Isokern Chimney Help

[WiltshireLink]

Hi, 

 

Just starting to install my chimney, Isokern pumice liner.

 

I have spoke to Isokern but no joy...

 

Basically we have the 45° T section going into the house and upwards. But what do I do with the bit below on the T ? Does it need a plug? Surely it's not left open? 

 

I know I need a soot door to sweep/access which I've accounted for but I can't think this hole at the bottom stays open?! Ta

Perhaps give these guys a call.

there's a base fitting with a drain hole in our Swift Air setup, I think Isokern should be the same? "Base stone with drain" is the item.

I need the pumice liner though, not the ceramic

 

I need a tee cap but can find kne anywhere! Maybe I can adapt an aluminium one?
