This describes running in Thermo Mode (light in the bottom left of the control panel ON). Whenever you start a Nordic Dt, that light will be off, indicating it is in Manual Mode - a simple throttle control, best for cooking, but you can heat that way too. Twisting the knob quickly...

The earlier Wallas 95D and 125D stoves and stove heaters used brushed fan motors. The hallmark of running brushed motors is that they slow down over time. These units would see significant rpm drop after 500 to 1,000 hours of run time, making for a corresponding drop in combustion air, making...

Running a Wallas stove for heat without a heating lid or without the lid in the down (heating) position will eventually destroy the electronics by thermal transfer. Please don't do that, since a thermal drive fan will not solve that problem. The newer (post 2006) stove/heaters have lids that...

No. The correct fuel to air mixture must be maintained and there is truly no way to do that manually. Call us. Q&A are free. Doug@Scan 1-888-606-6665

It sounds like your Wallas needs servicing. If it hasn't been in lately, it might be time. Thanks, Doug @ Scan 1-888-606-6665

This sounds like a great opportunity. I will be gone the last half of June and the second week of August. Let us know when you would like to set this up. Thanks! Doug at Scan 1-888-606-6665

Boomer: These look like a very nice set of pans. While we can't see the bottoms of them in the imaging, but it appears they have a bonded and machined flat bottom as part of their design. This works well with the Wallas ceramic cooktops, as does a fairly lightweight design (not cast iron!)...

Please be careful posting about fuels for Wallas products. Wallas builds devices that burn diesel and other devices that burn kerosene. Some can cross the line between fuels and some can't. There are no models specified in this posting/string, so no way to know which devices are being...

All the best on the future for NMI.

The reason for adding up to 3% alcohol to a diesel or kerosene tank is simply to convert any water present into something burnable. It is not a viable fuel for a Wallas device by itself. Depending on which Wallas you may have, a better choice than adding alcohol may be simply disposing of...

We can't see any way for air to get under the stove from these pictures. We will assume it is pulled from inside the hull liner below or alongside the hull. If you don't move the stove, please verify there is at least 16 square inches of air flow into the area below the stove. That thing...

This must be a fairly new boat, since it has the new 800t/220 kerosene stove. Raising your Wallas 800t/220 should not be a problem, but you may need to get some additional fuel line, return line and exhaust, although the exhaust run looks like it will still work. Make sure the stove has a way...

PLEASE do not put diesel in your Wallas 1300! It burns 1-K kerosene very well, diesel, not at all well. Another point: diesel #1 and kerosene are NOT the same thing. Thanks. Doug at Scan Marine

Georgs: You have a Wallas 95DU25E, AKA 125DU. This is a pre 2006 model. A couple tests: Try starting the stove with the lid up. Wait until you see the flashing red you described (note whether the pump is clicking), then feel the left side of the ceramic top and determine if it has become...

Georgs, Jody: Thank you for your input on this. I have been away from the forum for a while. Please note: The 125DU (aka 95DU25) has no lockout feature. The 85DU270 does. The 85 series superseded the 95 series in 2006. Either the stove is an 85DU270 or the problem was something else...

Attached you will find the manual we publish for this product in the USA. Doug at Scan 888-606-6665

An important comment about fuels: As noted before in this thread, Wallas kerosene products should burn 1K kerosene. Diesel fired Wallas products should burn diesel. Burning products like mineral spirits or other substances in Wallas kerosene devices (or diesel devices for that matter) that...

Martin: Sorry for the late reply! You can mix fuels (kerosene, Klean Heet, diesel #1 or #2) in your tank to change from kerosene or Klean Heat to diesel without emptying the tank, IF it is a diesel Wallas product (95D, 85D, 86D, 87D, 3000D, 3000Dx, 30D, 40D, 22Dt, 30Dt or 40Dt). This assumes...

C-Dory did install some model 800/220 stoves. These were intended only for use with kerosene. Diesel will take them out in short order! Just remember; If your stove has a "D" in it's name, it burns diesel. If it doesn't, it burns kerosene. Thanks for using Wallas!

Please be careful about posting fuel comments! This string of posts says nothing about what kind of Wallas device you are discussing. Wallas builds two kinds of devices - those that burn diesel and those that burn kerosene. Burning kerosene in a diesel product will usually do no harm to the...
