Kleen-Heat

In following the thread of this conversation, we are quite concerned about the topic of kerosene fuels and Klean Heat. Please take a moment and go to our web site describing the correct use of fuels in Wallas products:

http://www.scanmarineusa.com/techtalk_fuelcomments.pdf

In any case, please pay close attention to the following:

1. Kerosene products have a maximum shelf life after manufacturing of 12 MONTHS. As far as we can tell from the manufacturer of Klean Heat, this limitation is true for them as well. One reader/poster here commented that they believed to have purchased a "lifetime supply". This is a mistake that can cost you a great deal in stove repair once the fuel gets old.

Please give us a call if we can be of assistance.

2. Many posters are commenting here without identifying their stoves by model number, Since Wallas builds both kerosene only stoves (model 800 and model 100) and stoves that burn either diesel or kerosene products (85D, 95D), recommending the use of diesel or taking such a recommendation without clear knowledge of the model is a problem. Diesel will not burn successfully in a kerosene only unit!
 
Doug, thanks for your post. We appreciate those that provide support here, provide info (even if the question wasn't asked in this case), and stand behind their products. My Wallas is running fine but I don't use it much. Will replace the fuel supply this year, it's about 2 years old.

Here are some more comments we hope you will find helpful:

1. Regarding diesel stoves, the 95D (AKA 95DU, 95DP, 125DU, 125DP), these stoves will benefit from the use of kerosene or Klean Heat in one or two ways. One is if the stove is to be used a majority of the time running at low power and with the lid down. Since the blower for the lid on these models only runs at one speed (full), it can overcool the system under this kind of usage. Under these circumstances, kerosene will soot less than diesel. If you run on diesel, just set the power control no lower than about 1/3 power when you have the lid down and running for long periods. The newer 85DU or 85DP stoves fitted with the 270 blower lid do not suffer from this issue, since the blower lid speed changes with the power setting.

2. The 95D series machines also used an older, simpler start sequence than the newer 85D products do. This means that setting the power know to full on the 95D series helps make for a quicker, cleaner start. The 85D units ignore any and all commands once the start sequence is initiated, so the power setting is unimportant.

3. This is recently updated information:
We consider Klean Heat and kerosene to be the same as one another in terms of handling, however the manufacturer of Klean Heat states that the product should be stored at below 90 degrees F and can be held for up to three years under ideal conditions.

4. Storing the boat/stove/heater: If you know you will be putting your boat and or the stove/heater for more than two months, our best advice is that you start the device and get it up to temperature. Remove the fuel line from your tank and run the device until it quits for lack of fuel. This is a good time top inspect your fuel filter. The bronze filter inside your Wallas tank can be removed and soaked in a solvent like acetone or MEK and then blown out with an air hose. You will need to re-prime when you get back to boating.


Thank you for using Wallas!

Doug,

Thanks for the fuel information. I have had zero problems in two plus years of using Klean Heat in my single burner Wallas. For what it's worth, I've never used fuel more than a year after purchase, and I add a little alcohol to the fuel. (Any way to tell date of manufacture when you buy the stuff?)

I do have a question about the stove itself, though. Where on the thing does it tell me whether its a Model 800, 100, 85D, 85DU, 85DP, or 95D (AKA 95DU, 95DP, 125DU, 125DP)?

Thanks,

Bill
 
just to muddy the waters, I have an older model 800 single burner paraffin stove that I've been burning paint thinner in. The stove seems to like it, is there a better, hotter fuel?
 
My Wallas 95D has the model number sticker on the front of base of the unit on the countertop.

Okay, here we go:

The 95DU (flush mount) and 95DP (surface mount) stoves were most commonly sold with a 25E blower lid attached. Part of the time, these products were marketed under the names 125DU and 125DP respectively. The image and description from Socrateur is correct. Thanks, Socrateur!

The 25E lid on the 95/125 series stoves came in two finishes - a tooled metal one on the newer units and a veneer wood one on the older ones. These lids have wood handles on the right and left sides of the lids.

The 85DU (flush mount) and 85DP (surface mount) stoves are most commonly sold with a 270 blower lid attached. They have always been marketed as the 85DU/270 and 85DP/270 respectively. The model and serial numbers are located under the front right side of the chassis. You should be able to see it if you look under the cabinet on the DU versions, as this is an angled plate.

The 270 lid has always had a single wood handle across the front edge of the lid. It has always had a brushed stainless steel finish. Earlier models had a short pigtail cord that plugged into the rear housing, making the lid removable, while the newer ones have no cord and are fully captive in their design.

All of the above products can run on diesel #1, diesel #2, kerosene and/or Klean Heat.

The 800 stove (kerosene or Klean Heat only) has an identifying label on the stainless surface surrounding the circular cast iron cooking surface. Most of these sold were fitted with the 220 heater lid. The lid is about 3" high when closed, much higher than either of the diesel stove lids when they are closed.

There is an older model 100 kerosene stove that has a label on its top which clearly identifies it. Please visit our web site at www.scanmarineusa.com, where you can identify any of the current products by their images.

We hope this helps. It helps us tremendously when you call with service questions if you have the model number and even more if you have your serial number!
 
B~C:

The simple answer to your fuel quesion is this: Kerosene makes good paint thinner, but paint thinner is not typically kerosene. Most often, paint thinner is made (partly) of mineral spirits, which sometimes burns well in kerosene stoves/heaters, sometimes not. Many paint thinners are NOT 100% mineral spirits, incorporating other chemicals not welcome in a Wallas.

100% mineral spirits will generally run well in Wallas stoves, but two things are important to keep in mind:

1. Mineral spirits come in a variety of grades. Some work well, some don't. Low smoke/soot mineral spirits are graded as such for use in lamps with wicks. These differ greatly from Wallas products, but this kind of product may work fine in a Wallas.

2. Manufacturers of paint thinner carry NO obligation to make sure what they are packaging will work in your stove or furnace, only that will thin paint well.

Here is what we recommend: In Wallas kerosene products, use either fresh 1K kerosene, Klean Heat or JP4 direct from a seaplane float. In Wallas diesel products, use any of the above or diesel #1 or #2. Diesel #2 can come from either the fuel dock or fuel station on land.

Thanks for using Wallas!

Thanks for the info Doug.. Several years back Karl (I think that was his name) was pretty firm on using the 100% mineral spirit version of paint thinner, it's good to know that I can use the cleaner, oderless, Klean Heat. Does anybody have any paint they need removed? I have some extra paint thinner to get rid of

I sure appreciate your looking in here and offering up answers
 
Of course one can always ask the question as to when the kerosene or other fuel was actually manufactured? Often it will sit in barrels, or tanks for some peroid of time. When purchased in bulk the date of manufacture is unknown.

No Jp4 seal plane floats in this part of the world--
 
I went fishing around under the cabinet and located the model & serial number of my 85DU prior to dropping it off today. Good to have definative info on what fuel will work. Mahalo for the info.
 
The manufacturer of Klean Heat states that it has a shelf life of three years under ideal conditions. If it is older than this, your fuel should be considered over age and discarded for new.

Klean Heat is good fuel. Unfortunately, the stove may seem to run fine and the fuel will look normal when fuel is old, but it can bring about early need for servicing.

Thanks for using Wallas!

We find that the Wallas works great on the new ultra low sulfur diesel, plenty hot, no soot or odor. Available at your local gas station. $2.11/gallon!

I totally agree ULSD is your best choice; recommended by the manufacture and Scan Marine in Seattle.
Sure it smells if it gets on you, be carful and it’s not a problem.

It burns incredibly clean, no soot at exhaust port.

If you smell diesel under the cabinet it’s usually from the tank vent line, this dissipates quickly and won’t occur if you remember to leave the cabinet doors open when boat is vacant for extended periods.
 
I ran diesel for the first 3 yrs. I did use a conditioner in the tank, but still
had 'microbe scum' inside it. The filter was not affected. I guess the heat
and humidity here in Virginia Beach just took its toll.

Rather than be without the heater in the fall to spring time line, I bought
another tank and filled it with K1. This K1 was in sealed 2.5 gal containers
which I store at home. The new tank has been filled and in service for 2
yrs now. I do inspect it and have conditioner added.... so far so good. I
try to buy the K1 on sale in the summer and usually get 2 containers for
the season.

This may not be practical for some, but I am 30 minutes from the marina.
I have cleaned the original tank and it is ready for an exchange when
needed. The nice thing about this for me is as clutzeeeee as I am, I have
not had to clean up any spilled fuel in the cabin. It also allows me to
keep track of the fuel status.

I sure love this Wallas. It has been so reliable, it has been in use since
Oct 2004. I have used it to heat the cabin underway and while I've
worked in the boat on the work rack, made coffee & tea and cooked.
Yes, the First Mate has full approval....

Hello Art,

Please tell me what conditioner you use in your Wallas fuel.

Thanks,

/david
 
Dave,
I will have to get to the boat to verify it, but it was bought at WM as a
diesel fuel conditioner. It did not take very much given the small volume
of 2.5 gals in the Wallas fuel tank. I think it may have been one of the
Star Brite products... (I say that ONLY by a short memory.) As I recall I
looked for something to prevent moisture and microbe growth... The tank
lining did have a scum on it after the 3 years, but the filter was fine and I
did not have a working issue with the Wallas.

I have K-1 in th tank now for abt 2 yrs with the same conditioner and
the tank lining is still like new with no signs of moisture that I can detect
in my simple ways.
