Some (hopefully) helpful comments on using your Wallas and posting here: 1. If you post asking for advice, please be sure to include your model number. Not all things are common to all Wallas products! 2. ALL Wallas products can benefit from being started with the engine running or the...

- The Wallas 85D and 95D products are designed for burning diesel and diesel is the right fuel to use (#2 or #1). The Wallas 800 is a kerosene fired device and it should burn kerosene. - When any major overhaul of a Wallas device is performed, the final test before we ship it out is to use an...

Re-priming: If you have run your unit dry in preparation for storage, when you go to re-start after storage, the device will need to be re-primed. To do this, you typically just need to start the device a couple times until it pulls fuel up the line and starts up. When you shut down again, it...

Hardee and localboy: Storage and running out of fuel: When the device has used up all the fuel in the line, it will see a sudden, dramatic drop in combustion chamber temperature and go into shut down mode. In shut down mode, the fuel pump quits running and the fan motors continue (in some...

Please note, in our references to diesel fuels, we find the use of #1 or #2 to be equally acceptable, although in extreme cold conditions, #1 might prove to be the better choice, depending on where the fuel is stored. By far, #2 diesel is the most commonly used fuel for our diesel products. It...

Bill: We really know very little about Klean Heat, since our previous inquiries to the manufacturer went mostly unanswered. It has been identified as a "synthetic" kerosene, but our understanding of what that involves chemically is very limited. We have found that it seems to work well in...

Today, we have been reading this very long and varied thread of comments, advice and concerns. We are very glad to see people exchanging ideas and information about Wallas products, but we need to raise a couple very important topics of concern from our end. 1. There are several models of...

Sorry to be so late on this one. Good luck. We never could find a definitive part number on that motor. The ones from Wallas share the same brand name, but no part number. Be aware that when the process of replacing the combustion fan motor is complete, the whole system needs to be tuned...

We have not heard anything official from the makers of Klean Heat, but we do not have confidence in any fuel other than diesel when held for more than two years. You can rest assured the fuel maker won't be paying for the servicing of your unit if and when the fuel clogs it up. Shake the...

A clarification or two: I made the comment in my last posting that the Wallas stoves and the 40D take their combustion air from the cabin. This is true for the 40D if it is mounted in the cabin. Like the stoves, the combustion air inlet is on the bottom of the unit itself, so combustion is...

Okay, so a LOT of questions, concepts and misconceptions in this post. I will try to clear up what I can: Wallas builds two different lines of marine products, kerosene products and diesel products. All diesel products have a "D" in their name (as in "30D"). The kerosene line is comprised of...

For those of you having trouble with your Wallas not cooking well or quickly, be sure you are using the right kind of pans. Any of the Wallas stoves require the use of pots and pans with a machined bottom surface, since the heat is transferred through contact with the stove top. Revereware...

The Wallas 85D/270 combination is only intended for use as a heating device with the lid down (blower fan running). The current draw and diesel fuel burn for this stove/heater is as follows: Lid up, lowest power setting: .15 amps, 3 ounces per hour Lid up, highest power setting: .25 amps...

* 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...

An Ecofan only helps to move air over a heat source that has no active (blown) ventilation. The Ecofan produces no heat itself. The Wallas stove/heater I will assume you have uses a fairly strong blower to move heat around and can produce up to 1900 watts of heat for you (if it is the model I...

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...

The Wallas 95D series stoves will respond best to several control disciplines to reduce internal sooting: 1. Start with the throttle on high. 2. Make gradual power changes when running. 3. Do not run for long periods on the lowest setting with the lid down. Using good kerosene or Klean Heat...

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...

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...

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...
