Webasto heater intake on C30

[SJI Sailor]

My diesel heater is not blowing air at all, and I am looking for the intake vent. Can someone say where it is, and the best way to access it? 2019 C30S. There is no obvious intake location.

I am guessing it is only on the unit, in which case what is the best way to get to the unit?

Thanks in advance! BTW it heats up fine, and green light is on , just no air on either heater or fan mode.

Partial success. First, the location of the heater is under the range, underneath the access panels in the storage area. Photo: http://www.tugnuts.com/gallery2.php?g2_itemId=80438

As for the fan problem, it appears that the distribution vent line has come loose from the *back* side of the heater: Photo from my inspection camera: http://www.tugnuts.com/gallery2.php?g2_itemId=80441

So all of the hot air is going into the general hull area under the cabin and spreading out from there. Symptom: it gets hot under the range cover and in the port side storage cubbies.

New question: how do I access the back of the heater? Specifically, can I loosen the second panel and slide the whole unit forward 6-8" while leaving the fuel line, etc., attached?

I am worried that might compress or bend something like the fuel line, but also suspect it may be designed for that because the panel is held with just 2 screws.

On a second look, the loose vent line on the back might be the intake. Need to find the manual! In any case, the question remains: can the unit simply slide forward?

Final update: it is solved (at least for now).

Here's the resolution: the large hose seen in first photo above is the distribution vent. It attaches to the forward end (right hand side in the photo) of the heater unit. It had come loose, so all air was going into the hull area.

There was no need to move the unit. Instead, I had to find a way to reattach the vent and secure it. It requires two hands ... but of course there is no way to access it with two hands. I used a combination of duct tape to hold it temporarily and then reinstalled the clamp ring back on as best I could. Plus lots of, uh, exclamations 🙂

Now we have great airflow again. I figure it might come loose eventually but now I know where it is and what to do, in general.

Hopefully this sequence and documentation will be useful to someone else!

Hi,

Sorry that you had to deal with that. But good to know you were able to solve it. It is rare for these hoses to come disconnected, but things do happen at times. Hopefully it is solved for now. Sorry we weren't able to chime in to help before you found it, but glad you did regardless.

Cheers!

Ralf

Thank you, Ralf! At least I learned something along the way (and fixed it before winter 🙂 )
