Stovax Stockton 5 rear air vents.

John_the_Boy

As Stovax said. The air stop on my Stockton smoke control kit only allows the vent to be closed down half way. As I look at the stove fully open is all the way to the left and closed (as far as the smoke control kit allows) is half way to the right.

Hello alleycat. Unfortunately I am not confident enough to remove all the parts to get the slider out. I found it interesting that you say it's fiddley and hard to get it positioned correctlly. My fitter didn't demonstrate time, care or thought in the art of positioning the slider. It took him less than 2 mins to do it. I am contiplating contacting another fitter to come out and take a look at it . I know this will cost me but better an extra fitting cost now than the replacement cost of a damaged stove. Out of interest how does your slider work, are you able to move it from the middle to the far left? I don't know how to post a picture sorry.

Facing the stove.
The slider moves all the way to the left (which is open with maximum "top" air).

It will then slide probably about 75% across to the right and no further.
With the original slider fitted it goes all the way to the right (fully closed).

If you look at the difference in the sliders you see an additional piece is welded to the end of the smoke control slider on one end only.

I've removed the slider from my stove to show you what the smoke control slider looks like from above.

The notch (additional piece) is very easy to distinguish and this prevents the top slider closing all the way (to the right).

The "swan neck" should be upwards (which is not clear in this image, but more obvious in the other two below).

The next image shows it's maximum operation.

and minimum operation (i.e it won't fully close).

I should note that there are no "arrows" on my slider to indicate which way to put it in.
The install instructions tell you which way to put it in and that if it isn't sat correctly it won't operate properly.

I think i had two or three goes before it "sat" correctly and slid properly as it has a tendency to try "tilt upwards" which causes it to foul and not slide.

The only way i can see it behaving as you describe is that it is incorrectly seated, upside down or manufactured incorrectly.

Thank you posting the pictures for me to see. My slider is completely different to yours. The position of the air wash control on the stove is also very different. Stovax must have redesigned the stove. I wish I could upload pictures for you to see. The only thing I can suggest is if you visit the stovax web site and search the smoke control kit instructions. The diagrams show the new slider and where it is on the new designed stove.

Somewhat confused.

I know there is a "mark 2" version of the stockton 5 but it isn't, to my knowledge, massively different in regards to the smoke control kit or airwash.

Looking at the Stovax site it looks exactly the same "cosmetically" as mine with regards to the air wash system.

I don't have the additional "secondary" air underneath the ash lip but that is, as far as i know, the difference.

Edit:-

I sort of understand what you mean now.
The slider is a different shape but the principal remains the same.
There is still a notch on the "right" end as you look at it.

Page 7 figure 10.

The airwash chamber design is still the same.

So if it won't go to the left it is either incorrectly seated or manufactured incorrectly.

Hello alleycat. Thank you for looking up the instructions and your views on this. Looking again at diagram 10 I have an incling that the fault maybe with the air wash chamber not the slider. The diagram shows a bolt fitted in it on the right. i think mine may have this fitted on the left. From looking up at the chamber bottom there is a small screw end and nut showing on the far left no matching one on the far right. The only thing I can think this is for is the bolt inside the chamber. I will have to have this part removed to check. Not sure if I can do it myself may have to be brave and tackle the fitter again or get another fitter out to check this for me. Will let you know how I get on. Thank you again for all your help.

Fingers crossed this will identify the fault.

I did notice what appears to be a "stop" on the inside of the airwash chamber on diagram 10 (as opposed to 9).

I wasn't sure if this was a mistake in the image or not as my "smoke control kit" didn't come with a modified airwash chamber housing.

On that basis i didn't mention it but i 100% agree there does appear to be something like that in the image.

I wasn't sure it would be possible to fit that in reverse but it seems like a possibility for the problem if that can be done.

Hopefully you get it sorted as it does sound like it should be a simple fix.

Hello alleycat. I had the air wash chamber and slider removed. They are completely different to the ones in diagram 10. The chamber has two rows of air holes in the bottom. Front row has 3 sets of 2 holes and rear row has 4 sets of two holes. There is no bar stopper at either end. The very small screw on the left hand serves no purpose that I can find. The slider has an extra piece added to the right end but there is also an extra piece added to the left which stops it moving all the way to the left. When you put the slider in 1 of each set of holes is blocked off in the front row and the rear. You cannot move it so that all the holes are open? When you move it to the right you only have half of a hole in all sets open. This still makes no sense to me. I have sent an e-mail to stovax asking if this is correct and to send me pictures of the smoke control chamber and slider so I can compare these to mine. It seems strange why they have designed the slider to stop all of the holes being open.

The airwash chamber, as described sounds the same as mine (minus the extra screw).

As per the images i uploaded the "modified" slider does not have an extra piece on both ends, just the one (for mine anyway).

That makes sense in the terms of preventing it sliding one direction and not both.

If you can't get any sense out of stovax my view, if the stove is "signed off", would be to replace the "modified" slider with the original and to be sensible about not closing the airwash down fully.

It makes more sense to have full proper control than a broken / backwards implementation.

I assume the original slider does work properly?
