Scan Andersen 4-5 ignition vent

[Tony Mac]

Hello.

 

Getting to grips with an old Scan Andersen wood burner. I've successfully replaced the door rope seal, but researching this has lead me to more questions!

 

One thing I'm not sure of is how the ignition air vent works. I don't know how to let more air in/restrict air flow. The manual I found says to 'open' the ignition vent until the wood is burning well. But which position is open and which is closed?! The manual doesn't say and the diagram (pic attached just gives a double sided arrow! I've tried turning it different ways once I've started a fire but haven't noticed much difference to be honest! 

 

I'm sure I'm being very thick but would appreciate your opinion!

 

Pics of the air vent knob and manual attached! With air vent pics I've taken, one pic shows the knob turned so that the opening is at the top and the other pic shows the opening at the bottom.

 

Thanks in advance!

Bottom picture is open, air gets in through the gap. If you don't noticed much difference open or closed suggests more air is getting in at a low level. Is the ash pan sealing when it is closed as air entering under the grate will make wood burn more fiercely.

Thanks for your reply openspaceman! Thanks to your advice I have found that the ash pan is not sealing properly. The handle to open and close it is stiff and I'm not able to open and close it effectively. This is another issue I now need to solve!
