I take it that the gas control button is on the right.
Our Truma has Ultrheat and it appears the controls are reversed/with an extra sliding switch on the front of the fan controller. I imagine there must be an extra connection for that as well.
Can I also just ask the technique for unclipping the actual cover itself.
Thanks, (an ignorant) nuevoboy.

Grip either side at the top and pull (* Inappropriate Word *) and it comes off. It is explained in the Manual, do you have it? Then lift clear of the bottom clips.

AS don't but some dealers add fixing screws for the cover - see link above.

Assuming any screws removed grip both sides at the top and pull firmly away from wall - you have to overcome the resistance of the clips.  It will only come out about and inch.  You then need to gently push down each clip in turn whilst pulling the cover off them.  It is then free to lift off the bottom location points.

Reinstallation is by feeding the gas control wire through the aperture in the top of the cover, locating the bottom of the cover on the location points and then pushing the top back into place, manipulating the clips down a little to locate them.

If you don't feel competent to do it then don't but getting in there is the only way to clean it properly.  I have to do it often as we carry two cats and their hairs get in there.  NOrmal dust shouldn't need such frequent attention.

Our last Motorhome was a Pollensa. The Truma heater use to rattle like hell whenever we were on the move! So I use to remove the cover every journey and put it safely on the floor between the shorter seats and under the table. Very easy to do and silent running every time!
Now we have a Broadway we have other annoying rattles emanating from the cooker - I have been tempted to strip it down and leave it at home!:

Don't you just love modern PC filters. The * Inappropriate Word * above was either "y a n k" defined as "to pull or remove abruptly and vigorously" or "j e r k" defined as a quick, sharp pull, thrust, twist, throw, or the like; a sudden movement:

Just in case any one things I used something offensive. 

It's a familiar debate

Many thanks Peter.   Gives me the confidence to have  go!
