Yet an other gas bottle stove

[dboy]

Hi everyone. Well after a few days of messing about in the garage I finally got my log burner fired up. Every thing was going well till I opened the door and I got a load of smoke out it. Now I am sure this should not happen so why is it..

I have used a 4" flu pipe and have fitted a baffle, could the flu be to narrow, is my baffel maybe to big/ in wrong place??

Can some one help me I now feel and smell like a Arbroath smokie...

Do you just get a puff of smoke when you open the door or does it smoke all the time with the door open ? if it's only just when the door is opened open the door slower.

If not it could be due to several things

Your flue may not be high enough, (most open flued gas appliances have a minimum flue length and 90 degree bends are not allowed) obstruction around flue termination point eg walls, bushes, trees ect any leaks in the flue pipe allowing air to enter or as you say the flue pipe may just be to small.

Ideally you want the flue to terminate in clear space with nothing higher than it too close to the terminal, flue pull relies on a clear air flow past the terminal to create a pull (suction), obviously any heat from below also helps.

You also need ventilation into the room to replace any air that is going up the flue + air for combustion. (I doubt this will be a problem in a garage.)

Open flues can be a right pain and fixing them can be a bit of trial and error, the weather also has a large bearing on a poor flue.

With the heater on full, the room closed up but the heater door open apply a lazy flame (candle) or smoke match across the top of the heater door opening the smoke/flame should be drawn into the heater and not blown outwards into the room.

It's a good bit of smoke not just a wee puff.. Could be the 90 degrees bend I have in the pipe but don't think I can help that.. Can the baffle be to big or in the wrong place..

Once the fire is going well it shouldn't make much smoke really, are you burning seasoned wood ? 4" is not really big enough for a flue but for a small fire in a shed it should be enough. If your baffle is removable try taking it out and have you any air going into the fire by way of vents ?

Will try and take a few pics at the weekend when I am back out in to the garage..
