Webasto Help

[Jim_Scoggins]

Here is a little Webasto info from a guy who lives and camps in Alaska. I shared with him Mango Mikes stuff on Webasto. Thanks Mike.

He sent the following which might help one of us some day.

----------------------------------------------------------------------
It looks like the gremlins have all moved north for the duration. On the
way back from Haines it was the Facet (which has worked perfectly since we
got back) and now the Webasto. Dewey came out this morning to see what the
problem was, even brought a new reset switch in case mine was bad. He
pushed the reset and it clicked. I turned on the Webasto and it fired right
up.



I just about wore my finger out on the reset at Eureka and also tried it
again after we got back to Anchorage with no luck whatsoever. I did find
out what the reset is though. It is an impact switch which trips in an
accident to shut off fuel to the Webasto. Just like an ELT I had in my
Helio, a bump can cause it to close. The only think I can figure is that
it somehow hung up because the heater worked all night although it didn't
seem to put out as much heat as usual so maybe it was partially closed and
just shut completely Sat A.M. If it happens again I think I will beat on it
and try to get it to cycle before packing up and heading home.

I asked Dewey if he would be willing to help forum members with Webasto
questions and his response was, sure, just have them call me, I do it all
the time. In addition to knowing Webasto inside and out, Dewey is a
particularly nice guy.



To give you an idea of his experience, they just ordered 50 Webastos for
vehicles up on the slope and he will be installing them. I would bet he
installs and services more Webastos than anyone else in the US (There might
be someone in Canada who does as much). Here is Dewey's number:



Dewey Robinson

907-274-7795



If you lose the number he is in the Anchorage phone book under Robinson,
Duane M on Karluk St. He does a lot of trouble shooting by phone because
they call him from the slope a lot.



I also learned another thing today; Webastos are available either gasoline
or diesel fired. He showed me the one he has on his Expedition which is gas
fired.



Dewey also told me a bit about the Webasto forced air heaters. I am looking
into replacing one (at least) of my propane furnaces with a Webasto. Dewey
says the largest one will run about 20 hours on a gallon of diesel. He uses
one in his cabin so he doesn't have to get up at night to put wood on. Says
it uses about a pint of fuel to heat all night. He says they are extremely
efficient and reliable and the warranty has been increased from one to three
years.



I realize most of the folks on the forum are probably more into air
conditioning than heat (almost every year we will have a day or two when we
use the air conditioner) but if anyone is into winter camping my experiences
might be helpful so please bear with me as I interject a bit of northern air
conditioning into the discussion.

Jim, We have a 91 Liberty , New to us. I have been trying to figure out webasto. Do you know where it would be located on this coach and do I need it over a pit to get at it. I kind of think valves are turned off, as
coach spent a lot of time in Cal. Judi and useless husband

Judi and useless husband

Judi, I'm just wondering...does he read this? Could you tell us a little more about him, maybe some photos.

About that wabasto location....turn it on and head toward the sound, you'll swear your at a airport, standing on the departure runway.

[Jon Wehrenberg]

Judi,

Call Liberty. They will go out of their way to help answer all your questions specific to your coach.

Get on their mailing list and also advise prevost of your ownership and give them the serial number.

Your H3 (?) is not common, and I can't help you on the layout.

[Darrell McCarley]

Judi, I had a 1989 Liberty at one time. The webasto was located in the front bay, back wall, behind a small removeable panel. I do not remember a switch or cut-off valve but maybe someone with more knowledge will post with more info. It should have a fuel shut-off valve somewhere. I hope some0ne can help. Darrell

[tdelorme]

Judi, crawl in the first bay and look on the back wall. If there is a removeable panel there, most likely the unit is behind it. But, like Dale suggested, flip the switch on and follow the sound.

Since the subject has come up,...
Are the webasto's not the same as an oil burner gun assembly.
I have never played with "or even looked at" one yet, but being a hvac guy the picture of one looks like a cross between my kerosene construction heaters and an oil burner.
Are the nozzles a cleanable 2 piece like the kero heaters or are they like the oil burner type.

[MangoMike]

Ed,

Hope this helps. Although it's claimed that you can use air pressure to clean the nozzle I wouldn't advise it. I tried on one of mine with no success. For $21 why take the risk to freeze your keister off some evening.

Thanks for the Webasto Info -I'll file away. I wonder if the Alaskan Dude had a different model. As I've been all over the drawings for the 2010 and 2020 and could not find a impact switch or similar device.

[Joe Cannarozzi]

Jim great stuff from Dewey.

[wrongagain]

Yup,
Looks like normal oil burner stuff.
Normal looking electrodes and ceramics, photocell.
Looks like a regular delavan nozzle, all you need to know is the firing angle and g.p.h. and it should be a $15.00 nozzle.
And no, you cannot blow out a 1 piece nozzle,... period, all you will do is waste your time and air.
The 2 piece set up unscrews into 2 pieces and basically the act of unscrewing it cleans it.
They are used in low pressure setups.
I have to assume by what I am looking at that this runs at oil burner pressures around 140 psi, give or take depending on setup.
