Wallas stove exhaust overhaul
- Thread starter timflan
- Start date
Tim,
Great job on the overhaul. The pix show your exhaust is about where mine is. I wish it were a little higher. I sometimes use the Wallas while the boat is on the trailer and the exhaust hits the carpeted guide-on bunk! I carry a piece of aluminum which I bent to shape a deflector to keep from melting the carpet.

I have a 2006 wallas single burner 800 with 220 fan . I've run the stove and heater the last couple of days in fl. but I get a residual diesel smell is this normal ? Yes the side vent is working smoke comes out . The fuel is at least 7months -?? who knows Should I change the fuel what type paraffin or diesel num 2??I'm new to this stove type When I bought the boat in April the stove worked but did not smell . I somtimes wonder what I need a Wallas stove in fl for anyway ? I wonder what a single burner is worth ? anyway just some thoughts
Hope to see some of you in fl this winter or at the seattle boat show in Jan. Jim (Duckless) on Jennykatz cc-23

I'm not going to answer, because everybody's Wallas experience seems to vary.
What I will tell you is this:
On my stove, I burn kerosene. I haven't had any trouble with it, so I keep using it. I'm not interested in advice that I should burn diesel instead, because it ain't broke now.
On my stove, I need to follow the directions in the manual and turn the burner control all the way up while the stove starts. If it's turned down, I get vaporized but unburned (and very stinky!) fuel coming out the exhaust. Once combustion has started (the red LED is steady on), I can adjust the fuel flow with the knob. During shut-down, it doesn't matter where the burner control knob I set, because the computer's controlling the process anyway.
You should contact the folks at Scan Marine.

Well, you know there is a little pan that is open to the air that holds some fuel up in the burner area -kind of like the old carbureted auto engines. Also, it is common to get some fuel on the outside of the bottle when fueling. If you smell fuel, there was probably some open to the air somewhere.
As above, I mainly use the bottled Klean kerosene designed for indoor heaters and it has a very weak odor.
If you are running or set up into the wind with only the cabin door open, it will suck air into the cabin from the Wallas exhaust. Perhaps that is the thing?

Thanks I bought the Kleen fuel drained the old and put in new fuel .Then we closed up the starboard window and door now there is very little smell thanks . At least now I can have coffee in the morning .
Another question I did turn the rotary knob all the way pressed the on /off button to on. The on button then flashed for a min or 2 then steady light on the switch Then within a 4-5 min period the combustion red light came on So far so good The wallas 800 single burner gives off lots of heat the problem is after about 15-20 min the red combustion light goes off and the heater starts cooling off but I did't touch the rotary knob what give's .I guess I need to look at troubleshooting the wallas . Does anyone have this problem?? I also have no vent if you look at my photo album (duck) page 3 all the cd-25 that have wallas's have small vents to let air in for combustion also the red light did not flash like it was overheating ?Does anyone think that it is shutting off because it needs that vent . Any cd-22 owners that have wallas's do you guys have vents ? thanks in advance

I don't have it in front of me, but I believe the "manual" (such as it is) says that the lid should be down when you are heating, rather than cooking, so that the fan comes on. Otherwise, I think you may overheat the burner and cause the stove to shut itself off. It seems to me that overheating could be more of an issue if the burner is on high (e.g., you just boiled water), but I try to be careful about it, and never leave the top open when there is nothing on the burner.
If you're having this problem with the lid down and the fan on, I have no words of advice. So far (knock on wood) we have had nothing but perfect performance from our Wallas single burner. Just returned from a delightful jaunt down Dana Passage in the wind and snow. It was nice having the heater on.
OK so I should keep the lid down and also check to see if there is an air bubble in the fuel line I guess there could be since i just refueled it .
Bill (nora lim ) Does your wallas have any venting under or near the heater because you and I have the same heater Does your red light ( combustion ) go off while you are running the heater I had the heater on today with rotary knob set at 4-5 and she ran great for about 15-20 min then the red light went off and it started to cool off?? This could be the air bubble that c-sick was talking about any other wallas owners out there with this problem.
I probably didn't mention but the wallas has not been run for over a yr or so and who knows what the original owner did so putting in new fuel was good it no longer stinks of diesel .Kleen fuel seems to be good for it no blue smoke etc. so if we get the air bubbles out this might get better I don't need to pray to the wallas gods , Thanks for all your help I love this site

jennykatz asked:
Yes, there are horizontal slots in the cabinet wall just in front of the Wallas.Does your wallas have any venting under or near the heater
I don't think so. As far as I have noticed, if the heater is on, the light is on, but then I've never really had a reason to watch it closely because the stove has always worked.Does your red light ( combustion ) go off while you are running the heater
Hi bill where are your vents located I tried to look at your album could not see any .Is it above the tundra fridge or above the cabinet doors or is it behind the helm seat??Could it be outside vents ? Bill look into my photo's (duck) photos number 60 it shows my wallas were on that picture would your vent be Thanks Jim
Jim,
I don't think I have any pictures that show the vents. They are in the cabinet wall, just above the aft cabinet door that is below the Wallas. They line up with the guts of the Wallas that hang down under the counter top. (I don't have a refrigerator.)
Based on your picture, the vent would be right above your refrigerator, just to the left of the Wallas switch.

On my '93 if I see any smoke after start-up it indicates incomplete combustion. With my stove this is due to poor fuel quality and/or a wick that needs cleaning/replacing.the side vent is working smoke comes out
That red light illuminates when the temperature at the combustion chamber is above a certain threshold. If it goes out it means that you're not maintaining that threshold. Again, poor fuel quality and/or a wick that needs cleaning/replacing.I had the heater on today with rotary knob set at 4-5 and she ran great for about 15-20 min then the red light went off and it started to cool off??
On my stove any setting below 5 risks losing the fire. I usually leave it on full and regulate the temperature by opening windows/doors.
I strongly suggest a carbon monoxide detector for anyone using a combustion type heater.
Thanks again guys Bill I will cut some holes in and put in vents that should help combustion and I will keep it at 5 or above to keep it running .where do I clean the wick where is the wick how do you get the stove out in the first place?Bill are you going to the Seattle boat show party if so could you tell me where to get info on wallas
Jim,
It's doubtful I will make it to the SBS. But as Timflan said:

I think the Wallas works best, as has been said above, at full speed. you must have it running at full speed when you shut down in order to ensure a good startup later, I think. Running below half heat risks losing prime, especially if you are low on fuel in the bottle.
I usually run at full heat, but sometimes go down to 3/4 speed if I am up and watching it. Otherwise, a cracked window or two will regulate the heat.
Also, in order to better suck up the cold air from the floor, I keep the forward (sink) cabinet door open if I am in the fore bunk. I think the vent C-Dory installs is the normal Wallas vent cut in half. (that little vent strip just under the Wallas on the cabinet face). Keeping the undersink door open reduces drafts and keeps more warm air lower in the cabin.

Scanmarine said I need more ventilation so I added( 4) 2 in round vents for soffits for a roof venting seems to work good . So what I have learned put it on full(6-7) have some ventilation put in new fuel (Kleen) and pray to the Wallas gods and then it should be good. Pat Anderson is right wallas is a overrated stove I just hope i'm finished with this nonsence and can get out and use my boat with a working stove .
