Ken: I'm glad you were able to remove the Wallas, and maybe now can be fixed. I had a Wallas stove/heater on my 2010 R-25 (Classic) for some years. The boat was sold some 2 yrs ago and the Wallas stove remains on it and the new owner has had no issues with it.
I loved my Wallas stove/heater. The heating plates/surfaces get very hot and there was one instance where I had a Tupperware box underneath in the cupboard. This box was some 2" away/below from the protected exhaust tube. One day I grabbed the Tupperware box and found it had been severely warped (not melted) and suspect it was due to the heat (radiant) from the Wallas exhaust tube. So my advice is to be careful what you place in the cupboard under the Wallas stove.
The Wallas stove/heater is very efficient, takes up precious little space and serves as a heater when necessary.
It's a shame that Ranger Tugs decided to drop this Wallas stove/heater in favor of electric & alcohol stove. I suspect they did as many/some RT owners were complaining about the Wallas and this may have been attributable to a bad batch of the stoves being release by the manufacturer or simply that the boat owner was not operating the stove correctly... but of course I really dunno.
I loved my Wallas. 😀
P.S.
I actually contacted Wallas about the Tupperware being deformed and this was their reply at the time....
First, thanks for using Wallas! The 85DU/270 stove is a great system,
but imperfect if you don't know a few things that we have tried very
hard to illustrate on the web site and in our manuals.
Concerning the exhaust pipe, this is the first time we have heard about
melting tupperware. A couple suggestions/comments:
- The insulating sleeve over the pipe works well, but can be augmented
with another sleeve over it. That being said, we never recommend direct
contact with soft plastics like polyethylene (Tupperware). Call us and
we can help work this out. I will be at the rendezvous later
today...1-888-606-6665.
- Finally, if there was any kind of impedance in the exhaust line (a
kink (rare), mice (rarer), bats, etc) will greatly increase exhaust hose
temperature (it would also make the stove smoke), but this is a long
shot.
The lockout feature is a very important safety feature. So far, the 85DU
is the only Wallas product with this feature, ut it will be showing up
on future models.
When it locks, it means you have been trying to start the stove and for
whatever reason, it has failed. This could be for fuel reasons,
electrical or other reasons. If lockout did not exist, then some users
would go on trying to start, pumping fuel until it overflowed under the
counter and/or draining the battery completely. Remember, the stove
draws up to 10 amps for four minutes on each start cycle. Call us if you
have questions about why you got locked out.
Here is the unlock information, right from the manual:
* Unlocking the stove:
1. Switch stove ON (lock blinking).
2. Disconnect the main power supply (blinking stops).
3. Reconnect the main power supply (the yellow LED lights up
for 1-3 seconds).
4. When the yellow LED has gone out, switch the power OFF.
5. Switch stove control ON to initiate start cycle again.
Ranger does a great job of installing these units and commissioning
them. It makes our job a lot easier when we have people like Andrew
keeping an eye on things!
