done one of these at college me thinks and we were instructed to take the analysis from the primary flue through the back of the draft diverter? hope this helps. sure someone qualified will either confirm this or correct me

Depends on the model bluesky! Most have no access to the down draught diverter, hidden behind the unit.

thanks diamondgas, it is hi-spec J50, if there is no access can we make it N/A?

You should be able to pop a smoke bomb in the burner chamber I think? I usually pop them in there so you're testing the whole path through the main heatex... Best to warm the flue up first though as the main chamber is usually pretty sluggish if not heated! At least at the burner chamber you're testing the whole of the flue, primary and secondary! If there's a problem you'll sharp find out!!!

You can always remove the burner and put the smoke pellet in the heatex if you can't access the chamber!
